UM980 Board Behind Most Premium Receivers
Quick Answer — Which Chinese GNSS Brand Should You Choose?

Hi-Target leads on brand recognition and installed base. South Surveying uses self-developed ComNav boards. APEKS delivers the same Unicore UM980 hardware as tier-1 brands at roughly half the international price, with a single-exclusive-distributor model that protects partner margins.

Walk into any surveying equipment exhibition in Jakarta, Riyadh, Lagos, or São Paulo and you will find at least a dozen Chinese GNSS brands competing for the same buyer. The marketing materials look nearly identical: 1408 channels, 120° IMU, IP67/IK08, 2W UHF radio, built-in 4G. The prices range from $3,500 to $12,000 for what appears to be the same product. One brand claims "self-developed technology". Another emphasises a 20-year history. A third is aggressively undercutting everyone on price.

The buyer who understands the supply chain reality — who makes the boards, who controls the firmware, how each brand structures its distribution — makes a fundamentally better purchasing decision than one who compares spec sheets alone. This guide provides that supply chain reality, evaluates 8 major Chinese GNSS manufacturers honestly (including their weaknesses), and gives you the decision framework to match the right brand to your specific situation.

China's RTK GNSS Export Industry in 2026

China has become the dominant supplier of professional RTK GNSS receivers in Belt and Road markets. Chinese-manufactured receivers now account for the majority of new equipment purchases in Indonesia, the Middle East, sub-Saharan Africa, Southeast Asia, and Latin America — largely because they deliver hardware specifications that were once exclusive to $20,000+ Trimble or Leica systems, at one-quarter to one-third of the price.

The Chinese GNSS manufacturing base is concentrated in three cities: Shanghai (APEKS, ComNav), Guangzhou (Hi-Target, South Surveying, Stonex), and Xi'an / Beijing (Unistrong, Unicore). Note that Unicore Communications is the primary board supplier, not a complete GNSS brand.

Understanding this concentration is the starting point for any serious evaluation of Chinese GNSS brands.

The Truth About Chinese GNSS Boards

This is the section most manufacturers would prefer you skip. The supply chain reality of Chinese RTK GNSS is straightforward once you know where to look.

Early on (pre-2015), Chinese RTK brands universally used Trimble OEM boards, later shifting to Hemisphere (US). By around 2020, the industry almost entirely transitioned to domestic Unicore UM980 boards. Currently, the market is dominated by:

The Three GNSS Board Suppliers Behind Chinese RTK Receivers

1
Unicore Communications (和芯星通) — UM980 Board
The dominant mainstream supplier. Unicore's UM980 module (1408 tracking channels, 7 constellations: GPS, BDS, GLONASS, Galileo, QZSS, NavIC, SBAS) powers the core GNSS processing in receivers from Hi-Target, APEKS, Stonex, FOIF, Unistrong, E-Survey, and the majority of mid-to-premium Chinese brands. The UM980 is a mature, production-proven board with well-documented performance characteristics. When two receivers both use the UM980, their raw GNSS positioning performance ceiling is identical. Differentiation happens in firmware quality, IMU integration, antenna design, and field software.
2
ComNav Technology (司南) — K8 Board
The only major Chinese GNSS company that manufactures its own GNSS processing boards. ComNav's K8 board claims 1598 tracking channels. South Surveying (and its sub-brand Sanding) uses ComNav boards in its receiver line. Self-developed boards give genuine independence from Unicore and theoretical differentiation in algorithm implementation. In practice, field reports from dense-canopy and high-multipath environments indicate that ComNav board stability has historically trailed UM980 maturity, though this gap has narrowed in recent firmware generations.
3
Hemisphere GNSS (US-origin) — Legacy
A US-origin GNSS board supplier that was once common in Chinese receivers. Hemisphere boards have largely been phased out of new Chinese GNSS products since the mid-2020s, driven by US export control considerations and the maturation of domestic alternatives. You may encounter Hemisphere-based receivers in older equipment or secondary market purchases. For new equipment evaluation, Hemisphere-based receivers are not the current generation.

What this means for buyers: If a receiver uses the Unicore UM980 board, its raw positioning accuracy is identical to every other UM980-based receiver. The real comparison is firmware, IMU implementation, antenna quality, field software, build quality, and after-sales support. "Self-developed technology" claims from UM980-based brands refer to their firmware and software layers — not the core positioning engine.

Ask any supplier directly: "Which GNSS processing board does this receiver use?" Reluctance to answer is itself informative.

The Pricing Reality: Why International Version Costs 2× More

Consider a receiver built around the Unicore UM980 board, with a 120° IMU, IP67 rating, 2W UHF radio, built-in 4G modem, and 6-hour battery. This hardware configuration — broadly similar across Hi-Target and APEKS — carries dramatically different price tags depending on the brand:

Brand Model Board Export Price (Approx) Distribution Model
Hi-Target V500 Unicore UM980 $7,500–9,500 Multiple dealers per country
South Surveying Galaxy G7 ComNav board $6,500–8,500 Multiple dealers per country
APEKS GNSS AP40 Laser+ Unicore UM980 $3,500–4,500 Single exclusive dealer per country

The 50–60% price gap between tier-1 brands and APEKS is not a quality gap. It is a distribution model gap.

Tier-1 Chinese brands maintain expensive multi-distributor networks: typically three or more dealers per country competing on the same product line. Internal price competition drives distributor margins down, forces dealers to inflate retail pricing to maintain profitability, and creates fragmented after-sales responsibility — when a problem occurs, three dealers point at each other.

APEKS operates a single-exclusive-distributor model: one partner per country receives 100% of that market's leads, holds exclusive pricing rights, and earns substantially higher per-unit margin. This passes through directly to end-buyer pricing — the same UM980 hardware platform, at half the cost — while giving the distributor a defensible market position rather than a race to the bottom against two domestic competitors.

For distributors evaluating which brand to carry: the financial arithmetic is straightforward. Higher margin per unit, zero internal competition, and exclusive territory protection add up to a more sustainable business than representing a tier-1 brand where three local competitors are undercutting you on the same product.

1. Hi-Target (中海达)

Founded: 2003 | HQ: Guangzhou | Board: Unicore UM980 | Listed: Shenzhen Stock Exchange

Market position: Hi-Target is a leading Chinese GNSS exporter. The V200 series, once the company's flagship rover, has been discontinued; current export focus is on the V500 and V600L models.

Strengths: Strong R&D investment as a listed company, Hi-Survey software with good localisation support for Asian and Middle Eastern datums, competitive total station and controller product line alongside GNSS. Hi-Target has invested heavily in tilt IMU development and their IMU implementation is considered mature.

Limitations: International version pricing follows the same premium model as other legacy brands. Multiple-dealer market structure creates the same margin compression issues. Brand awareness in sub-Saharan Africa and South America is still developing.

Best for: Markets where Hi-Target has established service infrastructure (Southeast Asia, Middle East). Buyers who require total station and GNSS from the same brand ecosystem.

Key models: V500, V600L

Export price range: $7,500–10,000 (full kit)

2. South Surveying & Mapping (南方测绘)

Founded: 1989 | HQ: Guangzhou | Board: ComNav self-developed | Listed: No

Market position: South is the oldest Chinese surveying instrument company still operating under its original name and the only major RTK brand that uses ComNav's self-developed boards rather than Unicore. This gives South genuine hardware differentiation — for better or worse.

Strengths: 35+ years of manufacturing history, the broadest product catalogue in Chinese surveying (total stations, levels, theodolites, GNSS, GIS handhelds), strong domestic government and education sector relationships. South's Galaxy G7 is well-regarded in markets where South has established distributor relationships.

Limitations: ComNav board signal tracking stability in challenging environments (heavy canopy, dense urban) has historically trailed UM980-based receivers — though recent ComNav firmware updates have reduced this gap. South's international brand development has lagged behind Hi-Target; distributor networks are thinner outside Asia. Less investment in modern IMU tilt technology compared to Unicore-platform competitors.

Best for: Buyers who prefer genuine hardware diversity (non-UM980), established South distributor relationship markets (parts of Southeast Asia, some African markets), or buyers requiring the broadest possible product catalogue from one supplier.

Key models: Galaxy G7, S82-V, N3 Pro, ALPS1

Export price range: $6,500–9,000 (full kit)

South's sub-brand Sanding Technology uses the same ComNav boards and targets highly price-sensitive markets.

3. APEKS GNSS (阿配科斯)

Founded: 2018 | HQ: Shanghai | Board: Unicore UM980 | Listed: No

Market position: APEKS occupies a specific and deliberate position in the Chinese GNSS export market: the same Unicore UM980 hardware platform used by Hi-Target, delivered at approximately half the international version price, through a single-exclusive-distributor model that protects partner margins and eliminates internal competition.

🏆 Independent Competition Result — GNSS Battle 2026: APEKS entered seven receivers into GNSS Battle 2026, an independent 21-receiver competition held in Russia testing accuracy and signal performance in urban multipath and forest canopy conditions. Final results: AP80 Pro 🥇 Grand Champion (1st), AP20 AR 🥈 2nd, AP40 Laser+ 4th, MAX5 5th. Four APEKS models placed in the top 5. Competing brands included Geobox, PrinCe (by CHC Navigation / CHCNAV), Stonex, EFT, and others. No other manufacturer placed more than one receiver in the top 5.

Strengths: International firmware with no geo-fence restrictions or domestic-only firmware locks — global OTA updates work identically whether the receiver is in Jakarta, Riyadh, Lagos, or São Paulo. For markets with limited CORS coverage — including Saudi Arabia, Nigeria, and remote infrastructure sites — APEKS's Base+Rover 1+1 deployment (AP10 or AP20 as base + any rover model) provides centimetre-accurate RTK with no internet dependency and no recurring CORS subscription fees. Complete product line spanning GNSS receivers (AP10 through AP80 Pro), MAX5 dedicated base station with 5W LoRa and 25 km range, APS1 handheld RTK, AM02 total station series, APL32 auto level, APD02 theodolite, CS/TS controller lineup, and an upcoming Handheld SLAM scanner. 120° calibration-free IMU and IP67/IK08 across the full GNSS range. Exclusive territory distribution eliminates local price competition for partners and delivers end-user pricing roughly 50% below comparable Hi-Target international kits.

Limitations: Smaller installed base than Hi-Target, meaning fewer documented third-party software integrations and less available independent long-term reliability data. Brand recognition in Western Europe and North America is still developing. Service network relies primarily on exclusive distributors rather than company-owned offices; service quality is therefore distributor-dependent by market.

Best for: Distributors seeking exclusive territory rights with protected margins in unrepresented or under-served markets. End-buyers in Belt and Road markets — Indonesia, Saudi Arabia, UAE, Egypt, Turkey, Brazil, Nigeria — who need international-firmware GNSS with full product line availability at competitive pricing. Survey companies that want to consolidate equipment procurement (GNSS + total station + controller + base) under a single vendor.

Key models: AP80 Pro (Laser+AR+Vision+3D Modeling ALL IN ONE), AP60 Vision, AP40 Laser+ (120m green laser, dual camera), MAX5 (5W LoRa base station, 25km range), AP10/AP20

Export price range: $3,500–4,500 for AP40 Laser+ full kit; AP80 Pro on request

4. Stonex

Founded: 2004 | HQ: Milan, Italy (manufacturing: Guangzhou, China) | Board: Unicore platform | Listed: No

Market position: Stonex is technically an Italian company with Chinese manufacturing operations — a hybrid that gives it European brand positioning with Chinese production cost advantages. This makes Stonex uniquely competitive in European and Latin American markets where "Made in China" carries procurement resistance but "Italian design" does not.

Strengths: European brand identity opens government and institutional tender doors that pure Chinese brands sometimes cannot access. Stonex has established distributor networks across Europe, Latin America, and the Middle East. Build quality and firmware QA benefit from Italian engineering oversight. Strong total station and scanner product line alongside GNSS.

Limitations: Price premium over comparable pure-Chinese brands for functionally equivalent hardware. Smaller model range than APEKS. Distribution is thinner in Africa and South/Southeast Asia compared to Chinese-branded competitors.

Best for: European buyers with procurement policies favouring EU-origin products. Latin American institutional buyers. Markets where Italian brand association adds credibility in the sales process.

Key models: S900A, S9ii, S980A

Export price range: $7,000–10,500 (full kit)

5. ComNav Technology (司南导航)

Founded: 2003 | HQ: Shanghai | Board: Self-developed (K8 series, 1598 channels) | Listed: Yes — Shanghai Stock Exchange

Market position: ComNav occupies a dual role in the Chinese GNSS industry: it is simultaneously a GNSS board OEM supplier to other manufacturers (including South Surveying) and a complete receiver brand in its own right. This dual position gives ComNav unique insight into the supply chain — and a genuine claim to self-developed technology that most Chinese brands cannot honestly make.

Strengths: The only major Chinese brand manufacturing its own GNSS processing boards, giving genuine hardware independence. 1598-channel specification on K8 boards exceeds Unicore UM980's 1408 channels on paper. Competitive pricing on OEM board supply for integrators. Strong adoption in machine control and UAV applications where board-level integration matters.

Limitations: Self-developed board maturity in challenging signal environments (dense canopy, high multipath urban) has historically trailed UM980 performance — though recent firmware generations have narrowed this gap significantly. ComNav's retail receiver brand is less recognised than Hi-Target or South in most export markets. After-sales support infrastructure outside China is limited to distributor networks without company-owned service centres.

Best for: OEM integrators who need a GNSS board supplier for custom products. Buyers specifically requiring non-Unicore hardware diversity. Machine control and UAV integration applications where ComNav's board-level access is an advantage.

Key models: N3, LU8, K823 (OEM board)

Export price range: $4,500–7,000 (complete receiver); OEM boards priced separately

6. FOIF (苏一光)

Founded: 1958 | HQ: Suzhou | Board: Unicore UM980 | Listed: No (state-owned enterprise background)

Market position: FOIF is one of China's oldest optical and surveying instrument manufacturers, tracing its origins to a state-owned factory established in 1958. The brand carries significant heritage weight in markets where it has been selling total stations and theodolites for decades — particularly in parts of Africa and the Middle East where FOIF equipment entered through government-to-government development projects.

Strengths: Exceptional brand recognition in legacy markets where FOIF has been present for 30+ years. Complete traditional optics product line (theodolites, automatic levels, total stations) that GNSS-only brands cannot match. Price-competitive across the full product range.

Limitations: GNSS receiver technology development has lagged behind agile private competitors — FOIF's RTK range is less technically current than Hi-Target or APEKS. Software ecosystem for GNSS field work is less mature. Limited investment in modern IMU tilt compensation and advanced field software compared to rivals.

Best for: Markets where FOIF has existing relationships and where buyers are upgrading from FOIF total stations to GNSS. Buyers who need traditional optics alongside entry-level GNSS from one supplier.

Key models: A90, A80, A66 MAX, RTS series (total stations)

Export price range: $4,500–7,000 (GNSS full kit)

7. Unistrong (合众思壮)

Founded: 1994 | HQ: Beijing | Board: Mixed (Unicore primary) | Listed: Shenzhen Stock Exchange

Market position: Unistrong is one of China's oldest GPS/GNSS companies and is majority-owned by state-connected investment entities. Its primary strength is the domestic Chinese government market — land administration, national mapping projects, and military-adjacent surveying contracts. International export is a secondary focus.

Strengths: Deep relationships with Chinese government agencies give Unistrong access to large domestic contracts that purely commercial brands cannot easily compete for. Listed company with published financials. Broad product range including GIS data collectors and LiDAR scanning systems alongside RTK GNSS.

Limitations: International export network is significantly thinner than Hi-Target or South. Product development cycles are slower than agile private competitors. Firmware internationalisation and non-Chinese language support has historically been secondary priority. Domestic-market orientation means international buyers get less attention from product and support teams.

Best for: Buyers with specific requirements for Chinese government procurement documentation or domestic Chinese project compliance. Not typically the first choice for international export-market buyers.

Key models: G970 Pro, MG868S

Export price range: $6,000–8,500 (full kit)

Unistrong's overseas brand, E-Survey, focuses exclusively on international markets and is not sold domestically in China.

8. E-Survey

Founded: 2007 | HQ: International brand of Unistrong | Board: Unicore UM980 | Listed: Via parent Unistrong (Shenzhen)

Market position: E-Survey is the dedicated international export brand of Unistrong (合众思壮). Unlike Unistrong's domestic-focused product line, E-Survey is built exclusively for export markets — the brand does not sell in China. This gives E-Survey a fundamentally different positioning from its parent company: international firmware, export-oriented product development, and distributor networks built for overseas markets.

Strengths: Backed by Unistrong's manufacturing and R&D resources while maintaining a separate international identity. Competitive pricing on UM980-based hardware. Growing presence in Africa, Middle East, and Southeast Asia. Products share the same core hardware platform as Unistrong but with international firmware and support.

Limitations: Less brand recognition than Hi-Target or South in most export markets. Distribution networks are still developing in many regions. Being tied to a parent company focused on domestic China means product roadmap priorities may not always align with international market needs.

Best for: Buyers in Africa, Middle East, and Southeast Asia seeking a competitively priced UM980-based receiver with international firmware support. Distributors in markets where E-Survey has established local presence.

Key models: E600 Pro, E500

Export price range: $4,000–7,000 (full kit)

How to Choose — Decision Tree by Use Case

Match Your Situation to the Right Brand

1
You need zero geo-fence risk and global OTA firmware support
APEKS (explicit international-version policy, global OTA confirmed), Stonex (Italian entity, low geo-fence risk). Avoid Unistrong and verify explicitly with Hi-Target that international firmware includes global OTA before purchasing.
2
You are a distributor seeking exclusive territory rights
APEKS is the only brand in this list with a stated single-exclusive-distributor model. One partner per country, full lead protection, and no internal price competition from other local dealers. Apply at /become-our-dealer/
3
Budget is the primary constraint (under $5,000 for full kit)
APEKS (UM980, complete product line, $3,500–4,500).
4
Tender specification requires named brand with longest track record
Hi-Target. Their installed base and reference project lists are among the longest of any Chinese brand. Accept the price premium as a tender compliance cost. Note: In GNSS Battle 2026 (independent 21-receiver competition, Russia), APEKS AP80 Pro took Grand Champion and four APEKS models placed in the top 5. PrinCe i35XR (CHC Navigation / CHCNAV) also competed. For buyers where tender compliance requires a named brand, Hi-Target remains the choice — but for performance-first procurement, the independent competition data favours APEKS.
5
You need a complete equipment line: GNSS + total station + level + controller from one supplier
APEKS (AP-series GNSS + AM02 total station + APL32 level + CS/TS controllers — most complete single-supplier catalogue in this price segment), Hi-Target, South.
6
You operate primarily in Belt and Road export markets (Indonesia, Saudi Arabia, Brazil, Turkey, Egypt, Nigeria)
APEKS (active distribution development in all six markets), Stonex (strong in LatAm). Hi-Target is also present but at 2× the price point.
7
You need GNSS boards or OEM integration (not a complete field receiver)
ComNav (self-developed boards, direct OEM sales), Unicore direct (UM980 board procurement).

What Manufacturers Don't Tell You

1
The Geo-Fence Firmware Problem
Several Chinese GNSS brands ship two firmware variants: a domestic version for the Chinese market with unrestricted feature access and update availability, and an international version that may have restricted firmware update pathways when operated outside China. Over time, outdated firmware causes RTCM version incompatibilities with updated CORS networks, constellation tracking regressions as new signals are activated, and loss of compatibility with third-party software that has updated its GNSS communication protocols.

The test is simple: before purchasing, ask your supplier to demonstrate an OTA firmware update performed from a network connection outside China. A genuine international-version receiver with global OTA support passes this test immediately. Reluctance to demonstrate it is the answer.
2
"Self-Developed Technology" in Context
Almost every Chinese GNSS brand's marketing materials claim "self-developed technology" or "independent R&D". In context, this almost always refers to firmware, field software, IMU integration, and hardware shell design — not the core GNSS processing board. For the vast majority of Chinese brands, the GNSS positioning engine is Unicore UM980, purchased as a module and integrated into the company's own hardware design.

This is not inherently deceptive — Unicore UM980 is a high-quality board and the differentiation in firmware and software is real. But buyers should understand that "self-developed GNSS receiver" and "self-developed GNSS board" are very different claims. Only ComNav in this list can honestly claim the latter.
3
Multi-Dealer Distribution Creates Hidden Costs
When a brand operates three competing dealers in your country, the structural incentives push all three towards volume discounting to win deals. Margins compress. Dealers cut after-sales support to compensate. Service calls go unanswered because it is unclear whose customer you are. Warranty disputes get lost between dealers who each claim the other sold the unit.

A single exclusive distributor model reverses these incentives: one partner owns every customer in the market, invests in service capability, and protects the relationship because there is no competitor to take the account. For end-buyers, this translates to better post-sales support regardless of price. For distributor partners, it means building a real business rather than fighting a race to the bottom.

5 Buying Mistakes to Avoid

  • MISTAKE 1 — Comparing spec sheets without asking about the board. Two receivers with identical specifications at very different prices almost certainly use the same GNSS board. Ask: "What GNSS processing board does this receiver use?" The honest answer is UM980 for most brands. The specification advantage is in firmware and software, not hardware.
  • MISTAKE 2 — Assuming "international version" means global OTA firmware. International version usually means the receiver works outside China. It does not automatically mean firmware updates work globally. Confirm specifically that OTA firmware updates function from a non-Chinese network connection before purchasing.
  • MISTAKE 3 — Buying based on brand recognition without checking local distribution quality. A tier-1 brand name means nothing if the local distributor has three competing dealers who don't return calls. Verify the specific distributor's service capability and customer references in your market before committing to a brand.
  • MISTAKE 4 — Paying the international version premium for the same UM980 hardware. If your project does not require a specific brand name for tender compliance, there is no hardware justification for paying $8,000–12,000 for a UM980-based receiver when equivalent UM980-based hardware is available at $3,500–4,500. The accuracy ceiling is identical.
  • MISTAKE 5 — Not verifying firmware update capability before the warranty period ends. Request a live OTA firmware update demonstration before or immediately after purchase. If the receiver cannot update firmware via OTA from your country, negotiate a solution with the supplier before the warranty period ends — not after a CORS compatibility issue surfaces two years into the project.

FAQ — Chinese RTK GNSS Manufacturers

Are Chinese GNSS receivers as accurate as Trimble or Leica?
For standard RTK field survey applications, yes. Chinese receivers using the Unicore UM980 board achieve ±8 mm horizontal and ±15 mm vertical Fixed solution accuracy — identical to the theoretical performance of Trimble R12i or Leica GS18 under the same conditions. The practical differences are in software ecosystem depth, multi-sensor integration, and long-term firmware support. For standard cadastral, topographic, and construction survey, Chinese UM980-based receivers are technically equivalent at one-quarter to one-third of the price.
What is the Unicore UM980 board and which Chinese brands use it?
The Unicore UM980 is a 1408-channel, 7-constellation GNSS processing module manufactured by Unicore Communications (和芯星通), a Beijing-based company majority-owned by Alibaba. It is the dominant GNSS board in the Chinese RTK receiver industry. Hi-Target, APEKS, Stonex, FOIF, E-Survey, and many others use UM980 as their core GNSS engine. The board is commercially available — meaning any manufacturer can integrate it. Differentiation between UM980-based brands comes from firmware, IMU integration, antenna design, and field software.
Why is APEKS so much cheaper than Hi-Target for similar specifications?
Three factors account for the price gap: first, APEKS uses the same Unicore UM980 board as Hi-Target but prices it without the multi-dealer distribution overhead that tier-1 brands carry. Second, APEKS operates a single-exclusive-distributor model that eliminates internal price competition and passes savings directly to end-buyers. Third, APEKS's smaller marketing budget and lower brand premium cost reduce overhead. The hardware specifications — board, IMU, IP rating, channels — are comparable. You are paying less for the brand name, not for lower accuracy.
What is the difference between domestic version and international version Chinese GNSS?
Domestic version receivers are firmware-configured for the Chinese market, with full feature access and unrestricted firmware update availability within China. International versions are sold for use outside China. The key difference is whether firmware updates work globally via OTA. Some brands' international versions restrict firmware updates to require connection through Chinese servers or company-managed update channels that may not function reliably outside China. A genuine international version with global OTA support updates from any internet connection, anywhere. Always confirm this specifically before purchasing.
Can Chinese GNSS receivers work with InaCORS, NGOSA, TrigNet, and other national CORS networks?
Yes. All modern Chinese RTK receivers support NTRIP v1 and v2 protocols, which are the standard connection methods for all national CORS networks including Indonesia's InaCORS, Saudi Arabia's NGOSA, South Africa's TrigNet, Brazil's RBMC, and Turkey's CORS-TR. Compatibility is protocol-based, not brand-dependent. The only caveat is firmware version: receivers with outdated firmware may have RTCM version incompatibilities with updated CORS networks. This is why global OTA firmware update capability matters for receivers used in export markets.
How do I become a distributor for a Chinese GNSS brand?
Most Chinese GNSS brands accept distributor applications through their websites. The process typically involves a company profile submission, market coverage assessment, and minimum order commitment discussion. For brands with multi-dealer models (Hi-Target, South), territory exclusivity is not guaranteed — you may be one of several dealers in your country. APEKS operates a single-exclusive-distributor model with explicit territory protection: one qualified partner per country with exclusive rights to that market's leads and pricing. Applications for unrepresented markets are reviewed at /become-our-dealer/
Which Chinese GNSS brand has the best after-sales support internationally?
Hi-Target has among the broadest company-owned service infrastructure internationally, with offices or authorised service centres across Southeast Asia and the Middle East. For brands without company-owned service centres (including APEKS), after-sales quality depends entirely on the local exclusive distributor — a strong exclusive partner delivers better support than a weak Hi-Target multi-dealer in the same market. Evaluate the specific distributor in your market, not just the brand's global reputation.
Is South Surveying's ComNav board better or worse than Unicore UM980?
ComNav's K8 board claims 1598 channels versus UM980's 1408 — a higher number on paper. In clean-sky, open-terrain conditions, both boards deliver equivalent RTK accuracy. Field experience in challenging environments (dense equatorial forest canopy, high-multipath urban canyons) has historically favoured UM980's more mature signal tracking algorithms, though recent ComNav firmware generations have significantly reduced this gap. For standard land survey applications, both are professionally capable. For consistently demanding environments, UM980's longer production history and larger installed base provide more independently documented performance data.
What is the typical lead time for ordering from a Chinese GNSS manufacturer?
Standard stock models typically ship within 3–7 business days from Chinese warehouses. International freight to most Belt and Road markets (Indonesia, Saudi Arabia, UAE, Egypt, Turkey, Brazil, Nigeria) takes 5–12 business days by express courier and 20–35 days by sea freight. Custom configurations or large-volume orders may require 2–4 weeks production time. Distributors holding local inventory can deliver same-day or next-day in their markets — one advantage of an exclusive distributor model with invested local stock.
How long do Chinese RTK GNSS receivers typically last in field conditions?
With IP67/IK08-rated equipment used within its environmental specifications, a well-maintained Chinese RTK receiver typically delivers 5–8 years of productive service. The limiting factors are usually battery capacity degradation (2–3 years before noticeable reduction in runtime), firmware obsolescence relative to updated CORS network protocols (mitigated by global OTA support), and physical connector wear. Equipment used in harsh equatorial conditions (Indonesia, sub-Saharan Africa) should have port covers used consistently to prevent connector corrosion from humidity and particulate contamination.

SAME UM980 BOARD. HALF THE PRICE. EXCLUSIVE TERRITORY.

APEKS delivers Unicore UM980 hardware with 120° calibration-free IMU, global OTA firmware, and the most complete product line in this price segment — at approximately half the international version price of Hi-Target or South Surveying. Single exclusive distributor per country. No internal competition. Full margin protection.
