Five Chinese GNSS suppliers target UAV positioning demand

Chinese companies are gaining ground in high-precision GNSS for drones as UAV demand rises across surveying, agriculture, logistics and inspection. The market is growing fast, and suppliers are competing on RTK accuracy, anti-jamming features, customization and certification.

Why it matters: - High-precision GNSS is becoming a core enabling technology for UAVs used in surveying, agriculture, logistics and inspection. - The global high-precision GNSS market was valued at USD 7.8 billion in 2024 and is projected to reach USD 20.6 billion by 2033, according to Dataintelo. - The global high-precision GNSS module market was estimated at USD 1.5 billion in 2024 and is expected to reach USD 4.5 billion by 2035, according to Market Research Future. - Chinese manufacturers are positioned to compete on pricing, OEM flexibility and fast product iteration.

What happened: - A profile of five Chinese GNSS suppliers highlighted companies serving UAV positioning and drone navigation needs. - JUMPSTAR CO., LIMITED is headquartered in Shenzhen and was founded in 2013. - Unicore Communications is based in Beijing and develops GNSS baseband and RF chipsets. - CHC Navigation Technology Co., Ltd. is headquartered in Shanghai and supplies geospatial and GNSS systems. - Hi-Target Surveying Instrument Co., Ltd. is based in Guangzhou and has expanded from surveying equipment into UAV-focused GNSS products. - Beijing ByNav Technology Co., Ltd. focuses on BeiDou navigation and positioning solutions.

The details: - JUMPSTAR operates a 5,000-square-meter facility, employs about 200 people and reports annual output of 100,000 units. - More than 70% of JUMPSTAR products are exported to the EU, the U.S. and the Middle East. - JUMPSTAR’s UAV product lineup includes RTK modules, GPS antennas, GNSS receivers and anti-jamming antennas. - The P-Box-X10 uses multi-constellation, triple-frequency GNSS and 544 hardware channels. - The P-Box-X10 delivers RTK horizontal accuracy of 0.6 cm + 0.5 ppm and dual-antenna heading accuracy of 0.03 degrees at a 5-meter baseline. - The receiver includes AIM+ anti-jamming, OSNMA anti-spoofing and 100 Hz positioning and observation output. - The X43H-AH is a compact multi-frequency RTK receiver with 789 channels, dual-antenna heading and support for major GNSS constellations. - JUMPSTAR offers OEM and ODM customization for modules, PCBA, antennas and firmware. - JUMPSTAR says monthly capacity reaches 50,000 units and typical lead time is 30 days. - JUMPSTAR holds ISO 9001:2015 certification. - A drone manufacturer client has deployed more than 500 P-Box-X10 units over five years and cited centimeter-level RTK performance and anti-jamming capability. - Unicore’s UM980 and UM960 series are self-developed multi-frequency, multi-constellation SoCs used in UAV RTK modules. - Unicore emphasizes lower power use, smaller size and lower cost for mass-market drone platforms. - Unicore supports GPS and BeiDou signals and provides software tools for flight-controller integration. - CHCNAV sells RTK receivers, UAV LiDAR systems and GNSS base stations. - CHCNAV’s iBase and i70 series are used by drone operators for survey and mapping work. - CHCNAV has distribution in more than 100 countries and offers a software ecosystem plus after-sales support. - Hi-Target’s V100 GNSS receiver and board-level products provide RTK-level accuracy for agricultural drones and aerial mapping platforms. - Hi-Target’s position in the market rests on its surveying workflows expertise and brand trust in China. - ByNav develops high-precision GNSS boards and modules for UAV navigation, autonomous driving and precision agriculture. - ByNav focuses on multi-constellation compatibility and robust performance in difficult signal environments. - ByNav is known for dual-antenna heading algorithms and integrated GNSS+IMU navigation in compact embedded designs.

Between the lines: - The UAV GNSS market is moving from basic positioning toward tighter accuracy, stronger interference resistance and easier system integration. - JUMPSTAR’s combination of exported volume, OEM/ODM services and certified production suggests a push toward contract manufacturing for drone builders. - China’s suppliers are competing not only on hardware performance but also on software tools, support and integration speed.

What's next: - Demand for centimeter-level positioning is likely to keep rising as UAVs take on more commercial and industrial work. - Buyers will keep comparing RTK accuracy, multi-frequency support, anti-jamming features, certification status and customization capacity. - Chinese GNSS vendors are likely to expand further as drone makers look for scalable suppliers with shorter development cycles.

The bottom line: - High-precision GNSS is now a strategic part of the UAV supply chain, and Chinese suppliers are building strong positions around performance, flexibility and cost.
