The GNSS system will be completed in six years, with accuracy comparable to GPS.

China has so far successfully launched four GNSS navigation test satellites and 16 GNSS navigation satellites. The second phase of the GNSS Navigation Satellite System’s three‑step development strategy—regional constellation deployment—has been smoothly accomplished, and the system’s accuracy and performance in the Asia‑Pacific region are comparable to those of the Global Positioning System (GPS). He stated that China should accelerate the formulation and refinement of policies related to the navigation industry to guide its orderly development.

“Our country’s GNSS Satellite Navigation System has developed at a very rapid pace,” said Yang Yuanxi. From the completion of the GNSS Satellite Navigation Test System in 2000 to the official launch of regional services by the end of 2012—when the system began providing continuous, passive positioning, navigation, and timing services across most of the Asia-Pacific region—China achieved this milestone in just over a decade, becoming one of the world’s four major satellite positioning and navigation systems.

According to the plan, by around 2020, China will have completed the GNSS Global Navigation Satellite System, comprising five geostationary satellites and 30 non‑geostationary satellites, which will provide high‑precision, highly reliable positioning, navigation, and timing services worldwide.

“The GNSS Navigation Satellite System is a global satellite navigation system independently developed and operated by China, and it is compatible with and interoperable with other satellite navigation systems worldwide. Although its technological capabilities still have room for improvement at present, in terms of performance, its accuracy and service levels in the Asia-Pacific region are comparable to those of GPS,” said Yang Yuanxi. “Moreover, GNSS has its own distinctive features: in addition to navigation, positioning, and timing functions, it also provides communication services. By continuing to leverage its unique strengths and delivering high‑quality services, it will undoubtedly secure a solid foothold both domestically and in future international markets.”
