What is the name of China's GPS system?

The name of China's GPS system is indeed Compass, also known as BeiDou. This system represents China's efforts to establish an independent navigation satellite system that provides positioning, navigation, and timing services globally. The BeiDou system is part of a larger trend where countries are developing their own global navigation satellite systems to enhance their independence from other nations' systems, such as the United States' GPS.

BeiDou offers various services, including short message communication and has applications in transportation, agriculture, and disaster relief, among other sectors. It has been fully operational, providing services not only to China but to users worldwide, showcasing significant advances in satellite technology and navigation precision.

In contrast, the other answers refer to systems from different countries: IRNSS is India's regional navigation satellite system, Galileo is the European Union's system, and GLONASS is Russia's global navigation satellite system. Each of these serves similar functions but is not associated with China.
