1. GNSS: Global Navigation Satellite System, is the collective name for the five major satellite navigation and positioning systems of China's Beidou System (BDS), US GPS, Russia's GLONASS, EU's Galileo, and Japan's QZSS, and can also refer to their enhanced systems. For a long time, GNSS has two translation names: global satellite navigation system and global navigation satellite system. system.
In essence, GNSS is a global position and time determination system, including many satellite constellations, receivers and monitoring systems. In other words, it is a large system composed of multiple satellite navigation and positioning systems and their enhanced systems.
2. The US GPS positioning satellite, a system for real-time positioning and navigation around the world, is called the Global Satellite Positioning System, or GPS for short. GPS is an all-round, all-weather, all-time, high-precision satellite navigation system developed and established by the US Department of Defense.
3. The wearable device has independent satellite positioning capability, which means that the device contains related positioning chips, antennas and other devices, and can still obtain satellite positioning information in the outdoor/in an environment with satellite signals even when the mobile phone is disconnected, for use in Sports items on wearable devices such as running, cycling, and mountaineering, and record information such as motion tracks.

Remarks:
The independent satellite positioning of wearable devices is currently only used for the positioning of sports events. Functions such as viewing the positioning of wearable devices on the mobile phone cannot be realized.
