GNSS, Global Navigation Satellite System. The GNSS networks in use are.
- BeiDou Navigation Satellite System
- BeiDou-2 (Formally known as Compass)
- Global’naya Navigatsionnaya Sputnikovaya Sistema
- Global Positioning System
- Quasi-Zenith Satellite System
Devices utilising one or move GNSS networks, obtain positioning information from these satellites to establish the device’s location on Earth. Device location accuracy depends on many factors such as:
- Clear view of the open sky, as barriers such as tall buildings, indoors, can interfere.
- How many satellites the device can see.
- How many GNSS networks the device is using.
- The capabilities of the device itself including how accurate it is designed to be.
- Antenna quality, device installation, update interval of the device and more.
Some devices will use a single network such as GPS, other devices may use two or more. Modern mobile phones often use multiple GNSS networks providing improved location services.
There are other location based systems that are available that do not use satellites.
