GNSS

GNSS

A satellite navigation or satnav system is a system of satellites that provide autonomous geo-spatial positioning with global coverage. It allows small electronic receivers to determine their location (longitude, latitude, and altitude) from autonomous (several meters) to higher precision (cm. or better) using time signals transmitted along a line of sight by radio from satellites. The signals also allow the electronic receivers to calculate the current local time to high precision, which allows time synchronisation. A satellite navigation system with global coverage may be termed a global navigation satellite system (GNSS), as this uses multiple satellite constellations. Systems like GPS (US based NAVSAT), GLONASS (Russian), Galileo (EU), Beidou (China), and others. We refer to this technology as GNSS and not GPS as this term covers all the various capabilities of the technology on the market today.
