What is GNSS?

GNSS (Source: NASA)GNSS stands for global navigation satellite system and refers to a constellation of satellites, which provide signals from out of space for positioning. A GNSS has global coverage. There are several GNSS systems: GPS (United States of America), Glonass (Russian Federation), Galileo (Europe) and Beidou (China).
