What is the definition of GNSS?

Stands for global navigation satellite system. A GNSS consists of a constellation of satellites orbiting the Earth in specific trajectories. The satellites provide orbit information and accurate timing to radio receivers designed to receive and decode the signal message contents. With the contents of the messages from at least four “visible” satellites, the position on or near most of the Earth’s surface can be calculated using a mathematical process known as trilateration.
