5. Position calculation
In reality, GNSS offers much more than just position calculation. The complete navigation solution is called "PVT" for position, velocity and time. We'll come back to position and show how the "time" aspects are included. We'll look at two calculation methods and then move on to the case of speed.
5.1 Position, speed and time
5.1.1 Principle of distance measurement
The basic principle is to measure the distances between the satellites and the receiver. We have seen that the intersections...
