You can get RAIM forecasts from a receiver (or the simulator). It
knows where all of the satellites are located at any time in the
future. If you provide a location to the RAIM and a time to the RAIM
prediction screen, it will tell you if the satellite geometry will
give you satisfactory reception.


Immagine that every pair of satellites with you as the third point defines
circle. When multiple circles line up, there is not enough time difference
to make a calculation. The signal is unaffected.
