For non pilots, RAIM is an indicator that the GPS has a redundant solution that matches the barometrically measured altitude.
I know this is off topic, but I don't like to let incorrect information float around uncorrected.
RAIM never uses any data outside of GPS to confirm position, it is based entirely on more than the minimum number of satellites needed for a basic position to calculate redundant solutions, which means a minimum of 5 satellites.
If this were not the case, it would be impossible to get a RAIM "prediction" (using data about out of service sats) in advance of a flight.
