Receiver autonomous integrity monitoring (RAIM) is a technology developed to assess the integrity of GPS signals in a GPS receiver system. It is of special importance in safety-critical GPS applications, such as in aviation or marine navigation.
Fortunately, most GPS units automatically provide the correct level of RAIM along those routes, but some older GPS units need to be forced into terminal (1.0nm RAIM) mode for departures. When you must perform RAIM PREDICTION is a separate question (and probably what you were originally asking).

Integrity and RAIM . Before WAAS was introduced you were required to do an integrity check before each flight when you planned to navigate with a GPS receiver certified under TSO C129 (supplemental navigation). Each such certified GPS receiver must be able to perform a check of the integrity of its position solution.
Satellites can be manually deselected or enabled for destination and alternate waypoint predictions. The approach area RAIM prediction is an output of current RAIM projected 5 min into the future. Approach area RAIM is a continuous output that is performed without any interaction with the FMS.

5/21/2014 · My understanding is that the RAIM check within the GPS uses it's onboard almanac to predict if a suitable number of satellites will be available at the time and place specified, whereas the NAIPS RAIM check incorporates other real time information such as satellite health and serviceability to provide a RAIM prediction.
Remarks: All the IFR-certified GPS unit will do RAIM check 2 NM prior to reaching FAF. So during flight we do not need to. As long as we have performed prediction throughout the route. We will know whether to avoid that airport's RNAV approach, just in case prediction says 5+min of RAIM service might not be available for some part of leg.

What's RAIM? RAIM stands for Receiver Autonomous Integrity Monitoring.It is a form of integrity monitoring performed within the GPS receivers themselves. It ensures available satellite signals meet the integrity requirements for a given phase of flight.
RAIM prediction. GPS differs from traditional navigation systems because the satellites and areas of degraded coverage are in constant motion. Therefore, if a satellite fails or is taken out of service for maintenance, it is not immediately clear which areas of the airspace will be affected, if any. The location and duration of these outages ...
If I’m flying a GPS approach and I have a RAIM failure, I should stop the approach and go missed. I’m getting a bit confused on WAAS. So with a TSO-C145/146 WAAS GPS, I don’t need to perform a RAIM prediction unless my route of flight will be out of WAAS coverage.
