RAIM stands for?

RAIM is the receiver’s own ability to check the integrity of GPS signals. It stands for Receiver Autonomous Integrity Monitoring, meaning the monitoring is built into the GPS receiver itself (not done remotely) and it uses the redundancy of available satellite measurements to detect and sometimes exclude faulty signals. This self-contained integrity check helps determine whether the navigation solution is trustworthy before it’s used for navigation. The other phrases would imply monitoring is remote, radio-based, or radar-based, which isn’t what RAIM represents.
