RAIM stands for what?

Explanation:
RAIM is a capability of GNSS receivers that checks the trustworthiness of the satellite signal data on its own. It stands for Receiver Autonomous Integrity Monitoring. The idea is that the receiver uses multiple satellites to test for inconsistencies; if one satellite appears faulty, the receiver can exclude it and still provide a reliable position. This autonomy in integrity checking is what makes RAIM valuable for safety-critical navigation, especially in aviation, where knowing you have a trustworthy fix is essential. The other terms describe different systems or sensors (remote monitoring, radar-based checks, or altimeter monitoring) and are not the GNSS receiver’s self-check mechanism.
