Do you need to do a RAIM check on Waas?

So If you have a TSO C146 WAAS receiver there is no requirement for a RAIM check unless again it fails. The WAAS system monitors the GPS satellites with approximately 35 ground stations and calculates correction data as well as integrity data.

How is RAIM used in satellite navigation equipment?

Receiver Autonomous Integrity Monitoring (RAIM), where only GNSS information is used. RAIM scheme can be included in the satellite navigation airborne equipment, either as the main source of integrity or as a back-up for alternative sources, e.g. SBAS.

How does Waas work and how does it work?

The GPS information collected by the WRS sites is transmitted to WAAS Master Stations (WMS). The WMS generates a WAAS User Message every second. These messages contain information enabling GPS/WAAS receivers to remove errors in the GPS signal, allowing for a significant increase in location accuracy and integrity.

What is the difference between GNSS and Raim?

Airborne Autonomous Integrity Monitoring (AAIM), where GNSS information is complemented with on-board sensors and other components. Receiver Autonomous Integrity Monitoring (RAIM) can be defined as a user algorithm that determines the integrity of the GNSS solution.
