Receiver autonomous integrity monitoring (RAIM) is a technology developed to assess the integrity of individual signals collected and integrated by the receiver units employed in a Global Navigation Satellite System (GNSS).

Dec 19, 2024 · Understand the differences between RAIM and WAAS, their roles in GPS accuracy, and why WAAS is the preferred choice for modern aviation.

Jun 21, 2021 · The color scale shows the duration of any RAIM outages anywhere in the world. The horizontal protection levels of the given service are listed next to each plot title.

Jul 27, 2023 · RAIM technology enables the aircraft’s receiver to assess the accuracy of the GNSS signals it receives. It compares multiple satellite signals, checks for any inconsistencies or errors, and determines whether the navigation solution is reliable.

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.

Jul 27, 2020 · RAIM (Receiver Autonomous Integrity Monitoring) is a technology that is used in GPS receivers to assess the integrity of the GPS signals that are being received at any given time.

Receiver Autonomous Integrity Monitoring (RAIM) provides GPS solution integrity without additional augmentation RAIM functions include Fault Detection (FD) and Fault Detection and Exclusion (FDE)

Garmin provides this free RAIM/FDE Prediction service to provide high quality prediction which takes into account the performance of Garmin GPS receivers.

Jul 22, 2021 · We’ve seen that RAIM is a statistical consistency test of multiple pseudorange measurements. Thresholds set too tight result in excessive false detections and exclusions, yielding poor usability.

GPS with Receiver Autonomous Integrity Monitoring (RAIM) has been used for aircraft navigation since the mid-nineties. Today, RAIM guarantees horizontal error bounds of one nautical mile worldwide with high availability.
