Baseline Advanced RAIM User Algorithm and Possible Improvements

You are here

We present a baseline multiple fault and multi-constellation Advanced RAIM user algorithm for vertical guidance.  After reviewing the navigation requirements for LPV-200 approaches, we describe in detail how to process the pseudorange measurements, the nominal error models, and the prior fault probabilities to obtain the protection levels and other figures of merit.  In particular, we show how to determine which fault modes must be monitored, and a method to perform fault exclusion. Finally we present a list of possible algorithm improvements and simplifications.
