RAIM with Multiple Faults

Contemporary Receiver Autonomous Integrity Monitoring (RAIM) algorithms such as that developed by Brown and Chin [1] are designed to allow the user's receiver to supply its own integrity and protect against the development of excessive noise as well as bias, both originating from the ranging measurements. Past RAIM protection levels have assumed that there is at most one ranging source with bias. This work is focused on extending RAIM protection levels to account for multiple biases.
