Abstract
A method and system for determining a receiver position comprising receiving satellite observations from a set of satellites, determining differenced observations based on the satellite observations, determining an all-in-view position of the receiver based on the differenced observations, determining a set of fault modes each associated with a subset of the differenced observations, for a fault mode of the set of fault modes, determining a fault-tolerant position of the receiver using the subset of differenced observations associated with the fault mode, when the all-in-view position and the fault tolerant position of the receiver for each fault mode are within a solution separation threshold, calculating a protection level associated with the all-in-view position of the receiver.
