Claim 0:
1. A computer implemented method of validating an output from a global navigation satellite system (GNSS), the method comprising:
receiving at a GNSS receiver including a fusion system an output from at least one satellite in the GNSS, the fusion system comprising one or more location sensors;
computing a GNSS location estimate input and a GNSS location error estimate input;
computing a navigation update with the fusion system based on sensor measurements from the one or more location sensors, wherein the navigation update includes a sensor location estimate and a sensor location error estimate;
determining when one or more GNSS filters are applied based at least on the GNSS location estimate input, the sensor location estimate, and the sensor location error estimate;
wherein when the one or more GNSS filters are applied, applying the one or more GNSS filters by adjusting or rejecting one or more of the GNSS location estimate input and the GNSS location error estimate input and computing a new navigation update with the fusion system based on the adjusting or rejecting of the one or more of the GNSS location estimate input and the GNSS location error estimate input; and
wherein when the one or more GNSS filters are not applied, computing the new navigation update with the fusion system based on accepting the GNSS location estimate input and the GNSS location error estimate input.
