Abstract:
1. A processor-implemented method of estimating a position of a navigator, the method comprising: receiving, from at least one sensor, measurements of the position of the navigator, the measurements being corrupted by compressible non-Gaussian noise; determining an estimated compressible non-Gaussian error at least in part by determining a basis in which the compressible non-Gaussian noise is compressible based on state information of a dynamic state estimator and the measurements; generating corrected measurements of the position of the navigator based on the estimated compressible non-Gaussian error and the sensor measurements; and estimating the position of the navigator based on the corrected measurements at least in part by providing the corrected measurements as an input to the dynamic state estimator and running the dynamic state estimator with the corrected measurements.
