Abstract

Described herein are systems, methods, and other techniques for detecting and removing GNSS observable outliers. GNSS observables are generated based on satellite signals received at a GNSS receiver. A first position estimate is computed for the GNSS receiver based on the GNSS observables. A set of code biases for the set of satellite signals are computed based on the first position estimate and the GNSS observables. A set of code bias deviations for the set of satellite signals are computed as a difference between, for each of the set of satellite signals, a code bias of the set of code biases and a code bias model of a set of code bias models. A set of code multipath error estimates are computed based on the set of code bias deviations. A statistical outlier is identified from the set of code multipath error estimates.
