Abstract: A post-processed GNSS solution from raw GNSS data acquired from a vehicle and optionally other sources is dynamically calculated at the epoch level without using a Kalman filter. Instead, a plurality of GNSS processing methods is applied to each epoch in either the forward or backward direction and the most accurate solution for each epoch of the forward generated solution and backward generated solution is combined. The combined post-processed GNSS solution is determined based on which of the GNSS processing methods were used to generate an epoch of the forward solution and a corresponding epoch of the backward solution.

Abstract: Systems and methods for static session multipath detection are described herein. In certain embodiments, a system includes one or more global navigation satellite system (GNSS) receivers configured to receive GNSS signals from multiple GNSS satellites, wherein the GNSS receiver provides GNSS measurements. The system also includes one or more processors configured to receive the GNSS measurements.

Abstract: Systems and methods for GNSS ambiguity resolution are described herein. In some examples, the systems and methods utilize multiple search engines in parallel to validate potential integer candidates for ambiguity resolution using adaptively adjusted residual thresholds.
