RTK and PPK Solutions with a Short Baseline Assisted with Random Sample Consensus

Abstract

The integration of Time-Differenced Carrier Phase (TDCP) with RANdom SAmple Consensus (RANSAC) into a generic RTK/PPK architecture is presented in this work. The traditional pre-filtering and validation stages of RTK/PPK will be assisted with outcomes from a RANSAC/TDCP solution computed at the rover receiver. The proposed architecture has been demonstrated with a PPK solution using measurements recorded with low-cost multi-GNSS receivers that are processed with an open-source, open-interface software receiver package.
