Abstract: A Time-Differenced Carrier Phase (TDCP) with RANdom SAmple Consensus (RANSAC) can be integrated into the generic RTK/PPK architecture. It can be used to pre-select satellites to be excluded, and to validate an RTK/PPK solution after integer ambiguity is resolved. The proposed architecture has been demonstrated with a PPK solution using two types of low-cost multiconstellation receivers. The software implementation is based on RTKLIB, an open-source, open-interface software receiver.
