  • Post-processing global navigation satellite system (GNSS) position data using mirrored GNSS data
    Patent number: 11156722
    Abstract: A post-processing system providing forward processing (FP) of original GNSS raw data and alternative forward-backward processing (BP) of modified GNSS raw data and combining results of the FP and modified BP to enhance accuracy of position data derived from GNSS raw data. The post-processing system includes a GNSS processing engine, such as a real-time PVT engine, that processes GNSS raw data files as real time data streams equally for FP and BP. The backward processing is performed on a set of GNSS raw data that is mirrored from the original GNSS raw data. The modified BP uses the same algorithms of the PVT engine in a forward run but with the mirrored GNSS raw data to provide BP including position estimate with associated accuracy estimates for each data epoch. A forward/backward combiner combines results of the FP and the modified BP to provide final position data with enhanced precision.
