Abstract:
Opportunities of free software application for GNSS post-processing are discussed in the article. The comparison of the performance of different examples of commercial and free software for GNSS Post Processing in relative and PPP kinematic and static modes are given. Free software is presented by RTKPOST which is a part of RTKLIB. Commercial software used for experiments was Magnet Office Tools, GrafNav and Justin. The experiments have shown that accuracies of static processing results obtained using commercial software, free open source RTKLIB software and free of charge online processing service CSRS-PPP are comparable. The best processing results in PPP kinematic mode have been obtained using online service CSRS-PPP. Processing of trajectory data using RTKLIB in PPP kinematic mode has shown significant deviations from etalon trajectory, which is, apparently, connected with high frequency of GNSS measurements data in observation file. The detected deviation is up to 1.5 m while data logging frequency is 5 Hz. The conclusion has been made that free software and online services can be applied in practice for high accuracy positioning with certain limitations.
