PROSPECTS OF USING FREE SOFTWARE FOR GNSS MEASUREMENTS POST-PROCESSING
Opportunities of free software application for GNSS post-processing are discussed in the artcile. The comparisons 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.
