The paper presents principles and performance of new on-line automatic system for GNSS data post-processing developed at the University of Warmia and Mazury in Olsztyn. The system allows for obtaining a precise position of the user receiver on the basis of faststatic and kinematic GNSS data. The system requires minimal user input. The user uploads RINEX data files collected with a GNSS receiver, the system carries-out all data processing, and the user gets back resulting coordinates via email. The internal software operates in static, ultra-fast-static and kinematic modes. The developed algorithms support combined processing of multi-GNSS (GPS+Galileo) and multi-frequency observations in a single mathematical model. The solution is obtained with respect to three neighboring GNSS reference stations (multistation solution) and takes advantage of precise tropospheric and ionospheric corrections. The system offers centimeter-level accuracy with baselines lengths of up to 100 kilometers.

Keywords: Global Positioning System (GPS); Global Navigation Satellite System (GNSS); precise satellite positioning; automatic GNSS post-processing software.
