Abstract
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.
