Comparison of long-baseline results processed with different GPS software packages

The goal of this research was (1) to evaluate the effect of different GPS software packages on processing medium and long baselines (50 - 300 km), (2) to investigate the improvement of the results by using precise ephemerides, and (3) to derive more realistic measures of accuracy for each software. The following commercial software packages were investigated: GPSutvey ver. 1.20a (Trimble), GPPS ver. 5.2.0 (Ashtech), SKI ver. 1.09a (Leica), TOPAS-Turbo ver. 3.3a (terraSat) and the scientific software of Bern University (ver. 3.5) has been used as reference.
