GLONASS-Only Analysis

Figures and Statistics from the IGS Ultra-Rapid GLONASS Orbit Combination

Orbit combination comparison figures

The plots below show the Weighted RMS and Median differences (mm) of the individual AC orbits with respect to the IGS ULTRA-rapid GLONASS products. The comparisons are performed over the entire 48 hours of the products.

Orbit transformation results per AC

The next plots show the weekly averages of the Helmert translation, rotation, and scale parameters of the individual AC solutions with respect to the IGSULTRA-rapid products.
