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 IGS
ULTRA-rapid products.
Plots for the individual AC solutions with respect to the IGS ULTRA-rapid products.
The translations are shifted by 50 mm. The rotations are shifted by 2 mas.
