Short summary
The SAR Copernicus Sentinel-1 satellites require a high orbit accuracy of 5 cm in comparison to external processing facilities. Orbit analyses showed discrepancies between the results of the two Sentinel-1 satellites being identical in construction. Follow-up estimation of GPS antenna offsets shows the sensitivity to different orbit and observation models. Consistent results may be achieved for both satellites when applying estimated antenna offsets considering self-shadowing assumptions.
