ESOC Precise (SLR+DORIS) vs. CNES Precise Orbit Comparison

The CNES precise orbit used in this comparison is the final precise orbit for Envisat which is used on the GDR Altimeter product. These orbits are generated by CNES with a latency of 6-9 weeks. The radial accuracy of this orbit is around 3 cm see orbit comparison campaign.

The following plot shows the along-track, cross-track and radial components of the comparison between the CNES precise orbit and the ESOC precise orbit.
