Updated Precise Orbit data (POD) for the full ERS-1 and ERS-2 mission available online
12 July 2019
The Precise Orbit files (ERS.ORB.POD) for the entire ERS-1 and ERS-2 mission periods have been reprocessed with up-to-date standards and is now available to users on the ESA dissemination server upon fast registration.
The new standards significantly improve all POD metrics, and careful validation of the various solutions has shown that the Delft University of Technology orbit (DEOS solution) has the best performance for both missions. See the ERS Orbit Validation Report for further details.
The main new standards applied:
In addition, the new solutions are covering the full mission period for ERS-2, i.e. the period from June 2003 to July 2011 is taken into account as well. The latter results in orbit solutions covering respectively:
Note that also the latest version of the Envisat Precise Orbit data (POE or DOR_VOR_AX) generated with the GDR-E standards is available from the ESA dissemination server upon registration.
