Download ERS-1 fast-delivery (DGM-E04) orbits

Fast-delivery orbits are available from 18 June 1999 until the end of life (12 March 2000). .

DEOS fast-delivery ERS-1 orbits are based on the DGM-E04 gravity field model and SLR normal points. These orbits are generated each Tuesday and Friday afternoon based on the latest SLR data.

The orbits can be downloaded from the DEOS or NOAA ftp servers. The orbits are stored as separate ODR files. Downloading of these files by normal FTP is more practical if you experience bad connections.

Please acknowledge the fact that you have been using the orbits of the Delft Institute for Earth-Oriented Space Research in any publication that is the result of it.
