ERS and Envisat Precise Orbit Determination: Tools and Software
Last update: 13 Aug 2004
The orbits provided by DUT/DEOS are stored in a binary format. This
reduces the file size and speeds up the loading of the file for
processing. Unfortunately, if makes the files less accessible to read.
To make life easier, we provide several utilities, in a software package
and as on-line utilities.
- Getorb package
- This package contains several utilities to handle the Delft orbit
files. Programs to list, interpolate the orbits, and do date
conversions. A subroutine is
available to incorporate the interpolated orbits into your own software.
- Getorb utility
- On-line request for the position of ERS-1 and ERS-2 for any
given period. Specify start time, step size, and period.
Interpolated position are return, in geodetic and/or geocentric
- Convdate utility
- The orbits are time tagged in SEC85 (seconds after 1.0 January 1985,
a Geosat GDR heritage). Convert between YYMMDD, MJD and SEC85 with this
