Hi all! Some colleagues here at ESOC are preparing radar observations of ERS-1. Obviously, it not longer possible to do the usual obit determination. It is assumed that the frequent thruster firings before the end of the satellite had a massive impact on the orbit. It would be helpful to know how accurate the latest NORAD elements match the actual orbit. Please let us know if you can observe a time offset with respect to the predictions. Could somebody have a look? Informations about the lightcurve period would be helpful, too. ERS-1 1 21574U 91050A 00074.93506865 .00002107 00000-0 76790-3 0 451 2 21574 98.5493 150.3299 0036616 78.1343 306.8401 14.33762036453083 Thanks in advance, Rainer ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
