Ries" Subject: Topex thrusting Cc: ahmed.h.salama@jpl.nasa.gov Content-Type: text/plain; charset="us-ascii" ; format="flowed" X-Virus-Scanned: by amavisd-new at csr.utexas.edu X-Validation-by: feissel@ensg.ign.fr Hi Everyone, It has come to our attention that there were thruster tests on Sept 23 and 24 on Topex. We still do not know the exact times. I hope we will see an updated SATATT file. However, this probably explains the anomalies, and may also explain the sparser SLR data. This was handled very badly by the Topex project, in my opinion. No advance warning, but worse, no mention of it after the fact. This has wasted our time and probably impacted the amount of SLR tracking. For geodetic work, you may wish to simply ignore these days from Topex. Regards, John
