NORAD gave word to Scott Wetzel that GFZ-1´s decay was complete at approximately 0100z on June 23rd, 1999. We from the GeoForschungsZentrum Potsdam (GFZ) would like to thank the SLR community for all the strong and engaged support being given to this mission by the stations, data centers, and institutions. As we heard from various sides, the mission is looked upon as being a quite successful one. For the SLR technique GFZ-1 was quite a challenge due to its extremly low altitude. In view of new exciting LEO missions to come, GFZ-1 can be assigned a kind of pathfinder mission for new SLR horizons. Also the scientific outcome has been given proof. GFZ-1 data contribute to the solution of coefficients of a spherical harmonic expansion of global gravity field models up to degree 100 at resonant orders which means a considerable increase in gravity field knowledge. In addition GFZ-1 data challenged POD with its surface forces environment. Lately GFZ-1 data have been used to calibrate and check orbital decay analysis. We are proud and honored to send this message and look forward into the next century with fascinating new lessons to learn. Thank you all again and our very best regards Chris Reigber, Head of Project Rolf Koenig, Technical Manager From: Rolf.Koenig@dlr.de (Dr. Rolf Koenig) ******************************************************************************** |
