In the night of Dec 18(JST), we heard good News from Grasse LLR station. Grasse has succeeded in the laser ranging of LRE. Using these QLNP(about 7 hours), NASDA succeeded in the LRE orbit determination and already distributed new IRV (#43) to all stations. We think that this success will be good chance for continuous tracking at the other stations because the IRVs of LRE becomes very precisely than the past IRVs which is generated by NASA TLE. About for a week(the period of validity of NASDA IRVs), new IRV will keep high accuracy. You can see the detailed analysys result on the web, http://god.tksc.nasda.go.jp/lr/comp30.html We need more tracking support by many stations and we would like to improve IRVs. Your help will be much appreciated. with best regards, Maki MAEDA -- ============================================================ Maki MAEDA TEL:+81-298-68-2625 FAX:+81-298-68-2990 National Space Development Agency of Japan(NASDA) Office of Satellite Technology,Research and Applications Satellite Mission Operations Dep.
