These batteries showed good performance as the main power source of the satellite during eclipse, which solar power isn't available. The satellite, which was launched by H-2A Launch Vehicle No. 2 (H-2A F2) on February 4, 2002, has ended its one year and eight months onorbit mission, which was much longer than the scheduled mission period of a year, and acquired various data. On September 25, 2003, the command signal was sent to stop radio frequency (RF) emission from the satellite. In this paper, orbital performance of these Ni-MH batteries on MDS-1 is reported., 資料番号: AA0048057018, レポート番号: JAXA-RM-04-010}, title = {MDS-1バスバッテリの軌道上評価}, year = {2004} }
