Шаблон:Short description Шаблон:Infobox spaceflight DLR-Tubsat (a.k.a. TUBSAT) was a German remote sensing microsatellite, developed in a joint venture between Technical University of Berlin (TUB) and German Aerospace Center (DLR). TUB was responsible for the satellite bus and DLR was responsible for the payload.[1] The satellite was launched into orbit on 26 May 1999, on the fifth mission of the PSLV program PSLV-C2. The launch took place in the Sriharikota Launching Range.[2][3] The satellite had an expected life of one year.[4][5][6]
Mission objectives
The prime objective of DLR-Tubsat was to test the attitude control system (S/C attitude recovery from hibernation). The secondary objective of the mission was to test a TV camera system for disaster monitoring with the goal of the introduction of an interactive Earth observation concept, where the target is not identified in advance, a search action may be involved, or a particular target region has to be followed visually from orbit.[1][7][4]
