DLR-Tubsat (a.k.a. TUBSAT) was a German remote sensing microsatellite, developed in 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. 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. The satellite had an expected life of one year.
The prime objective of DLR-Tubsat was to test attitude control system (S/C attitude recovery from hibernation). The secondary objective of the mission was to a TV camera system for demonstrate disaster monitoring with a goal of 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.
