TopSatとは 意味・読み方・使い方

TopSat (Tactical Operational Satellite) is an Earth observation satellite that was launched on October 27, 2005 alongside the Beijing-1 Disaster Monitoring Constellation satellite by a Cosmos rocket from Plesetsk Cosmodrome in Russia. TopSat carries out imaging with a ground resolution of 2.5m. Much smaller and cheaper than other imaging satellites of similar high resolution, TopSat has been used to demonstrate the feasibility of providing images on demand to portable groundstations, such as might be deployed by the military or by disaster relief organisations.
