ZY-2 (Ziyuan-2, 'Resource-2'), while reported as a civilian Earth observation system, was actually code-named JB-3 (Jianbing-3) and was China's first high-resolution military imaging satellite. They are reportedly used for area surveillance.
Polar OrbitCluster is an magnetospheric research project, consisting of a constellation of four identical satellites. Part of the first Cornerstone Mission in the European Space Agency's long-term space science programme, the Cluster II satellites were built to replace the original Cluster mission, which was aborted after Ariane-5G's maiden flight in June 1996 failed to launch the satellites. The mission's objective is to research the Earth's magnetosphere and its interaction with the solar winds, via four identical satellites flying in formation which take simultaneous measurements to provide the most detailed three-dimensional study of changes and processes taking place in near-Earth space. The four satellites were launched in 2000 on two Soyuz-U Fregat rockets.
Elliptical OrbitPAS-9 was one of three HS-601HP satellites ordered Oct. 12, 1998, from Hughes Space and Communications Company (HSC) by PanAmSat Corporation. The satellite provides broadcast and general communications services in C- and Ku-band for the Americas, the Caribbean and western Europe, plus direct-to-home services for Mexico in Ku-band.
