Pakistan's second satellite BADR-B was launched on 10 Dec 2001 at 9:15 a.m from Baikonour Cosmodrome, Kazakistan. The Zenit-2 rocket carried it
into a 1018 Km sun-synchronous circular orbit with an orbital period of 105 minutes and inclination of 99.64 degrees.

Configuration |
| |
The satellite structure was made of space qualified aluminum T-6 alloy. Gallium Arsenide (GaAs) solar arrays were used to provide power during the sunlit periods and Nickel Cadmium
(NiCd) batteries during the eclipse periods. Earth pointing single axis stabilization was achieved by use of a 6 m gravity gradient boom with a trip mass of 4kg. |
