BeeSat-1

BeeSat-1 or Berlin Experimental and Educational Satellite 1, is a German satellite operated by the Technical University of Berlin. The spacecraft is a single unit CubeSat, which was designed to test systems intended for use on future spacecraft, including a new design of reaction wheel. It has also been used for amateur radio, and is equipped with a small camera.

BeeSat-1 was launched by a Polar Satellite Launch Vehicle, serial number C14, flying in the Core Alone, or PSLV-CA, configuration. The launch took place from the First Launch Pad at the Satish Dhawan Space Centre, at 06:21 UTC on 23 September 2009. BeeSat-1 was a secondary payload aboard the rocket, which deployed the Oceansat-2 satellite. Five other secondary payloads were flown aboard the rocket; SwissCube-1, UWE-2, ITU-pSat1, Rubin 9.1 and Rubin 9.2.

BeeSat-1 is operating in a Sun-synchronous orbit with an apogee of 723 km, a perigee of 714 km and 98.4 degrees of inclination to the equator. It has an orbital period of 99.16 minutes. BeeSat-1 was designed to operate for at least twelve months, and it is still operational.
