BeeSat-1
German satellite
BeeSat-1 or Berlin Experimental and Educational Satellite 1, is a German satellite operated by Technische Universität 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 kilometres (449 mi), a perigee of 714 kilometres (444 mi) 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 as of January 2011 it is still operational.
Begin with the source’s own compact description: “BeeSat-1” is german satellite. The dossier treats that line as a proposition to test through BeeSat-1, German and satellite, not as a finished interpretation.
Why this record matters
The phrase “german satellite” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 12, 2025. The linked authority identifier is Q813973. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009 and 2011.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
