UoSat-OSCAR 9
Encyclopedia
UO-9 was an amateur satellite
built at the University of Surrey
and launched into low Earth orbit
on 6 October 1981. It exceeded its anticipated two-year orbital lifespan by six years, being received on 13 October 1989 before re-entering the atmosphere. Like its successor UoSAT-2
it carried a CCD camera and a Digitalker speech synthesis
er, and transmitted telemetry data on a 145.826 MHz beacon at 1200 baud using asynchronous AFSK. The Astrid package sold by British firm MM Microwave, consisting of a fixed frequency VHF receiver set and software for the BBC Micro
, could display the telemetry frames from either UoSAT-1 or UoSAT-2.
UoSAT-1's solar arrays were of an experimental design reused for UoSAT-2.
Satellite
In the context of spaceflight, a satellite is an object which has been placed into orbit by human endeavour. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon....

UO-11
UO-11 is an amateur satellite built at the University of Surrey and launched into orbit on 1 March 1984. It remains orbital and active, though unstable with irregular periods of transmission. The satellite was still heard transmitting telemetry in December 2010, more than twenty-six years after...
