Launch: 
6 October 1981 at 11h27 UTC,
from Vandenberg Air Force Base's SLC2W, by a Delta 2914 (Delta 2310 639
/ Delta 157). 
Orbit: 
538 km x 541 km x 97.46° 
Decayed: 
13 October 1989 
Mission: 
Built by the University of Surrey, UO9 was
UoSAT's first experimental satellite. It was a scientific and educational
lowEarth orbit satellite containing many experiments and beacons but no
amateur transponders. UO9 was the first amateur satellite to carry an
SBand beacon. UoSAT 1 weight 52 kg and was boxshaped (740 x 420 x 420
mm) with a deployable gravity gradient boom. It was fully operational until
it reentered after nine years of service.

Orbit: 

Decayed: 

Mission: 
RS5 contained Mode A linear transponders.
It also contained "autotransponders" called ROBOTS. These ROBOTS made it
possible to carry on a CW telegraphy contact with the spacecraft. A typical
communication with the ROBOT would be initiated by the radio amateur on
the ROBOT uplink frequency and the satellite would respond with a short
message and issue a QSO number.
