Microwave Beacon

NSSDCA ID: 1981-100B-05

Mission Name: UOSAT 1
Principal Investigator:Dr. M. N. Sweeting


Beacons at 2.4 and 10.47 GHz were used to demonstrate the feasibility of using the higher frequency bands in transponder applications for future amateur communications spacecraft and to encourage the development of relatively inexpensive microwave ground station equipment by amateurs. The spacecraft-to-ground transmission link budget was very marginal, and required considerable skill to overcome Doppler and azimuth-elevation tracking requirements.
