The UOSAT h.f. beacons experiment
Abstract
The University of Surrey amateur scientific satellite, UOSAT carries a set of phase related beacons on 7, 14, 21 and 29 MHz enabling experiments to be carried out into trans-ionospheric propagation at the four frequencies. The beacons, which deliver 100 mW each, are synthesized from the 7 MHz master oscillator and combined into one of two 2.5 m monopoles tuned against the satellite body and 15-meter boom. Modulation is by on/off carrier and can be routed from the telemetry system or the primary spacecraft computer.
