High Frequency Beacon

NSSDCA ID: 1981-100B-04

Mission Name: UOSAT 1
Principal Investigator:Dr. C. W. Smithers


The objectives of this experiment were the investigation of trans-ionospheric propagation of HF radio signals and the measurement of ionospheric electron column densities by phase-referenced observations at multiple frequencies. The instrument transmitter radiated up to four phase-referenced HF signals simultaneously. These signals were all synthesized from the same oscillator using frequency division techniques. The approximate frequencies chosen for the experiment were 7, 14, 21, and 28 MHz.
