A TELECOMMUNICATIONS LINK MODEL FOR DEEP SPACE, WITH APPLICATIONS TO THE HELIOS PROBE

International Telemetering Conference Proceedings / October 10-12, 1972 / International Hotel, Los Angeles, CaliforniaThe concept of the coherent PCM/PSK/PM telecommunication system of the US/German solar probe mission HELIOS is presented. Subsystem performance models are given for the telemetry link using theoretical, simulation, and measurement results, to obtain a realistic approximation to the over-all link performance. After the system description, performance/ efficiency models are discussed for the (sequential) data decoder, symbol synchronizer, subcarrier and RF demodulation, and waveform distortion. The integrated over-all link model is then applied to minimizing the total signal-to-noise ratio requirement at receiver input. Examples from the HELIOS link design demonstrate the feasability of the approach.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
