PHASE MODULATION IN LOW POWER TELEMETRY. (LA MODULATION DE PHASE EN TELEMETRIE DE BASSE PUISSANCE).
Abstract
Studies were made of the upper atmosphere using Black Brant rockets launched from Churchill Research Range on the Hudson Bay. Ion density and electron temperature inside auroral plasmas are determined. Collected data are transmitted to earth by a radio-telemetry link. It is found that for precision measurement the power of the radio trnasmitter must be reduced to limit the electromagnetic field around the probe. The problem then is to construct a high quality telemetry network between the probe and the terrestrial station.
