ATS-6 radio beacon experiment

Abstract

SINCE ATS-6 was launched into a geostationary orbit at 94°W in late May 1974, measurements of the total electron content (TEC) using the Faraday polarisation-rotation1 and group dispersive-delay techniques have been made at Fort Monmouth (40.18°N; 74.06°W). Comparison of TEC rate of change obtained by the two techniques yields the temporal variation of the integrated number of free electrons above the ionosphere. This variation indicates a flow of electrons from regions above the ionosphere into the ionosphere at night, while during the day the direction of flow is reversed. The rate of the electron flux is estimated using the continuity equation.
