Abstract
Measurements of cosmic radio noise made from the satellite 1960 Eta 1 at a frequency of 3.8 Mc/s have been reported. The major effect of the ionosphere on the measurements are two. First the field strength at the antenna is a function of the radiation resistance of the antenna. Second, the region of the sky from which radio noise is received is restricted by ionospheric refraction. It is shown that values of the electron density about the satellite can be inferred from the measurements.
