A fixed-frequency ionosphere satellite, explorer (Roem.) 20, was developed for the purpose of obtaining pulsed soundings of the topside of the ionosphere. the basic sounder instrumentation comprises a two-frequency transceiver coupled to an electrically short dipole antenna. Three transceivers were used for sounding at six frequences between 1.50 and 7.22 mhz. A two-frequency sounder playload was developed for initial rocket testing to demonstrate the feasibility of topside sounding and to provide design data for both u.S.A. and canadian topside-sounder satellites.
