• The swept frequency impedance probe IPS, which is designed to measure ionospheric plasma parameters, has been installed on the REXS-DENPA satellite (1972-064A). The IPS consists of an impedance measuring equipment, automatic sample-detection sub-systems and 2m antenna as a sensor immersed in space plasma. The impedance measuring equipment is known as the gyroplasma probe. Various plasma resonance frequencies are detected and antenna impedance values at several frequencies are measured. Those digitalized data are fed to PCM telemetry through a data sampling system. The pre-flight operation and plasma-simulation tests were found to be satisfactory; they provided, also, the calibration data on equipment characteristics at different temperature values that can be realized in the flight condition. The REXS was successfully put into the orbit on August 19,1972. Measurements of ionospheric plasma parameters, such as electron density and ion composition were made in the altitude range from 240km to 6570km over the equatorial orbit (inclination 31°). Observational data have been analysed applying the data handling method aided by digital computers. Preliminary results obtained for a period of three-days observation are summarized for following items; i) electron density profiles in the topside ionosphere over the sub-tropical latitudes, ii) mean ion composition in the topside ionosphere and iii) the antenna potential control effect due to photomission from metalic antenna surface.
