An experimental work is presented to examine a previous analysis for the estimation of positive ion density in the ionosphere from the ion current obtained by a rocket-borne Langmuir probe. The plasma was formed in a low- density supersonic wind tunnel, where the probe characteristics were measured. The drift Mach number, pressure, and temperature of the plasma were 3, 86 microns Hg, and 107 deg K respectively. It is indicated that the values of positive ion density estimated by the previous analysis are nearly equal to the values of electron density obtained from the electron saturation current characteristics that are considered to be almost independent of the supersonic drifting of plasma.
