Electron density measuring instruments are one the most widely used class of space instrumentation. Two of the prime instrumentation techniques for measuring electron density are the Langmuir probes and Plasma Impedance Probes. While Langmuir probes are able to give higher resolution electron density and plasma temperature measurement, Plasma Impedance Probes give absolute electron density measurements irrespective of spacecraft charging. Over the last decade Utah State University has flown a number of Langmuir probes (both sweeping and fixed bias type), and Plasma Impedance Probes (dipoles, monopoles, and patch antennas) on sounding rockets with NASA. The various generations of these instruments have had variable degree of success and the lessons learned continue to help us improve their performance with innovative designs, miniaturization, and manufacturability. This paper shall talk about the various instrument designs flown, their performance and the geophysical results that the datasets have provided. In particular we emphasis the use of heated Langmuir probe sensors and novel patch antennas for impedance probes.
