Abstract	:	The in situ measurement of ionospheric plasma density is important because of theionosphere's effect on both earth and space systems. The plasma impedance probe (PIP)is a useful plasma diagnostic tool for determining absolute and relative electron densities,magnetic field strength, and electron-neutral collision frequency. The PIP is a suite ofinstruments including a plasma frequency probe (PFP), a swept impedance probe (PSP),a plasma Q probe (PQP), an experimental ion impedance probe (IRP), and a DC Langmuirprobe (DCP). This thesis presents at a system level the design of the PIP and its functions.The digital control system for the instrument is described in detail and modeled using thesirnulink@ software package. Finally, PIP data that was collected from a series of soundingrockets launched in the summer of 2003 is analyzed to determine the performance of theinstrument.(101 pages).............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
