Book Description
The Topside Ionosphere Plasma Monitor (SSIE) is an operational system flown on the Block 5D F2 DMSP Satellite for transmission of continuous data on the state of the topside ionosphere. The instrument consists of separate electron and ion sensors mounted on a 2.5-ft boom deployed after spacecraft attitude has been stabilized in orbit. This report describes the two sensors, associated electronics, and their operational timelines. The theoretical basis is given for the measurement of a number of plasma parameters: electron temperature and density, ion density, average ion temperature and mean ion mass (for one or two ion species), spacecraft potential, and plasma scale height. (Author).

Book Description
The Topside Ionospheric Plasma Monitor (SSIE) has been successfully flown on the Block 5D DMSP satellites on Flight 2 and Flight 4. This report describes the value and the limitations of these data based on an analysis of in-flight data. The SSIE is useful for determining the relative variation of the plasma density along the orbit of the satellite on a nearly continuous basis from August 1977 to February 1980. Variations in plasma density due to daily and seasonal changes in the ionosphere can be determined. Variations due to geomagnetic storms and substorms can also be determined. The instrument is limited during daytime operations by a large negative potential caused by the solar panels. During daylight operations, thermal ions are accelerated toward the ion sensor and thermal electronics are deflected away. On F4, a series of four floating bias potentials between the instruments and the spacecraft ground was installed and has proven successful. These bias potentials will be used for SSIE instruments on Flights 5 through 7. Additional design changes for Flights 8 through 10 are discussed. A format for archived data types for Flights 5 through 7 is described.
