Plasma Analyzer for Measuring Spacecraft Floating Potential in LEO and GEO
This paper describes the proposed Plasma Analyzer for Space Science (PASS) in detail. It also discusses geometric factor and energy resolution, and presents a comparison of the proposed PASS instrument to an instrument that has been used to measure spacecraft floating potential in GEO.
