Title: Photoemission based spacecraft charging sensor

Abstract: A charging sensor that uses photoemission to directly measure theelectrical potential of a spacecraft in orbit relative to the spaceenvironment. The photoemission based charging sensor uses photoemissionfrom a photoemitting conductive plate of a charge probe as a referencepoint for voltage readings and provides direct measurements of spacecraftcharging.
