“…The small impulse bits (I bit ) (produced specially by rail-type PPTs) could prove advantegeous in precision pointing and constellation maintenance applications. 17 argues that with the increased interest in micro and nanospacecraft(addressed in section II), the ability of producing very small impulse bits at high enough I sp levels to keep acceptably low system-masses enjoys great interest today. When applied to attitude control systems(ACS), PPT brings significant mass savings over conventional torque-rods and momentum-wheel solutions, which potentially drove the PPT reinassance of the 2000s.…”

Since first launched in 1964 by the Soviet Union aboard Zond-2, Pulsed Plasma Thrusters (PPTs) have come a long way to currently enjoying the heritage of eleven successful flights and about fourteen active R&D laboratories around the world. Renewed interest in PPTs has been kindled by the growing microsatellite industry due to their performance at low powers, precise impulse bit, throttling capability, simplicity, and robustness. For the purpose of mission planning, the field of PPTs is plagued with various, often contradicting, naming schemes. It is imperative for the community to agree in a certain classification scheme. The present work presents a suitable classification to the immense variety of electrode geometries, feed-mechanisms, propellant state of matter, ignition-mechanism, and energy ratings . It was found PPTs could be classified via energy input in much the same way as microsatellites are classified according to their mass and power. Furthermore, an extensive PPT data base amassed over the years at IRS allows large-scale performance comparisons between PPT geometries and other EP technologies revealing important patterns for mission design.
