Micro-Pulsed Plasma Thrusters (PPT) are becoming increasingly
attractive for their low power consumption and moderately high
specific impulse from 800-1000s. The Gatling Gun micro-Pulsed
Plasma Thruster (GG-PPT) is a new device offering reduced mass and
higher thrust than single PPTs in precise pointing and orbit
maintenance applications. The performance of PPTs depends on
frequency and applied voltage/power levels. A variation of these
input parameters and effects on operation and performance of this
thruster system will be the focus of this research. Contamination
aspects will also be considered, since the buildup of carbon
results in decreased life for these thrusters. The goal is to match
the frequency and power input to avoid this operating condition.
