Satellites in Geostationary Orbit for long-duration missions in excess of 5 years encounter perturbations to their trajectories over time. These spacecraft perform maneuvers periodically to compensate for drift and orbital decay called "station keeping" maneuvers.

An electrothermal rocket engine is method of propulsion by which an inert gas stored at ambient temperature (cold gas) is released from a pressurized vessel or driven by a pump and heated electrically before being expelled out of a nozzle. Two proven methods of electrothermal propulsion are "resistojets," which use conventional heat exchangers to heat the propellant, and "arcjets," which pass the propellant through an electrical arc to heat the gas.

This type of propulsion system is advantageous for use by long-life satellites since the engines may be small in size, have few moving parts, and do not use combustible fuels. Resistojet and arcjet engines produce less thrust than chemical rocket engines, but are more efficient, do not require ignition, and are easy to store for long periods.
