Multitask Mode Electric Propulsion Technologies

The applications of multitask mode electric propulsion technologies in GEO satellites and deep space probes are introduced, and the electric propulsion technologies are used from single task mode of north/south-station keeping of orbit to multitask mode of north/south-station keep- ing of orbit and orbit-transfer. The functions of multitask mode electric propulsion technologies such as power demand, specific impulse, and thrust are summarized. Key techniques for multi- task mode electric propulsion technologies are discussed, including satellite platform, thruster, conversion and control of variable power supply, variable flow adjustment, and adjustment of multi-freedom and large angle vector.
