STUDY ON LIPS-200 ELECTRIC PROPULSION SYSTEM CONFIGURATION ON GEO SATELLITE BUS

A configuration solution of electric propulsion system based on LIPS-200 thruster is put forward on GEO satellite bus,which could be applied to NSSK mission for GEO satellites if payloads need.The solution can meet all the AIT requirements such as units mounting,pipes welding,thermal implementation,system leak detection and ground tests,etc.It had been verified on bus's electrical model and structural model.In addition,with the same launch mass and serving life,satellites assembled with the LIPS-200 electric propulsion system can load about 42.8%more payloads in mass than the satellites that with only chemical propulsion system.Then,it is more economical.
