Abstract: Reconfiguration technique is developed for advancing the reliability of unified propulsion subsystem (UPS) of navigation satellite in failure mode. The UPS can be recombined through this technique, and the damage to 10N thrusters can be isolated. This report describes the principle of the reconfiguration technique in several commonly used modes. The result can provide a reference for the followup design and fault counterplan for the UPS of navigation satellite.

Key words: navigation satellite, propulsion subsystem, fault state, reconfiguration technique
