摘要： A self-contained fueling module (10) provides the exact amount of hydrazine necessary to fuel a satellite (50) prior to launch. The fueling module (10) includes a propellant tank (14), a vacuum tank (12) and a pressurant tank (16). The propellant tank (14), filled with hydrazine, is shipped to the launch site where it is installed in the fueling module (10). Prior to launch, the fueling module is connected to the satellite and hydrazine is driven with Helium pressurant into the satellite fuel tank (52). The Helium also pressurizes the satellite fuel tank (52) to flight pressure. Any remaining fuel is evacuated from connection (45) and fuel transfer lines (42) with the vacuum tank. Personnel do not have to wear self-contained atmospheric pressurized environment (SCAPE) suits because there is no risk of hydrazine exposure.
