ABSTRACT:
A system, a portable propellant loading tank and loading method for bipropellant spacecraft servicing to load propellant into a spacecraft. The spacecraft has a propellant storage tank with a propellant input and a vent output. The system comprises a portable propellant loading tank for storing and transferring propellant that is couplable to the propellant input of the propellant storage tank in the spacecraft. The propellant loading tank is a stainless steel tank that is electropolished on its interior surface. A portable weighing system having a plurality of load cells provides output signals indicative of the weight of the propellant loading tank. A load cell readout device is coupled to the portable weighing system for providing an output indicative of the weight of the propellant storage tank. A receiver tank is coupled to the vent output of the propellant storage tank in the spacecraft. A second weighing system having a plurality of load cells provides output signals indicative of the weight of the receiver tank. A second load cell readout device is coupled to the second weighing system for providing an output indicative of the weight of the receiver tank. A helium supply is provided and a pressure load panel is coupled between the helium supply and the propellant loading tank for providing pressure to transfer the propellant to the propellant storage tank in the spacecraft.
