Patent ID: 8899527

Claim:
A system mounted on a servicer spacecraft for transferring fluid to a client satellite, the client satellite including at least one storage tank having at least a first fluid transfer coupling, comprising: a) a fluid storage and routing system for storing and routing fluid from said servicing spacecraft to the at least one storage tank on the client satellite, said storage and routing system including at least one pressurized tank containing a pressurized gas, at least one fluid storage tank, and an associated fluid transfer coupling, first and second flow paths connecting said at least one fluid storage tank, said at least one pressurized gas tank and said associated fluid transfer coupling; and b) a flow control system configured for detecting and adjusting pressure and flow rate of said gas and fluid through said first and second flow paths, detecting pressure in the at least one storage tank on the client satellite once said associated fluid transfer coupling is coupled to the fluid transfer coupling on the client satellite, transferring fluid from said fluid tank, using pressurized gas from said pressurized gas tank, to said at least one storage tank on the client satellite via said first flow path at a pressure less than or equal to a pressure of the at least one pressurized gas tank, or via said second flow path at a pressure greater than a pressure of the at least one pressurized gas tank.
