A space module has an outer structure designed for traveling in space, a docking mechanism for facilitating a docking operation therewith in space, a first storage system storing a first propellant that burns as a result of a chemical reaction therein, a second storage system storing a second propel
A space module has an outer structure designed for traveling in space, a docking mechanism for facilitating a docking operation therewith in space, a first storage system storing a first propellant that burns as a result of a chemical reaction therein, a second storage system storing a second propellant that burns as a result of electrical energy being added thereto, and a bi-directional transfer interface coupled to each of the first and second storage systems to transfer the first and second propellants into and out thereof. The space module can be part of a propellant supply architecture that includes at least two of the space modules placed in an orbit in space.

The system of claim 11 wherein the binary code sequence is a Barker code comprising approximately the same number of positive and negative bits.15. The system of claim 14 wherein N is seven or eleven.16. A method of detecting a sequence of bits having a known pattern, the method comprising; sampling each bit of an input bit sequence at least twice to produce at least two versions of the input bit sequence; comparing each bit of each produced version of the input bit sequence to a corresponding bit of a reference bit sequence; and generating a detection signal in response to the comparing including increasing a value of the detection signal for each matching pair of compared bits and decreasing the value of the detection signal for each non-matching pair of compared bits, the detection signal indicating detection of the sequence of bits when the value of the detection signal exceeds a predefine value. 17. The method of claim 16 wherein the sampling is performed by a shift register having a clock input.18. The method of claim 17 wherein the comparing is performed by a code matching filter having a clock input.19. The method of claim 18 wherein the clock input to the shift register and the clock input to the code matching filter are the same.20. The method of claim 16 wherein sampling includes sequentially sampling each bit of the input bit sequence at least twice. ugh molecular sieves.4.
