A space tug would capture a satellite, take it to a fuel depot, fuel it, and allow it to go on to its intended geosynchronous orbit.  The depots would be fueled with hydrogen and oxygen-- both excellent rocket fuels-- taken from water mined from asteroids.

Such a system would reduce the cost of space operations.
