Up until now, satellites have not even been designed with refueling in mind, because, well, it wasn't possible. That will change if China can prove otherwise.

In geosynchronous orbit, a spacecraft completes one lap around Earth at the same rate as the planet's rotation, giving a satellite a constant view of the same geographic region.

Before communications satellites, such signals had to be relayed via earth-based relay towers which had to be placed in sight of one another. The original idea of geosynchronous communications ...
