Servicing of spacecraft in the geostationary arc

The possibility of servicing geosynchronous spacecraft in connection with the development of the Space Station and its associated infrastructure is discussed. The proposed servicing infrastructure is presented as well as the design of a serviceable spacecraft, and a servicing scenario for a geostationary earth observation platform. The scenario employs the space based OTV, OMV, remote servicer and remote refueling system. It is shown that servicing geostationary spacecraft provides the largest economic benefit when performed on a scheduled basis.
