Abstract : Some conclusions are that the integration of command and telemetry with tracking provides a fundamental and substantial benefit in equipment costs, both at the ground sites and in the vehicle. The integration does compromise the performance of communications and tracking to some extent; however, the benefits derived from the use of a single antenna, receiver and transmitter on the ground and in space to accomplish all of these tasks will represent a simplification and significant economies over the conventional tracking arrangement, which involves a multiplicity of equipments. If duplication of equipment is desirable on the basis of system reliability, it is more efficient to duplicate part or all of an integrated system than it is to duplicate part or all of a non-integrated system. The development of an efficient system, able to perform all these functions within a single band of communications frequencies and having a large information bandwidth, both at the satellite and at the ground stations, will permit efficient planning with resulting developmental and operational cost saving.
