A secondary universal communication system enables dedicated and independent communications capability between space vehicle payload elements and ground based communications networks. The system may either utilize existing communications satellites as an intermediate network to provide continuous communications with payload elements, regardless of orientation or configuration of the space vehicle, or may communicate directly with ground stations via down link capability. The system has a navigation system and an inertial measurement system to provide antenna pointing and tracking capability to actively track satellites. The secondary universal communications system can provide supplemental and independent communications capacity to the space vehicle's primary communication system.

[ What is claimed is:] [1.]1. A secondary universal communication system for a payload element located with a space vehicle which operates independently of a main communication system on the space vehicle, the secondary universal communication system comprising:an antenna unit;a transmitter/receiver unit, that is coupled to the antenna unit and to the payload element, for providing direct communication of data between the payload element and at least one of a ground station, another space vehicle, and an orbiting space station via the antenna unit without utilizing the main communication system of the space vehicle.
