Orbital and Attitude Prediction Accuracy Requirements for Satellites

This paper examines the criteria for selecting the orbital and attitude prediction accuracy requirements for communications satellites. The accuracy requirements have been analyzed in terms of the various space operations involved, e.g., satellite acquisition, guidance and control, communications, telemetry, and command. It is hoped that the findings of this investigation will prove useful in satellite mission planning and design, thereby facilitating a judicious choice of the various satellite and ground components of the related subsystems.
