Abstract

System and methods provide tracking capabilities by one or a plurality of satellites for a mobile terrestrial terminal. A user requests that a satellite track a particular mobile terrestrial terminal. If the user privilege level allows for this level of control, the satellite adjusts to track the identified terminal. One method for tracking involves the use of a steerable antenna in which the antenna steers to maintain a footprint over the identified mobile terminal. Another method for tracking involves moving the satellite itself to maintain a footprint over the identified mobile terminal. The tracking functionality may utilize a closed loop tracking method.
