Abstract
An automated spacecraft orbit compensation system and method that maintains a spacecraft in a desired orbit. The spacecraft orbit compensation system and method is automated to minimize human intervention. The system includes apparatus for determining orbital errors (ranging data) and apparatus for determining the duration and orbital location of thruster firings to correct the orbit. Each of the apparatus are located at a ground station. The system and method generates ranging data indicative of the range of the spacecraft. The ranging data are processed to estimate the orbit of the spacecraft. The estimated orbit is used to compute a thruster burn plan for the following N days. The thruster burn plan is uploaded to the spacecraft. The above steps are repeated at regular intervals.
