fullstationkeeping

Full stationkeeping refers to the process of maintaining a spacecraft's position and orientation within a designated operational area in space. This involves a combination of thruster firings and attitude control maneuvers to counteract external forces such as atmospheric drag, gravitational perturbations, solar radiation pressure, and orbital decay. Unlike partial stationkeeping, which might only focus on maintaining altitude or orbital path, full stationkeeping addresses all aspects of the spacecraft's trajectory and orientation.

The primary goal of full stationkeeping is to ensure the spacecraft remains in its intended operational orbit or position for the duration of its mission. This is crucial for a variety of applications, including Earth observation satellites that need to image specific regions consistently, communication satellites requiring a stable link with ground stations, and space telescopes that demand precise pointing accuracy. Autonomous systems are often employed to manage stationkeeping, using onboard sensors like star trackers and GPS receivers to monitor the spacecraft's state and control systems to execute the necessary corrections. Regular maneuvers, though small, are performed to prevent significant deviations.
