Geostationary Satellite Station Keeping Robustness to Loss of Ground Control

For the vast majority of geostationary satellites currently in orbit, station keeping activities including orbit determination and maneuver planning execution are ground-directed dependent on availability ground-based satellite control personnel facilities. However, a requirement linked to autonomy survivability cases interrupted ground support is often one stipulated provisions platform design. It especially important for military-purposed remain within its designated orbital window, order provide reliable uninterrupted telecommunications services, absence resources due warfare or other disasters. In this paper we investigate factors affecting robustness satellite’s terms maximum duration window can be maintained without intervention. By comparing simulations evolution, given different initial conditions operations strategies, variation parameters study has been performed have analyzed which most sensitive to. This also provides valuable insights into may worth controlling by military civilian operator. Our show that beneficial factor maximizing time will operational practice pre-emptively loading East-West maneuvers automatic board should capability lost. The second using short cycle durations.
