Autonomous orbit determination for satelite formations using relative sensing: observability analysis and optimization

  title={Autonomous orbit determination for satelite formations using relative sensing: observability analysis and optimization},
  author={Pedro Rocha Cachim and Joao Gomes and Rodrigo M. M. Ventura},
Orbit determination of spacecraft in orbit has been mostly dependent on either GNSS satellite signals or ground station telemetry. Both methods present their limitations, however: GNSS signals can only be used effectively in earth orbit, and ground-based orbit determination presents an inherent latency that increases with the Earth-spacecraft distance. For spacecraft flying formations, an alternative method of orbit determination, independent of external signals, consists in the observation of… Expand
