Abstract:

Improved orbit/covariance estimation and analysis (OCEAN) system and method are presented utilizing ground station observations collected from satellites passing overhead to estimate the positions, velocities, and other parameters of multiple satellites using weighted least squares (WLS) batch and/or Kalman filter smoothing (KFS) estimation algorithms to estimate each parameter, with or without a priori knowledge of the errors involved with each observed parameter.
