description	Improved orbit/covariance estimation and analysis (OCEAN) system and method are presented utilizing ground station observations collected from satelfiies 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. L'invention concerne un système et un procédé d'estimation et d'analyse de covariance orbitale (OCEAN) améliorés faisant appel à des observations de station terrestre collectées à partir de satellites en vol pour estimer les positions, les vitesses et autres paramètres de plusieurs satellites à l'aide d'algorithmes des moindres carrés pondérés (WLS) par lots et/ou d'estimation de lissage de filtre de Kalman (KFS) pour estimer chaque paramètre, avec ou sans une connaissance a priori des erreurs incluses avec chaque paramètre observé.
