This paper presents a study of the orbit determination of low-Earth orbit (LEO) spacecraft using GPS observable. The statistical approach based on least squares estimation associated with differential correction has been implemented to estimate the position and velocity of the spacecraft. The spacecraft dynamics and orbit perturbation from Earth oblateness, particularly effect, were taken into account. The estimates were evaluated by the conventional orbit propagator.
