Abstract The paper discusses the existence and unobservability of the constellation rotation error of autonomous orbit determination of navigation satellites with crosslink ranging observation as well as the rank defect problem; then analyzes the influence of tide perturbation on the constellation rotation error and autonomous orbit determination. The processing results of simulation data indicate that tide perturbation has a great impact on the error of alongtrack and cross of autonomous orbit determination(the relative error is about 4 m in the 110th day) and the impact will become bigger with the increase of days of the autonomous orbit determination. Therefore, the influence of tide perturbation must be considered in the highprecise and longtime autonomous orbit determination.
