    • Abstract
  • The constellation rotation error of autonomous orbit determination based on the inter-satellite measurement can be effectively eliminated using anchor stations.But,the accuracy of orbit determination using anchor stations is poor because of the system errors caused by ionospheric delay and tropospheric delay etc.An anchor station timing difference measurement method,using the principle that the system error of a navigation satellite to ground ranging link varies very little in a short time,is proposed to eliminate the system error of measurement system and improve the accuracy of autonomous orbit determination.Simulation results show that the rotation of the constellation can be effectively restricted using the anchor station method.Inaddition,the timing difference measuring algorithm performs better than direct measurement methods.
