The Distributed Processing Algorithm for Autonomously Updating the Ephemeris of Navigation Satellite by Inter-Satellite Links

    Graphical Abstract
    • Abstract
  • In order to continue to issue the broadcast ephemeris after losing the ground link for some time,the GNSS of our country designs to provide the payload of crosslink ranging and communication.The precision orbit determination and integrity with regional station deploying can also be improved by this crosslink.The paper presents a distributed Kalman filter algorithm of precision orbit determination for inter-satellite range measurement,and the validity of this method is verified by simulating test.It's showed that,Supporting by the sufficient number of inter-satellite links,a better than 3 meter URE precision of satellite orbit can be meet during 60 day.
