Galileo, Compass and QZSS: Current status of the new satellite navigation systems

摘要

The current status and future developments of the new satellite navigation systems Galileo, Compass, and QZSS are presented and requirements for receivers and antennas are discussed. Global multi-GNSS tracking data allows for orbit and clock determination of these systems. A combined analysis with GPS is currently mandatory due to the limited number of satellites. The estimated satellite orbits have a decimeter accuracy level. The current deployment status of Compass allows for precise point positioning with Compass observations only. These Compass-only results agree with the GPS-only results in the order of several centimeters.
