A new ISL-aided method for improving real-time kinematic orbit and clock estimation robustness of LEO satellites with degraded onboard observations

Onboard global navigation satellite system (GNSS) receivers have become the most convenient means to realize autonomous orbit determination and clock estimation for low Earth orbit (LEO) satellites. However, signal outages and blockages in complex space environments cause GNSS observation degradation, which restricts t...
