Inter-Satellite Link Enhanced Orbit Determination for BeiDou-3

Journal of navigation, 2019
The third generation of the BeiDou navigation satellite system (BDS-3) is a global navigation system, and is expected to be in full operation by 2020. High-precision orbits are a precondition for BDS-3 to provide a highly accurate service, which needs a ...
