Design and research of a high-precision positioning system based on ground-based networking
Time-Loop technology uses one base station as the main time standard,and other base stations are synchronized with the main base station,using nanosecond signals for time synchronization.The principle is that the time signal receiver installed inside the auxiliary base station receives the time signals from both the autonomous base station and the home base station,thus forming a time signal feedback loop to gradually synchronize with the home base station.Then measure and adjust the signal of the autonomous base station,wait for the auxiliary base station and the main base station completely synchronized,the auxiliary base station sends a"healthy"signal can be integrated into the constellation system of the positioning base station.
