|Abstract:||Autonomous time synchronization is one of key technologies to realize autonomous navigation for Global Navigation Satellite System (GNSS), whose accuracy directly affects the system positioning, navigation and timing. Based on the bidirectional time synchronization principle, the inter-satellite pseudo-range equation is obtained after analyzing the impact of time delay by different types of error. The satellite clock model is established by certain part and random part. Finally, the Kalman filter and the adjustment algorithm are studied for inter-satellite autonomous time synchronization, which are combined by weighted parameters to design a weighted synthesized algorithm.|
