Description

technical field

[0001] The invention relates to a technical method for precise satellite timing. Background technique

[0002] The data processing methods of satellite timing are mainly divided into single station and multi-station. The common-view satellite timing technology based on multi-station mainly uses two GNSS receivers to observe the same satellite, eliminates the common error through the way of single difference between stations, and finally realizes the timing work, while the non-difference carrier phase observation value The single-station timing is to complete the final satellite timing by using the non-difference combination of observations and fine-tuning various error sources at the same time. The above two commonly used satellite timing methods are based on different data processing models, and the data processing is highly independent. It cannot realize the unified processing of various timing observation data, which not only increases the complexity of d...
