| Abstract: | The equipment and operation of Augamentation System Reference Station is discussed. The advantage and disadvantage for timing information from receiver is analysed. An scheme is designed for the data fusion which come from GPS receiver and Rb atomic clock data. By the experiment, it shows that the scheme is effective, and can improve the index performance, such as the stability performance, which reaches 0.1μs per day and 1 ms per year. |
