Abstract:

The basic principles of X-ray pulsar-based navigation and X-ray pulsar sequential observation are introduced. An observation value processing method is proposed based on measured satellite data. Based on the original observation data received by the high energy X-ray detector in China's first large-scale astronomical satellite "Insight-HXMT", the processing accuracy results of the navigation observation value are given. At the same time, the precise orbit determination ephemeris is used as the standard orbit, and is compared with the X-ray pulsar navigation results. It is concluded that the accuracy of X-ray pulsar-based navigation of the Insight-HXMT satellite data is about 10 km. Finally, according to the navigation results of the measured data, the insufficient aspects of this experiment are discussed and future suggestions are given.
