| Abstract: | Based on space-based data of RXTE satellite, we established the method of a space-time coordinate system conversion, time correction and epoch folding, constructed the Crab pulsar contour for extracting navigation information, analyzed the structure and characteristics of space-based loads, and simulated the background radiation with RXTE satellite. In the setting condition of navigation, the accuracies of a single satellite orbit and multi-satellite orbit positionings were quantitatively analyzed, and the urgent attention to the technical problems to improve the navigation and positioning accuracy was described in the later pulsar navigation detection. |
