[Abstract]:The principle of X-ray pulsar navigation is verified by using the (POLAR) observation data of gamma burst polarization detector on Tiangong 2. The observation data of POLAR are processed and analyzed, and the orbit determination algorithm based on orbital dynamics model and pulsar pulse profile significance analysis is established, and the orbit determination analysis of single pulsar is carried out by using the measured data of crab nebulae pulsar. The results show that the orbit determination accuracy of Tiangong No. 2 orbit can be realized by using the in-orbit observation data of POLAR for one month, and the orbit determination accuracy is as follows: the orbit semi-long axis accuracy is 7.0m, the eccentricity accuracy is 0.00026, the orbit inclination accuracy is 0.023 擄, the elevation angle is 0.17 擄, and the perigee amplitude angle and the perigee angle are 0.043 擄.
