【摘要】:利用天宫二号上的伽玛暴偏振探测仪(POLAR)观测数据完成了X射线脉冲星导航的原理验证.处理并分析了POLAR的观测数据,建立了基于轨道动力学模型和脉冲星脉冲轮廓显著性分析的定轨算法,并利用蟹状星云脉冲星的实测数据开展了单脉冲星的定轨分析.结果表明,该方法能够实现对天宫二号轨道的定轨,利用POLAR一个月的在轨观测数据可得到定轨精度如下(99.7%置信度):轨道半长轴精度7.0 m,偏心率精度0.00026,轨道倾角精度0.023°,升交点赤经精度0.17°,近地点幅角及平近地点角精度0.043°.
[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 掳, the elevation angle is 0.17 掳, and the perigee amplitude angle and the perigee angle are 0.043 掳.
