| 摘 要： | 利用信躁比估算法对脉冲星数据库中适宜导航的脉冲星进行了脉冲到达时间测量误差计算。分析了测量误差随观测时间及探测器面积的变化情况。在此基础上,指出了在DOP值分析中脉冲星导航与GPS的不同点;按照脉冲到达时间TOA测量误差较小原则给出了10组脉冲星优选组合。分析了DOP值随观测时间及观测脉冲星数的变化情况。 |
| 关 键 词： | 脉冲星 脉冲到达时间（TOA） 导航定位 精度因子（DOP） |

| Abstract: | Pulsars' time of arrival measurement error were calculated using SNR method.The calculated pulsar which suitable for navigation was selected from pulsar database.The influence of observation time and detector area on measurement error were analyzed.Based on this,the differences of DOP analysis between GPS and pulsar navigation were given.The top ten group of pulsar were presented based on lower measurement error principle.The influence of observation time and detector area on DOP were also analyzed. |
| Keywords: | pulsar time of arrival navigation and positioning dilution of precision |
