| 摘 要： | 就测站数量、观测时间和测站分布对估计钟差的影响进行了研究,结果表明:增加测站数量和观测时间,均有利于提高卫星钟差的估计精度;但随着测站个数的增加,计算耗时会随之增加,从而影响钟差的实时使用,因此,从兼顾钟差的精度和实时应用两方面考虑,只有选择适当的测站分布和测站个数,才有利于钟差的实时估计和应用.PPP定位中,基于估计... |

| Abstract: | The effects of the station amount,observation time and station distribution on the estimated satellite clock biases were analyzed.The results show that,general speaking,the increment of station amount and observation time is conducive to improve the estimated accuracy of satellite clock bias.However,the increment of station amount will increase the time-assuming,in order to ensure the accuracy and the property of real-time,it is useful to select the appropriate station distribution and amounts,which are con... |
