| 摘 要： | 为使GPS接收机在卫星星座不完整情况下仍能定位,提出采用接收机时钟偏差模型辅助接收机定位的方法.将模型预测的时钟偏差引入伪距线性化定位解算方程中,保证了在GPS星座不完整时仍能给出接收机的位置.基于GPS实测数据的验证分析表明,该方法的定位精度在标准误差范围内.同时,该方法具有计算简单、有效可行的特点,可以方便地嵌入到GPS接收机中.

| Abstract: | An auxiliary method for GPS receiver positioning using clock bias forecast model was developed when GPS constellation was incomplete.The estimated clock bias was introduced into the pseudorange equations,which ensured the GPS receiver could estimate its position even in incomplete constellation.The validation and analysis based on the real GPS data show that the positioning error of the proposed method is in the standard deviation range.Meanwhile,the method is much more convenient,effective and feasible whe... |
