| 摘 要： | 提出了一种基于验后估计法定权的组合GPS/GLONASS单点定位方法。研究表明 ,该方法理论上严格 ,实践上可行 ,比根据经验给GPS/GLONASS组合观测量值定权更合理。该方法可以推广到组合GPS/GLONASS伪距和载波相位相对定位。

| Abstract: | It is well known that the precision of GPS observations is different from that of GLONASS. Therefore, the correct determination of the weights of observations is vital for a combined GPS/GLONASS positioning. In this paper, the method of weighted GPS+GLONASS single point positioning based on posteriori estimation was proposed, which is more reasonable than weighting on the basis of experience. The method can be extended to apply in relative positioning using pseudo range or carrier phase observations. |
