| 摘 要： | 由于高动态目标对定位实时性要求高 ,GPS伪距测量方程的求解采用直接解算法。不同于一般的直接解算法 ,导航方程中考虑测量噪声的存在。文中导出了直接解算定位信息的公式 ,并对算法在空间定位中解算结果的存在性、唯一性和稳定性进行了讨论。

| Abstract: | GPS Pseudorange measurements are applied in dynamic positioning.This paper takes account of the additive noises involved in the pseudorange measurements.Because the dynamic target demands real time positioning,the direct solutions are used to the navigation equations,the formulas have been derived.The existence,uniqueness and stability of GPS solutions are discussed for the algorithm application in space positioning. |
