| 摘 要： | 针对在短时间内GPS观测方程的法方程容易形成病态的实际,探讨用附加约束条件来消除其病态性的方法,然后用LAMBDA方法确定其整周模糊度。实际实验证明,对于单频GPS接收机,利用几个历元数据,使用该技术即可正确确定整周模糊度,从而实现cm级定位。

| Abstract: | Aiming at the ill condition easily occurred in the normal equation of GPS observation equations in short time observation,the correlated study is performed.The Method of Restricted Condition is used to eliminate the ill condition of the normal equation,and the LAMBDA method is used to fix the integer ambiguity.The corresponding experiments have been executed based on these techniques.The experiments results show that,for single frequency GPS receiver,the fixed ambiguity can be finished in several epochs and centimeter level of positioning accuracy is achieved. |
