摘要
针对短基线动态相对定位中快速解算整周模糊度的难题，提出了一种新的方法——GPS单历元解算整周模糊度。文中对相关的观测方程、载波相位的观测精度、真假解的识别等问题进行了详细讨论。试验证明，该方法正确、可靠，解决了快速解算整周模糊度这个难题，克服了传统方法需要进行静态初始化等问题。将该方法应用在车辆、舰船等移动载体上，可以实现真正意义上的实时动态相对定位，具有重要的应用价值。
Fast resolution of integral cycle ambiguity has been a challenge in short baseline dynamic relative positioning. This paper proposes a new method called Resolution of Integral Cycle Ambiguity with GPS Single Epoch. Detailed discussions are given on issues including associated observation equations, observation accuracy of carrier phase and identification of true and false solutions. Experiments show that the method is correct and reliable. Compared to tradition methods, it has eliminated the requirement of static initialization. Realtime dynamic relative positioning can be achieved in the real sense if the method is applied on mobile carriers such as vehicles and vessels. Therefore, it is of significant values for application.
