摘要
提出了一种解算GPS基线向量的新方法。该方法不涉及“周跳的探测及修复”和“整周模糊度的确定”等问题。该方法的关键是基线向量的初始值的误差必须足够小(例如小于0.33周),利用线性组合观测值(-3φ1+4φ2)和(1φ-φ2)作为中间过渡,能满足这一要求。用实例验证了该方法的正确性和可行性。
A new method for solving GPS baseline vector has been put forward, in which the problems of “detection and repair of cycle slips” and “determination of ambiguity” can be avoided. The key point of this method is that the error of initial value of baseline vector must be very small, for example, less than 0.33 cycles. In this paper, the linear combination observations （-3φ1 ＋4φ2） and（φ1-φ2） are used as transition, thus this is fulfilled successfully. Many examples of testing and verifying the correctness and the feasibility of this method are presented.
