摘要
针对星间激光比对GPS相对定位精度结果的精确性和可信度问题,研究了星间激光比对GPS相对定位精度数据量的确定方法;运用数理统计方法推导了相对误差、置信水平和数据量之间的概率不等式;为实现激光比对结果的精确性、可信度和数据量选取的综合权衡提供了量化分析手段,仿真结果验证了该方法的正确性和有效性.
For the problem of the nicety and reliability of the result of comparison with GPS relative positioning accuracy using inter-satellite laser, this paper investigated on data volume determination method of comparison with GPS relative positioning accuracy using inter-satellite laser. Deduced the probability inequality of the relative error, the confidence level and the data volume by mathematical statistics method, which provides a quantitative analysis means for achieving the tradeoff between the nicety and reliability of the result of laser comparison and the determination of data volume. Simulation result shows the correctness and validity of the method.
