为了提高新一代GPS标准体系中测量不确定度的评定精度,将数据融合算法引用到测量不确定度评定中。在最小二乘法基础上,根据线性加权融合原理,求得融合结果。实例验证,该方法简单易行,在同等实验条件下提高了精度,符合新一代GPS标准的要求。
In order to improve the accuracy of measurement uncertainty evaluation in the standard system of the new generation GPS, data fusion algorithm will be applied. According to data fusion principle, based on the least- squares method, the results of fusion are obtained. Experiment results show that the method is simple and improves accuracy under the same experimental conditions. It thus meets the requirements of the new generation of GPS standards.
