Abstract: An optimum measurement subset with a specified number n of elements is generated from a set of N > n weighted input global navigation satellite system (GNSS) measurements. A group of trial measurement subsets is generated by removing a different individual weighted input GNSS measurement from the set. A value of accuracy criterion for a target parameter is calculated for each trial measurement subset, and the trial measurement subset with the minimum value of accuracy criterion is selected. A new group of trial measurement subsets is generated by removing a different individual weighted GNSS measurement from the previously selected trial measurement subset. A value of accuracy criterion is calculated for each new trial measurement subset, and a new trial measurement subset with the new minimum value of accuracy criterion is selected. The process is repeated until the selected trial measurement subset has the specified number n of elements.

Abstract translation: 从一组N> n个加权输入全球导航卫星系统（GNSS）测量中产生具有指定数目n个元素的最佳测量子集。 通过从组中移除不同的个体加权输入GNSS测量来生成一组试验测量子集。 为每个试验测量子集计算目标参数的精度准则值，并选择具有最小精度准则标准的试验测量子集。 通过从先前选择的试验测量子集中移除不同的加权GNSS测量来生成新的一组试验测量子集。 为每个新的试验测量子集计算精度准则的值，并且选择具有新的最小精度准则标准的新的试验测量子集。 重复该过程，直到所选择的试验测量子集具有指定数量的n个元素。
