我国现行的GPS测量规范采用的是环三维坐标分量闭合差、同步环和异步环闭合差作为衡量指标；而大多数商用GPS软件采用的是环水平和垂直分量闭合差作为质量评定的标准，且无同步环、异步环统计功能。为了将商用软件基线解算结果转换成我国规范相对应的同、异步环统计结果，进行了相关程序设计。通过算例分析表明，用三维坐标分量闭合差更有利于GPS外业的质量控制，且能分别统计出同步环和异步环，较商用软件更有利于外业质量检验。
我國現行的GPS測量規範採用的是環三維坐標分量閉閤差、同步環和異步環閉閤差作為衡量指標；而大多數商用GPS軟件採用的是環水平和垂直分量閉閤差作為質量評定的標準，且無同步環、異步環統計功能。為瞭將商用軟件基線解算結果轉換成我國規範相對應的同、異步環統計結果，進行瞭相關程序設計。通過算例分析錶明，用三維坐標分量閉閤差更有利于GPS外業的質量控製，且能分彆統計齣同步環和異步環，較商用軟件更有利于外業質量檢驗。

At present,China′s specification uses a three-dimensional coordinate components misclosure ring,synchronous and asynchronous loop closure ring as a measure;while most commercial GPS soft-ware use closed loop horizontal and vertical components as quality assessment standards,and no syn-chronous ring,asynchronous ring statistics.The related program was designed to convert the commer-cial software baseline results into the simultaneous and non-simultaneous loop statistical results corre-sponding to China's specification.The results show a three-dimensional coordinate components misclo-sure more conducive to quality control GPS,and can sync statistics and asynchronous ring,respective-ly.3 D coordinates component closure is more conducive to the quality inspection compared with the commercial GPS software.
