摘要
LGO内业处理软件包支持Leica所有仪器类型,以统一的方式管理TPS、GPS和水准数据,功能强大,易于使用,是适合用户自定义和智能向导的工具。然而LGO对GPS控制网的同步环、重复基线、异步环的搜索及闭合差计算、超限的检查没有提供很好的支持,达不到《全球定位系统(GPS)测量规范》(GBT 18314-2009)中的要求,导致用户需要手动处理。为此,基于边界结点的GPS控制网同步环和异步环搜索算法,笔者采用C#语言进行LGO的二次开发。研究表明,该方法在弥补LGO不足的同时,提高了控制测量精度和报告输出。
LGO package supports all type of Leica apparatus, such as unified management of TPS, GPS and Level. It is powerful, easy to use, and suitable for user-defined and intelligent guide tool. However, LGO did not provide a good support for checking GPS control network synchronization loops, repeat baselines, asynchronous loops, and overrun disclosures. It is not meet the requirements of ＂ global positioning system （GPS） measurements＂ （GBT 18314-2009） Therefore, based on boundary node of GPS control network the synchronous and asynchronous loop search algorithm are developed by using C # with LGO. Research shows that this method not only improves the inadequacy of LGO, but also improves the precisions of control points and offers the report output as well.
