运用UEDIT及Excel开发GPS基线检核工作表程序

Application of UEDIT GPS and Excel in Developing GPS Baseline Check Worksheet Program

GPS观测成果的基线检核是确保外业观测质量,达到预期平差精度要求的重要环节。因此在观测任务结束后,必须及时对外业观测数据质量进行检核和评价,以发现不合格的数据,并根据情况采取删除、重测或补测等措施,但目前很多GPS基线解算软件并不能提供满足实际工程需要的基线解算检核步骤的成果,给GPS基线解算检核带来困难。就如何利用UEDIT专业文本编辑器及Microsoft Excel工作表交互使用、编制GPS基线解算检核程序进行了阐述,以期能提高实际工程中GPS数据处理的能力。

Baseline check of GPS observation results is an important part to ensure outside observation quality and adjustment accuracy. Therefore, check and evaluation must be done on the quality of observation data after the observation, so that failed results can be detected in time and measures as deleting and re -testing can be taken accordingly. The present GPS baseline solution software, however, cannot provide baseline solution check steps meeting the needs of actual project, causing difficulties to GPS baseline check. The paper expounded ways to use UEDIT professional text editor and Microsoft Excel worksheet to prepare baseline solution checking procedures, aiming at improving GPS data processing ca- pacity in actual project.
