摘　　要：针对广电工程因发射天线电磁环境影响以及天线屏蔽、遮挡等原因造成的全球导航卫星系统(GNSS)观测数据质量较差的问题,本文通过对GNSS数据预处理软件(TEQC)进行可视化界面开发,在Windows环境下实现广电工程GNSS观测数据质量检核、报表输出和预处理等功能。通过对某中央发射台站广电工程GNSS测量数据处理的实例验证,结果表明,TEQC可视化软件可以准确评估、检核广电工程GNSS观测数据质量,经预处理后能够获取较高质量的观测数据,有效提高广电工程GNSS控制测量观测数据质量。In view of the poor quality of global navigation satellite system(GNSS)observation data in radio and television engineering due to the electromagnetic environment of transmitting antenna,shielding and other reasons,through the visual development of translation,editing and quality checking(TEQC)software,the functions of GNSS observation data quality inspection,report output and preprocessing of radio and television engineering can be easily realized in Windows environment.Through the experimental verification of GNSS control network data of a central transmitting station radio and television project,the results showed that TEQC visualization software could accurately evaluate the quality of GNSS observation data,and obtain high-quality observation data after preprocessing,which played an important role in improving the quality of GNSS control network observation data of radio and television project.
