摘要
外业数据采集与内业处理检核的时空阻隔问题一直是制约大地测量数据生产效率的瓶颈,提出建立基于GPRS网络的大地测量数据的传输处理系统,详细设计了系统各模块的功能以及数据的传输控制方法,可实现外业端数据的实时、可靠传输和内业自动检核处理,提高大地测量数据生产的效率。
As is well known, the problem of space-time delay which exists between field-work data acquisition and indoor-work data processing has been a bottle-neck in enhancing the efficiency of geodetic data producing for a long time. This paper suggests establishing a geodesy data transmission ＆ processing system based on GPRS （ general packet radio service） networks to resolve the bottle-neck mentioned above. It not only gives specific design of the functions and procedures of the modules that make up of the whole system, but also introduces the methods of data transmission control. In this way, the paper gives an approach of real-time ＆ safe field-work data transmission and automatic data check in the indoor-work data processing, which enhances the efficiency of geodetic data producing.
