摘要
由RTK测量中数传电台的不足入手,从理论上技术上分析了在RTK中引入GPRS的必要性和可行性,并且根据RTK的特点设计了GPRS在RTK中的工作模式,进而介绍了一种手持式GPRS数传设备的软硬件设计和工作流程。最后经过测试,证明了GPRS作为数据链,完全满足RTK作业的要求。
Because the broadcasting station has shortages in the RTK, a kind of new data link should be introduced. This paper analyses the necessity and feasibility to introduce GPRS into RTK. Based on a kind of suitable GPRS work mode designed for RTK, a kind of GPRS handset for data transmitting has been developed. The hardware and software of the handset are also introduced in this paper. The testing proves that the GPRS data link can be used in the RTK.
