摘要
探讨了GPSRTK差分数据的传输技术问题。通过分析RTK数据传输所采用UHF波特点、传输电文机理及影响传输距离的因素,研究了UHF波用于RTK通信的不足,并给出了扩频技术与软件无线电技术两种改进技术。
In this paper,the issue of transferring technique about GPS RTK is discussed.According to analyzing UHF of RTK data transferring,mechanism of transferring message and factor of affecting transferring-distance,the insufficiencies of RTK commubications with UHF are studied,and spread spectrum communication&software defined radio(SDR)technique are presented.
