摘　　要：利用北斗卫星导航系统的短报文通信功能,改变传统定位差分信息的播发方式,建立一种新型定位模式。通过拉距收敛试验,分析接收机静态和动态的定位精度,并验证新定位模式的可靠性。试验结果表明:该方法能够满足远海施工高精度定位要求。A new positioning mode with the short-message communication function of the Beidou satellite navigation system is set up, which changes the traditional broadcasting way of differential positioning information. The static and dynamic positioning accuracy of the receiver is analyzed by the drawing measure and error convergence test, with which the reliability and stability of the new positioning mode are tested and verified. It is shown that the method can meet high precision positioning requirement of the pelagic construction project.
