摘要
目前常规RTK技术在测区情况复杂的条件下时常遇到作业距离短、流动站失锁频繁、架设基准站次数多的问题,造成作业效率低下,不能充分发挥RTK技术的特色。基于网络基站的RTK技术是GPS-RTK技术的进一步延伸,其通过互联网接入的通讯方式向流动站传送参考站数据,采用网络通讯大大延伸了RTK的作业半径,扩展其作业范围,并将定位精度和可靠性进一步提高。以十漫高速公路土地登记测量项目为例,通过作业流程和数据精度分析表明,网路基站技术比常规RTK技术更加优越,从而为类似工程线性测量工作开辟了新的途径。
Currently,under complicated conditions,conventional RTK technology in the surveyed area often encounters the problems such as operating within a short distance,mobile stations frequently losing its lock,base station setting up too many times,which lead to operating inefficiency,thus it can not give full play to RTK technology features.Network base station technology is the further extension of GPS-RTK technology,which transmits the reference station data to the mobile station by means of the communication through Internet access.Network communications are used to greatly extend the operational radius of the RTK,expand the scope of its operations,and further improve the positioning accuracy and reliability.By taking the example of Shiman Freeway measurements,this paper proves the superiority of network base station technology from the project process to the accuracy of data analysis,and opens up new avenues for linear measurements of projects.
