| 摘 要： | 实时载波相位测量（ＲＴＫ）是全球定位系统（ＧＰＳ）应用中的最新技术，它可实时获得具有厘米级精度的点位坐标，具有速度快、精度高等优点．由于ＧＰＳ具有三维坐标信息，若将ＲＴＫ技术应用于道路定测可以集传统的中线放样和中平测量于一体，大大提高作业效率，具有良好的应用前景．为此探讨了ＲＴＫ在道路定测应用中的有关问题，包括适用于ＲＴＫ作业的道路中线任意点坐标的计算、坐标转换、高程计算等，提出了相应的数学模型及处理方法，为改进道路勘测手段、拓展ＲＴＫ技术的应用领域起到了促进作用．

| Abstract: | RTK(real time kinematics) surveying is a latest application of GPS. It can provide real time position at cmlevel accuracy with the advanlages of qUickness and preciseness. It is known that GPS can provide 3 - dimension infor- mation. So if RTK could be used to fulfil staking and leveling of road center line at same the, the working effectiveness would be highly raised. RTK has good prospects in road survey. In the paper, the relevant problems of usingRTK in location survey are discussed, including the'calculation Of coonlinate of albitlary point on road center line, co-'ordinate transformation, height calculation and so on. The model and processing method are given. The idea in thispaper can promote the application of RTK and improve road survey method. |
