测绘（gps）英语翻译

RTK技术的出现使施工放样有了突破性的发展，不但克服了传统放样法和坐标放样法的缺点，而且具有观测时间短，精度高、无须通视、现场给出精确坐标等优点。经现场检测，在距离参考站约3公里处，平面定位误差小于5cm，高程误差小于10cm。GPS接收机只要1~3min就能进入RTK工作状态，在此状态下1min内即可得到厘米级的点位精度。RTK技术特别适合道路等大批量设计点位的放样工作，尤其是道路边桩，征地范围线,工程测量等放样。无须沿途布设图根控制点，从而减少施工控制网的布设密度，节约经费，节省时间。由于其无须通视等优点和可以单人作业更显示出其优越性。

The RTK technology's appearance enabled the construction lofting to have the unprecedented development, not only has overcome the traditional lofting law and the coordinate lofting method shortcoming, moreover had the hour of observation to be short, the precision high, did not need the intervisibility, the scene to give merits and so on precise coordinates. After the scene examination, in stands the approximately 3 kilometers from the reference place, the plane position error is smaller than 5cm, the vertical error is smaller than 10cm. So long as the GPS receiver 1~3min can enter the RTK active status, in 1min then obtains the centimeter level spot position precision under this condition. Mass des
