介绍了机场净空区障碍物限高要求,探讨了GPS RTK加全站仪三角高程测量障碍物测量技术和方法,分析了测量精度,总结了此方法的特点。
The height limit of the obstacles in the airfield clearance zone is first introduced in this paper. Then, the obstacle measurement technology and method are dis- cussed combining GPS-RTK with triangle height measure- ment of total station. Finally, the measurement accuracy is analyzed and the characteristics of this proposed method are summarized.
