在飞播造林的实践中,我们在“一次查表测量航标线”的方法的基础上,改进利用“三角余弦函数公式计算距离”的测量方法,效果很好,速度快,测量精度和工效都有所提高。现将测量原理、操作方法阐述如下:一、测量航标线的计算公式选好播区后,需对播区进行规划设计,测设航标点。航标点是摆设导航信号的位置,设在航播带的中央。由若干个航标点连成的线,即是航标线。航标线应垂直于基
In the practice of aerial seeding and afforestation, based on the method of “one look-up table to measure aids”, we improve the measurement method using “the cosine function formula to calculate the distance”, which has good effect, high speed, accuracy and ergonomics Increased. Now the measurement principle, the operation method is described as follows: First, the formula for measuring the beacon line After selecting the broadcast area, the need to carry out the planning and design of the broadcast area, measuring navigation mark. Navigation point is the location of the navigation signal, located in the center of the air show. A number of points from the voyage point, that is, aids. Aids to navigation should be perpendicular to the base
