一、从飞机上自动记录地形的用途有二1.检查航空地球物理测量的空地联系质量与偏航。原理是:将领航员标定在地形图上航线的地形,与仪器实际记录的地形进行对比。如空地联系质量好,对比误差应该是很小的。反之,则偏航较大。2.有助于异常的推断解释。为便于解释,航测仪(-25,-46)有4道检流计,可 First, the automatic recording of the terrain from the plane has two purposes 1. Check the quality and yaw of the open space associated with the measurement of aviation geophysics. The principle is: pilot will be calibrated on topographic map route terrain, with the instrument actually recorded terrain comparison. If the open space is of good quality, the comparison error should be small. On the contrary, the yaw is larger. 2. Help explain the abnormal inference. For ease of explanation, aerial survey instrument (-25, -46) has 4 galvanometer, can
