摘要
为了评估航空重力系统的性能指标,通常采用对一条测试线多次往返飞行计算各条重复测试线内符合精度的方法。研究了一种较准确的计算各重复线对应点的方法,并在对应点处采用插值方法计算其重力值,利用测线上对应点的重力值进行均方差计算可以得到精度较高的内符合精度值。
In order to evaluate the performance index of airborne gravity system,the method for calculating the internal accord accuracy of repeated flight lines is usually used.We research a method for calculating precisely the corresponding point of adjacent survey lines where the gravity value is calculated by using interpolation.High precision internal accord accuracy could be achieved by using RMS calculation for gravity value of corresponding points on survey lines.
