航空重力测量测线网平差中的粗差处理

摘要

The main task of network adjustment of airborne gravimetry is to compensate systemic errors. In order to weaken the influence of outliers and improve the effect of compensation, this paper brings in thresholding and robust estimation, and confirms these two methods' validity and reliability in simulated data processing. By means of comparison, a conclusion is reached that the robust estimation has more practical value in the network adjustment of airborne gravimetry.%航空重力测量测线网平差的主要任务是进行系统误差的补偿.为了削弱粗差观测值的影响,提高补偿效果,引入阈值法和抗差估计,并采用模拟数据验证了这两种方法的有效性和可靠性.通过比较发现,抗差估计在航空重力测线网平差中具有更好的实用价值.
