摘　　要：介绍了一种航空重力测量质量评估方法,即通过统计一个架次飞行的测线与全区所有切割线交叉点空间重力异常不符值均方差得到架次/测线精度指标,以实现对每架次测量质量进行量化评估的目的。利用该方法对3个GT-1/2A航空重力测区原始数据按架次进行了计算和统计,得出了架次/测线精度指标统计分布规律,为航空重力测量质量控制提供了新的方法和参考指标。A kind of quality evaluation method in airborne gravity survey is proposed in this paper.The accuracy of the flight and survey line is quantified by calculating the root mean square of discrepancies between measurements at intersection points of survey line and all tie lines.Using this method,data of three survey areas measured by GT-1/2 A gravimeter were analyzed,and the statistical distribution of the accuracy of flight and survey lines were obtained.This paper tries to provide a new method and evaluation indexes for quality control procedures in airborne gravity acquisition projects.
