| 摘 要： | 航空重力测量中测线的长度的往往要长于测量区域,测线长出测量区域的长度就是留给航空重力仪必要的稳定距离。以2011年某地区的实际测量数据为例介绍了稳定距离对航空重力测量的精度的影响,数据处理结果表明,在平稳的气象条件下稳定距离不够则其交叉点重力异常不符值抗差后可以达到±12.0648mGal,交叉点重力异常不符值均值可以达到±16.9091mGal。

| Abstract: | The lines in the airborne gravimetry are always longer than the length of the measurement area.The addition distance is for the airborne gravimetry instrument to be stabilized.This paper uses an actual measurement data to state the influence of the line stable distance to the accuracy of airborne gravimetry,and the results of processing data show that on the smooth meteorological conditions shorter stable distance made the robust estimation of the gravity anomaly get to± 12.0648mGal,and the mean gravity anomaly discrepancy of the line crossings is±16.9091mGal. |
