| 摘 要： | 提出了测线系数修正法,即在交叉点处采用平差的思想对每条测线的交叉耦合(CC)改正监视项的系数进行修正,然后采用新系数重新计算CC改正。实验结果表明,采用修正后的系数能补偿外界的动态测量条件与仪器生产厂家计算CC改正系数时设计的假设条件之间的差异对CC改正造成的影响,提高海洋重力数据处理的精度。

| Abstract: | Based on the linear relation between the cross-coupling correction and 5 cross-coupling monitors,the method for modifying the coefficient of every surveying line were obtained.The method is divided into two steps.Firstly,based on the adjustment principle the coefficients of 5 cross-coupling monitors of every surveying line are modified at junction points.Secondly,cross-coupling correction is calculated using the new coefficients.Experimental results show that the new coefficients can compensate the influenc... |
