摘要
为了削弱各类误差源的影响,提出了一种两阶段误差综合补偿方法:第一阶段采用相关分析法对仪器厂家标定的交叉耦合改正(CC改正)的不足进行修正;第二阶段采用测线网平差对各类剩余误差的综合影响进行补偿。实际观测数据处理结果验证了该方法的有效性和可靠性。
In order to eliminate the disturbance of different kind of errors, we propose an integrated method with two steps for compensating the systematic errors of marine and airborne measurements from L&R gravimeter. Firstly, crosscorrelation analysis is used to make corrections for the original cross-coupling correction coefficients obtained from the instrument manufacture, and give a systematic correction to the observed gravity. Then surveying line system adjustment is applied to the corrected gravity to further eliminate the disturbance of remainder errors. A practical marine gravity measurement set is used to prove the efficiency of the integrated data processing method.
