摘　　要：由于不同部门的船载重力测量规范不统一,导致不同部门不同航次之间获取的船载重力测量数据可能存在比较明显的系统性偏差。提出了基于参考场进行多航次船载重力测量系统偏差调整方法,即以某参考场(如DTU10GRA数值模型)为背景,基于平差思想,将航次实测数据与参考场数据之间差异的统计平均值作为观测量,进行系统偏差计算、分析、检验及调整。实验结果表明,依据本文方法能够有效消除多航次船载重力测量数据基准的不协调性。As the Specification of ship-borne gravity measurement in different sectors is not unified,the shipborne gravity survey data of different sectors and different voyages sometimes exist obvious systematic bias. In this paper,the method of unifying measurement datum of multi-voyage ship-borne gravity measurement based on reference field is provided,and the basic ideal is that the statistical average difference between the ship-borne survey data and reference field data as observation is calculated based on the adjustment thought,using a reference field（ such as DTU10GRA） as background.The experimental results showthat this method is effective in unifying multi-voyage boat load gravity measurement datum.
