| 摘 要： | 针对现行海空重力测量平台倾斜改正模型存在的近似性问题，提出了顾及地球扰动重力和科里奥利（Coriolis）加速度两个水平分量影响的平台倾斜改正修正模型，从理论上论证了使用修正模型的合理性，通过数值计算评估了使用近似模型可能带来的误差影响量值，同时使用实际观测数据验证了修正模型的有效性，为修改完善海空重力测量作业标准和数据处理模型提供了必要的理论支撑。

| Abstract: | A modified correction model, has takes into account of the effect of two horizontal acceleration components of Coriolis force and disturbing gravitational attraction, aiming at platform tilt in air-sea-borne gravimetry is proposed for the approximation of existing models. The reasonableness of using modified model is analyzed and demonstrated theoretically. The amount of influence due to the approximation of existing models is estimated by using numerical calculations. And a practical airborne gravimetry data set is used as a case study to test the efficiency of the proposed model. These works provide a reliable theoretical support to improve the existing models of data processing, uniform operation standards and for the next revision of existing rules for operations of airborne gravimetry. |
