航空重力测量中垂直加速度确定方法的比较

Comparison on the Determination of the Vertical Acceleration Using GPS for the Airborne Gravimetry

垂直加速度是航空重力测量的重要改正项之一。文中概述了利用GPS确定加速度的基本方法,从理论 上分析了GPS确定垂直加速度的精度,并利用航空重力测量实测数据,比较分析了惯常使用的3种垂直加速 度确定方法,得出了若干初步结论。

The vertical acceleration is one of the most important corrections in the airborne gravimetry The accuracy of the vertical acceleration using GPS is first estimated based on analytical models, then three different routine approaches with GPS are analyzed and compared using the real data from one airborne eravimetry test, and some initial conclusions are drawn
