Calibration of GRACE Accelerometer Using Reference Gravity Field Model Based on Energy Balance Approach
-
摘要: 利用多个参考重力场模型分别对GRACE一个月的实测加速度计观测数据进行检校。数值计算结果的比较分析表明了利用参考重力场模型确定加速度计校准参数是有效的。Abstract: The principle and method of the determination of calibration parameters(scale,bias and drifting) of GRACE accelerometer using reference gravity field model based on the energy balance approach are discussed in detail.One month GRACE acceleration data are calibrated using the different reference gravity field model.The analysis and comparison of the numerical results show the validation of calibration of accelerometer using the reference gravity field model.
