摘要 LaCoste&Romberg航空重力仪是我国航空重力测量系统的核心。根据航空重力测量的特点，讨论了航空重力仪格值的标定方法，导出了格值计算公式。基于实际标定数据，计算获得了新格值。利用大同航空重力测量实测数据对新格值的有效性进行了验证。结果表明，利用新格值可以使空中重力扰动与参考值之间的系统误差减小约1×10 -5 ms -2。
Abstract：LaCoste&Romberg airborne gravimeter is the key equipment of the Chinese airborne gravimetry system. On the basis of the characters of the airborne gravimetry, the calibration method of the meter factor for the airborne gravimeter is discussed and the formula for computing the meter factor was derived. Thus,a new meter factor is determined using actual calibration data. The validation of the new meter factor is verified using the real airborne data from the Datong test. The results indicate that the systemic biases of the airborne gravity disturbance compared to ground reference can be reduced about 1×10 -5 ms -2 by use of the new meter factor.
