摘要 La Coste&Romberg型海空重力仪,它是我国两套航空重力测量系统CHAGS中的一个核心。本文讨论了对该类型重力仪的短基线格值标定方法,给出了不同条件下的格值标定的数据处理公式,分析比较了不同格值对航空重力测量精度的影响。结果表明,潮汐改正及仪器掉格对短基线格值标定结果影响较小。 La Coste Romberg Air Sea gravimeter is the key equipment of the CHAGS of our two airborne gravimetric system. The short baseline calibration of scale value method is discussed,the expressions between different qualification are provided,and the influence of different scale value to airborne gravimetric precision is compared. The result indicates that the influence of tide and drift is tiny for short baseline calibration of the meter factor.
