摘要
本文以高精度重力测量资料处理的数学模式为基础,叙述了用于LCR重力仪标定和重力网平差的软件包ACGN系统的主要功能和特点;对重力仪精密标定和重力网最优平差等问题进行了讨论。 实例计算表明:高精度重力测量资料的处理,不仅与所选数学模式有关,而且与具体计算穷案有关;ACGN系统正是一个高精度、高效率处理精密标定重力仪、平差各类重力网观测结果的通用软件包。
Ba sed on the mathematical mode processing high precision gravimetry data, we discussed in this paper primary function and characteristics of ACGN software package system which can be used for the calibration of LaCoste-Romberg gravimeters (LCR)and the adjustment of gravimetic network. Some problem relevant to precision calibration of the gravimeter and optimum adjustment of the gravimetric network are discussed too.Calulation shows that processing of high precision gravimetry data has something to do with non only selected mathematical mode, but also the specific project used in the calculation. Calculation also shows that ACGN system is a multi-usage sofftware package with high precision and efficiency, This system can be used to observing data of the precison calibration gravimeter and adjustment gravimetric networks of various kinds.By observed the gravimetric data 9 LCR gravimeters, we have respectively accuraies of the adjustment gravity difference better than ±3.5 μgal for the gravimeter calibration line in the Lusan mountain and ±1.3 μgal for the vertical gravimeter calibration line in Wuhan.
