摘要
简要介绍了当前常用重力仪类型和标称精度,并就运输工具性能好坏、重力测段大小、路线距离长短和观测时间长短对相对重力仪的观测精度的影响进行测定分析,结果表明:影响重力仪观测精度的主要因素与汽车运输工具有关,选择越野性能好,减震效果好的汽车作为完成高等级流动重力测量任务的前提条件。
A brief introduction of the current commonly used gravity type and nominal accuracy, and the transport per- formance, gravity segment size, route distance length and the observation time on relative gravity observation accuracy were determined and analyzed, the results show that : the effect of gravity observation precision and the main factors of automobile transportation tools, choose good off-road performance, good shock absorption effect of the car as complete high grade mobile gravity measurement task prerequisite.
