摘要
动态重力仪和惯性导航系统的核心元件都是惯性元件,即陀螺仪和加速度计(重力传感器可以认为是一种特殊的加速度计),因此重力测量与惯性导航具有紧密的联系。从比力测量、物理与数学平台、惯性手段辅助重力测量,以及重力辅助惯性导航等方面分析了重力仪与惯性导航系统的紧密联系。并对惯性导航与重力测量的融合应用进行了分析。
Both dynamic gravimeters and inertial navigation systems have inertial sensors as their core components,i.e.gyroscopes and accelerometers,and the latter includes gravimetric sensors.So there are close connections between gravimetry and inertial navigation.The connections between gravimeters and inertial navigation system are analyzed in the perspectives of specific force measurement,physical and mathematical platform,inertial technology aided gravimetry,gravity aided inertial navigation,and so on.The fused application of gravimetry and inertial navigation is also analyzed.
