摘    要:动态重力测量技术是惯性技术的一种典型应用。作为动态重力测量系统不可或缺的一部分,稳定平台的功能是提供一种能够隔离载体动态、实时跟踪参考系的物理装置,或提供载体相对于参考系姿态信息的软件算法。当前大多数的稳定平台,都是基于惯性元件构建的,可称之为惯性平台。从稳定平台的角度对几种常见重力仪进行分类,对采用四种类型惯性平台的重力仪进行较详细的分析和评述,即双轴阻尼陀螺稳定平台、捷联方位双轴惯导平台、三轴惯导平台和捷联惯导平台。

关 键 词:重力测量  惯性技术  重力仪  惯性导航系统  陀螺  加速度计  姿态  平台  捷联

Abstract:Dynamic gravimetry is a typical application of the inertial technology. The stabilized platform, an indispensable component of a dynamic gravimeter, provides a physical device to isolate the dynamics of the craft and to track a reference frame, or provides the software flame for the craft. The stabilized platforms of modem algorithm of the attitude information with respect to this dynamic gravimeters, though in different forms, are all constructed based on inertial sensors, i. e. , gyroscopes and accelerometers, and as a result, can be termed inertial platforms. The widely used dynamic gravimeters are classified in terms of different stabilized platforms. These gravimeters, with four different platforms of the two-axis damped gyro-stabilized platform, the strapdown- azimuth two-axis inertial navigation platform, the three-axis inertial navigation platform, and the strapdown inertial navigation platform, are analyzed and summarized in a relatively comprehensive manner.
Keywords:gravimetry  inertial technique  gravimeter  inertial navigation system  gyroscope  accelerometer  attitude  platform  strapdown
