本文介绍一种针对摆式积分陀螺加速度计(PIGA)的输出与回路状态变量进行实时测试的自动化测试系统。

In this paper an on-line automatic testing system is introduced which detects the output and loop state variables of a pendulous integrating gyro accelerometer (PIGA) by means of computers.

普通加速度计只能输出单向加速度信号，速度和位移量需要经过后续软件进行积分处理得到。

The conventional accelerometer can only measure the single direction acceleration. To get the velocity and the displacement value, subsequent integrating software is required.

对线加速度计辅助惯性姿态角测量的误差分析表明，测量误差由加速度计噪声、二次积分离散化、信标噪声和加速度计频率特性误差组成。

The error analysis shows that the measurement error is caused by the noise of the accelerometer, discrete double integration, noise of beacon and frequency characteristic error.
