惯性导航设备升沉数据测试系统研究

研制了一套基于STM32单片机与单轴摇摆台的测试系统,利用固定圆心、固定半径条件下的圆内三角形关系,通过拉线传感器采集单轴摇摆台复合运动中的升沉数据;同时,对惯性导航设备输出的升沉数据进行采集与处理。对测试系统输出的升沉数据进行了验证,实验结果表明:该测试系统的测试数据准确合理,可实现对惯性导航设备升沉参数的动态测试,弥补了现有同类测试系统的结构复杂、量程小等不足。

Research on Heave Data Test System of Inertial Navigation Equipment

A calibration system based on STM32 single chip and single axis swing table was developed.The calibration system utilizedtriangular relationship within a circle with fixed center and fixed radius, and collected the heave data in the composite motion of the single-axis rocking table through the wire sensor. At the same time, the calibration system collected and processed the heave data which were outputed by the inertial navigation device. The calibration system outputing heave data was verified. The test results shown that the calibration systems measurement data was accurate and reasonable. The calibration system can realize the dynamic measurement of the heave parameters of the inertial navigation device, which compensated for the shortcomings of the complex structure and small range of existing calibration systems.
