惯性传感器在导航系统中应用广泛,为了保证上述给定应用的适应性及满足应用的精度要求,需要对传感器进行必要的性能参数实验研究。以ADI公司的ADIS16355惯性传感器为研究对象,首先介绍它在导航中的应用及其数据读取基本操作;接着介绍SGT320E型三轴多功能转台,通过该转台进行了ADIS16355传感器固定零偏、标度因数、标度因数非线性及长期稳定性性能指标的实验,应用Matlab软件对传感器输出数据进行分析。详细介绍了实验步骤及实验结果分析,结果表明ADIS16355XYZ轴陀螺仪固定零偏、标度因数符合其数据手册指标。

Inertial sensor is important for navigation applications. In this paper, the integrated inertial sensor of ADI＇s ADIS16355 was studied experimentally with a three-axis turntable SGT320E. After a brief introduction of its application in navigation and basic IO operations about data reading and processing, procedures were presented to test ADIS16355 in terms of sensor bias, scale factor, scale factor linearity and long-term stability performances, which led to establishing of its output model. The experiment data with the three-axis turntable was analyzed using Matlab and it was shown that the ADIS16355 XYZ axis static gyro drift and scale factors were in agreement with its datasheet.
