设计了一种基于Allan方差的5阶样条拟合的方法,用于测定光纤陀螺的随机游走系数、零偏不稳定性、速率斜坡、量化噪声、速率随机游走等参数,并基于LabVIEW开发了可视化数据采集程序,对KVH公司生产的E.Core 2000型光纤陀螺进行测试。结果表明,该方法简化了光纤陀螺参数测试流程,提高了测试精度。
A fifth-order spline fitting method based on Allan variance was designed to measure parameters of random walk coefficient, bias bias instability, rate ramp, quantization noise and random walk of fiber optic gyroscope. Based on LabVIEW A visual data acquisition program was developed to test E.Core 2000 Fiber Optic Gyro manufactured by KVH. The results show that this method simplifies the testing process of fiber optic gyroscope parameters and improves the testing accuracy.
