ADIS16488 Bias Optimization

Hi Matt,

I am working with the ADIS16488 for an application that is similar to the one mentioned above.

Our application is integrating the gyros over time. I am trying to compensate for the effect of the Earth's rotation on the sensor.

 

I have tried various sample sizes to attempt to eliminate the bias error.

The data that we are getting from stationary tests show that the uncompensated gyro drift is approximatly 30-40 degrees per hour. From the datasheet I was expecting about 6 or 7 degrees per hour.

 

Is there an optimum bias sample window  to eliminate the bias error?

 

Thanks,

Rich
