Bias Null Command in ADIS16488A

Dear Friends,


This question is mainly for the Analog engineers who work on IMUs.


We are evaluating one of the IMU sensors - ADIS16488A.

There is a command 'Bias Null Command' which averages data for some time (~26 sec) and removes the average value as bias.

My doubt is if we enable the bias correction factor for Accelerometers, are we not removing the initial attitude also as bias?

If yes, how can we use this command/what is the purpose of this command?


Thanks in advance.
