I think you just closed the thread, ADXRS 453 null bias stability . and i wanna ask here if you don't mind.
The null value is so critical when we want to obtain "Angular position" from "angular velocity" by integrating over time.
Small Null value (for example 0.5 degree per sec that mentioned in datasheet in Null Accuracy section) will cause 1 degree error in 2 sec !!! And my research shows there is no way except integrating over time for obtaining angular position from MEMS gyroscopes.
Please let me know if you suggest any method for solving this problem.
Looking forward to hearing from you.
