What is the accuracy of your rate table?
From your test result, it is under spec.
For continuous rotation, the rate table accuracy is 0.001 dps.
I understand the error is within spec. However, as this error seems a systematic error instead of a random error, I wander if there is any configuration or future plan that can fix this.
Besides, although the nonlinearity error is samll, just imagine the following case.
1. the vehicle drives in a straight line.
2. the gyro output varies around 0dps.
3. the bias of the gyro jumps when the rate crosses 0dps.
4. this creates a bias instability much worse than the spec.
Thanks for your feedback.
1.We had test equipment and would like to do the test with yours. Could we know the detailed test steps?
2.For the Y axis value, could we know how the value of the Y axis is calculated?
The test was done in the following steps.
3.1 The gyro output was first calibrated using best fitting straight line to correct scale factor and bias error.
3. 2 The calibrated gyro output at each step was compared with the set value to calculate the error which is considered as nonlinearity.
If there is any question, pelase let me know.
From you test result, Z axis of BMI088 gyro had jump. Could we know the test result of BMI088 X, Y axis? Did them also had jump?
