Hey all,
I was hoping to get some help analysing some logs. I am using just the IMU’s inside the Pixhawk 6X Pro for dead reckoning. However the drift is way more than expected. (thousands of meters in just a few minutes).
I have tried recalibrating multiple times, I’ve tried to adjust the bias values, but nothing so far has helped. I was hoping to get some help here.
This log was performed while the vehicle was stationary:
This one is performed while moving the vehicle around a bit (within a radius of ~30 cm) and eventualy putting it back where it was picked up:
The first one, where the vehicle is stationary, the estimated position of x and y is perfectly linearly moving. I would expect there to be some noise because of the dead reckoning.
The second one is a bit better, but still moving about ~3500 meters in just 2 minutes.
I am not sure what else I can try to help make the estimation more accurate, so any help would be much appriciated!
