Hello I am working on a gazebo model where I am trying to update my IMU and GPS uncertainties to match the pixhawk 4.
For my model I am looking for four main paramaters for both the gyroscope and accelerometer portion of the IMU. The Noise Density (which is provided in the tech sheets), the random walk, the bias correlation time, and the turn on biass sigma.
I was wondering, does anyone already have these values and is willing to share them? Or can I get these values from the tech sheets of the IMU’s (I am not EE or electronics expert so I don’t really know what I am looking at in the tech sheet). I know I can do this experimentally by turning the pixhawk 4 on for a while, log it sitting still and analyzing the data logged by the IMU but would prefer not to do it this experimental way.
