I was working with the robot_localization package for fusing encoder/IMU/GPS measurements. I wanted to know does the filter fuse the measurements in time? Is it a loosely-coupled fusion? It would be helpful if someone can explain the underlying algorithm for taking in the measurements for correction.
Take a look at the documentation. That has a global overview of how things work, a link to the ROSCon15 talk by Tom and a reference to a paper describing the component.
Thanks. I actually wanted some clarity/confirmation whether any sort of coupling happens between the measurements and their covariances before they are used for correction in the filter?
