Basically, I’m building a Rover which can localize in GPS Denied Regions.
So, initially i though this work can be done by using GPS and IMU.
But found that integrating the data of IMU generates errors and it drifts too.
Use of camera-based localisation is not possible since the environment is not known.
So are there any other sensors through which this can be done?
Or is there any other approach for the same?
