The best ones, like in my drone use all of the mentioned ones in duplicate as well as a barometric sensor, echolocation, IR sensors, and cameras for object identification, etc. It takes a LOT of data and processing for a machine to know where it's at and what it is doing.
Thanks for the info on this. I was starting to think the unit may be defective... I have the 8.1 screen from 4x4 shop Canada
