A nice discussion of inertial navigation capability (https://news.ycombinator.com/item?id=10752294):

    Consumer grade MEMS ...are not sufficient for intertial navigation, ... 

    At around the $2K-30K you get systems that can 
    provide accurate navigation for up to 2 minutes or so. 

    Aviation grade IMUs ... maximum horizontal position drift of 1.5km 
    in the first hour of operation. These will run 100K and up.

One uses inertial systems to cover for disruptions in service of the other systems.
