You don't double integrate, period. You essentially have three options:
1) An absolute positioning system like GPS.
2) A visual positioning system like fiducial markers or SLAM.
3) Something that can measure linear speed and then you integrate the speed only once. Easy to do on vehicles, but even the most accurate system will quickly drift.
