1. A method comprising:

  • determining, by a tamper-proof sensor, when a target wheel'"'"'s angular rotation (Δ

    θ

    t) reaches a threshold;

    incrementing a measured count in a counter in the tamper-proof sensor in response to the rotation-determining step; and

    determining a first measured distance based on the measured count of the counter;

    determining, by an odometer, a second measured distance; and

    producing an error value based on a difference between the first measured distance and the second measured distance.
