Waiting to see if we can get this from the modem, or if we need a separate GPS.
Velocity and sensitivity is available
yippi :) .
We should try to get the GPS datasheet (exact GPS chip?) to be able to check specs.
May want to use for "true real value" a GPS RTK "in addition" if possible, if close to the coast, and RTK signal is available, accuracy is around 1cm.
(with RTK 1cm is absolute accuracy, wonder if relative accuracy may be even higher (since normal gps has typically 2.5-5m absolute accuracy, but relative accuracy may already there be much better).
Another way to test against ground truth is to use a wheel like Jim et co, but dataset of field data would still be useful anyways:)
From our discussion of today; would be possibly useful for generating test data for designing / testing custom 6dof + GPS Kalman filters:
