Hi Steve:
It's my understanding that they do have baro altimeters, gyros and
accelerometers plus some other flight stability inputs.
But . . . they seem to be vulnerable to some forms of GPS jamming or spoofing.
If jamming started out with the same satellite positions as were currently in the
I can't imagine that we don't sanity check without baro , altimeters . Isn't
that the inspiration
for the Kalman filter ?
