T have been doing a route past the airport and back that has pretty large

installed a wheel sensor on the bike and added it to the sensor group.
The 25 mile route came in at 27 miles. Now upon occasion it showed that
distance on straight GPS but it appears that civilian GPS is pretty easy to interfere with.

I use GPS only, but even so very minimal deviations certainly not into

This only occurs around the airport and not up in the hills. So I think that it is due to radio interference.
