the relevant queue to provide data. Also disable the quaternion stabilization
flag.

Change how we convert LLA to NED. Now it is done with a taylor expansion

around the home LLA coordinate to avoid the conversion into ECEF coordinates.
This has the benefit of not requiring double precision math and uses less
