interaction.

data that is all zeros although we shouldn't see this.

little aggressive. Also increased the drift rate of the gyro bias per Sambas'
testing (thanks) although not to the levels required for flying through 40 deg
C transitions.
Made the dump_ekf function handle both numbers of states

from the AHRS code (which will facilitate code integration with new INS) and
also will help set up a fifo queue for the downsampled data to allow gyro data
output from AHRS faster than EKF output. Also decreased ADC interrupt priority
so the SPI comms don't drop out.

bias correction. This is useful for stabilization to get rid of the gyro bias.
Making it an option is important for calibration.

Three files added to AHRS which add accelerometer biases (16 states) to the INS/GPS. Added for evaluation (give it a try James).

in practice I need this.

Increased default value to 0.4 to better reflect the GPS accuracy.

track offset between GPS and baro in outdoor mode.

Changes in ahrs.c for new initialization and to fix issues with outdoor algorithm. The changes in ahrs.c are pretty messy, but committed mostly to get the code to Peabody for more extensive restructuring of ahrs.c.

1) Moved the criteria for using GPS to defines in anticipation of moving into
AHRSSettings
2) Only use the mags for updates if the vector length is within 20% of nominal
to avoid updating when it's nonsense
3) Reinitialize position when swapping between indoor and outdoor
4) Dont use mags for first 5 seconds after initialization, sometimes seems to
cause issues
5) Dont use mags until magnetic field at your location is set and a magnetic
field is loaded
6) Dont use GPS if home location hasnt been set

moved around where the axis are swapped and made the negative sign come from
calibration.
