latency to about half the window size. -->

elevation. This helps produce better predictions from pose changes, and improves the quality
of the AoA primer. -->

<!-- Selects which pose source will be used by default to anticipate the next UWB measurement.
The pose source helps lower latency by shifting the filter states to reflect how the phone has
moved.
NONE = No pose source.
ROTATION_VECTOR = Requires gyro, accel and compass. Very accurate, rotation only.
GYRO = Gyro only. Less accurate, Saves a tiny bit of power.
SIXDOF = 6DOF sensor. Extremely accurate, accounts for position. Not available on most hardware.
DOUBLE_INTEGRATE = Double integration. Under development. Expect very bad motion drift.

<!-- Sets the field of view, in degrees. Note that this is in degrees from 0 (straight ahead),
which is not the same as how camera FOV is represented.
UWB values outside the field of view will be replaced with predicted values based on pose
changes. The FOV is circular, so a value of 90 will only provide continuous azimuth values if
elevation is zero.
If <=0 or >=180, the primer will be disabled, allowing an unlimited field of view. -->
<integer name="primer_fov_degrees">0</integer>
<!-- Enables the back azimuth primer. This is needed on hardware that does not report azimuth
values beyond +/-90deg. This primer determines if azimuth values are likely to be coming from
behind the phone in three ways:
1. The prediction expects the next reading to come from behind the user because the user has
rotated away from the signal.
2. Predictions based on pose changes inversely correlate with azimuth readings.
3. UWB readings show very little relationship to pose changes because of non-line-of-sight
conditions.
This works best with an FOV primer setting below 90 degrees to ensure that predictions are being
used across the 90-degree threshold. -->
