An estimate of the peer device's position produced from the sensor fusion algorithm.
The angles are the angle to the peer in the local device frame, that is, this device's Android Sensor Coordinate System. This differs from the boresight-relative angle of arrival measured by the UWB hardware and reported by a standard ranging session, see RangingPosition.

Public properties
azimuth
val azimuth: RangingMeasurement?
The azimuth angle in degrees ([-180, 180]) of the ranging device, or null if not available. The angle is measured about the device's Z axis starting from its Y axis, the top edge of the device, and is positive clockwise when viewed from the front of the screen, so a positive azimuth means the peer is to the right of the device.
distance
val distance: RangingMeasurement
The line-of-sight distance in meters of the ranging device.
elapsedRealtimeNanos
val elapsedRealtimeNanos: Long
The elapsed realtime in nanos from when the system booted up to this position estimate.
elevation
val elevation: RangingMeasurement?
The elevation angle in degrees ([-90, 90]) of the ranging device, or null if not available. The angle is measured out of the device's XY plane and is positive towards the device's Z axis, so a positive elevation means the peer is towards the front of the screen.
