This read-only value, in degrees, reports the compass direction the GPS receiver is or should be moving toward, as determined by the last location fix. An admin tracking a mobile cellular-equipped asset uses this to confirm the direction of travel, useful for fleet monitoring or verifying a vehicle is moving along an expected route. For example, if a delivery vehicle's router should be heading north along a highway but this object reports a heading of 180 degrees, the admin might flag the route as unexpected.
