Abstract: The present invention provides a system, method and apparatus for determining the status of coupled assets during transport. According to a first preferred embodiment, a method of the present invention preferably includes triggering a set of tracking devices to transmit time stamp data indicating when the tracked assets cross pre-set speed thresholds. The present invention preferably further includes comparing the received time stamp data to equivalent data points from other assets and identifying unique pairs of assets which crossed the same speed thresholds at similar times and positions (i.e. matching velocity profiles). The system then designates the unique pair of assets as coupled and may apply custom tracking rules and power saving algorithms to the coupled assets.
