And with the development of the Internet of Things and machine-to-machine interfacing, the potential value that could be unlocked in global supply chains is significant, according to this think piece in Maritime Executive. “Commercial customers on the other hand are realising the potential of satellite AIS to shed light into the critical ocean segment of global trade and logistics operations, running the gamut from tracking energy and commodity shipments to container vessels hauling consumer and industrial goods.”
