Embedded Inertial State Tags for Marine Asset Tracking

To provide a complete system for tracking and monitoring marine assets, the proposed effort will design an RF tag that utilizes low-cost, embedded microprocessors and accelerometers for calculating the inertial states of the container while onboard the ship. The initial states are determined at the time of loading by differential GPS measurements taken by the on-ship gateway and the in-terminal gateway. RF links from the tag to the gateway will transmit updated onboard location and sensor information for upload to control centers located onboard, in the terminals, and at remote sites. The upload frequency and real-time event threshholds are remotely programmable. The data received by the control center will be displayed in both graphical and textual views for rapid report generation and analysis.
