Low-cost Mooring Location Beacon for Coastal Applications

TECHNICAL ABSTRACT: Triton Systems, Inc. proposes development of the Open-Source Oceanographic Asset Recovery Beacon (OpenORB) that will allow the deployment of coastal instrumentation moorings with affordable protection against loss. This open-source kit would significantly reduce the purchase price of a commercial location beacon by allowing the end-user to assemble a customized system with minimal time and effort. Attached to a subsurface mooring, OpenORB is capable of detecting a surfacing event and transmitting cellular or satellite signals based on network availability. Upon surfacing, the beacon activates and sends several transmissions per day for a period of 2 months to aid in the recovery of displaced moorings. While submerged, the beacon has a standby period of 8 months. The device is powered by user-replaceable AA batteries and can operate in all water environments, from temperatures of -10 to 60 degrees Celsius. OceanORB is designed for coastal applications and has a depth rating of 500 meters.SUMMARY OF ANTICIPATED RESULTS: Demonstrate beacon functionality with open-source components at an attractive price point, including modular communications capability, low power operation, a reliable surfacing detector, and a rugged design.
