ocean trek research Innovative and cost-effective remote sensing solutions. OTR-600 Air-deployable Buoy The small 600 buoy series from Ocean Trek Research is designed to fit inside a small unmanned aircraft (www. atiak.com) where it can be autonomously released, either upon detection of a target in the water or at a predetermined location. While originally conceived to act as a “marker” for tracking the movement of marine debris, the design is adaptable for a variety of uses including deployment by hand. Roughly the size of a grapefruit, the 600 series uses the Inmarsat satellite network for bi-directional communications. The end-user interacts with the buoy via a personal and secure web page; where buoy data can be viewed on an interactive map and a series of commands can be sent to the buoy (e.g. alter the reporting frequency, poll for position, turn a sensor or light on…) Due to the size, limited internal and external sensors can be accommodated.
