Innovative and cost-effective remote sensing solutions. OTR-300 Drifter Buoy The low profile 300 buoy series from Ocean Trek Research is a rugged and extensible buoy design, available with a number of standard or customizable sensor configurations. The 300 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...) Both internal and external sensors can be accommodated.
