Collecting Wave Data in Storms

QinetiQ North America’s Micro Air-Launched Expendable Wave Buoy (MAXWB) is designed for short-term deployments in near-shore or deep-water environments. Deployable from any aircraft or boat, the MAXWB is designed to collect wave data in storms and hurricanes where conventional gauges may be difficult to deploy.

MAXWB measures near real-time, non-directional wave data including significant wave height, dominant wave period, average wave period, non-directional wave spectra and sea surface temperature. From an aircraft, it can be hand deployed or ejected from a standard military Countermeasures Dispenser System (CMDS) using an explosive squib.

MAXWB conforms to standard MJU-10B flare countermeasure dimensions of 5.0 x 6.4 x 20.0 cm (2.0 x 2.5 x 8.0 inches). Upon ejection, the upper part of the packaging falls away as it free-falls to the ocean surface, allowing the flotation/ stabilizers and data communications antenna to deploy.

MAXWB electronics consist of a single vertically oriented, micro-machined accelerometer, a temperature sensor, a microcomputer for data acquisition and processing, and a UHF transmitter (400 to 406 MHz) powered by lithium batteries. The transmitted data is recorded and displayed by a UHF receiver and laptop PC located in the launch aircraft, boat or with any line-of-sight observer.
