Buoys
Specializing in the marine environment, Datawell developed the basic principles of the gravity stabilized long period motion sensors. That, in combination with designs for very low power electronics, resulted in the Waverider (1968), the Wavec buoy (1983) and Directional Waverider buoy (1988).
