The ClearSat-1 surface drifter accurately follows the upper 1 meter of the ocean to measure velocity and provide a platform for oceanographic measurements. It is configured according to CODE (California Ocean Dynamic Experiment) specifications that minimize effects of wind and waves on buoy trajectory.

Drifter hull and spars are constructed of black-anodized, corrosion-resistant 5061 aluminum. Polyethylene–backed polypropylene sails are tough and resist fraying. Redundant o-ring seals protect drifter components to greater than 1 atm. (>10 meters). Spring-loaded spars and a spring-mounted antenna ensure the drifter is easily assembled for use, repacked, or that it automatically unfolds when dropped from an aircraft or a vessel in self-deployment packaging.

The ClearSat-1 is powered by our versatile, power-saving Clearsat-4.1 controller. Data are reported worldwide by satellite telemetry through the Argos system, which also accurately locates the drifter’s position. Iridium SBD data communication is also available. GPS option required for self-location.
