ClearSat-SLDMB is the next generation Self Locating Datum Marker Buoy that will replace the current USCG SLDMB with a smaller, lighter, buoy that can be deployed from an A-size sonobuoy launcher found in aircraft employed for Search and Rescue.

This GPS self-locating buoy accurately tracks the top layer of the ocean surface by reporting locations every 10 minutes in near real-time by Iridium SBD messaging. Accuracy of drift measurements are ensured because SLDMB is configured according to CODE (California Ocean Dynamic Experiment) design. This SLDMB can be rapidly delivered the site of a potential rescue operation by fixed or rotary-winged aircraft, and from vessels.

The self-deploying design of the ClearSat-SLDMB ensures it will be operational within minutes of entering the water. The drifter track from the SLDMB quantifies the movement of surface water of the search objective. Used with operational surface current models the probability of success of any rescue operation is increased by limiting the search area.
