The MetOcean Iridium SLDMB (iSLDMB) is an innovative rugged compact A-size Self Locating Datum Marker Buoy. The iSLDMB was designed and tested to meet the stringent performance requirements of coastguards for Search and Rescue (SAR) operations in the open ocean. The iSLDMB design is based on the proven CODE/Davis style oceanographic surface drifters.
The inexpensive expendable drifter is equipped with an Iridium bi-directional satellite transmitter, sea surface temperature sensor, and a GPS receiver. Due to the urgency of SAR situations, the iSLDMB is able to communicate critical data within real-time to the end-user. Robustly designed, the iSLDMB is air certified and can be deployed with ease from helicopters, ships, fixed wing and rotary wing aircraft. The drifter’s operating life is between 15-120* days depending on the required data transmission rate.
