MetOcean Wins USCG Contract to Supply SAR Buoy

MetOcean Telematics (MetOcean) won a five-year blanket purchase agreement (BPA) to supply the United States Coast Guard (USCG) with its  search and rescue buoy, the Iridium Self Locating Datum Marker Buoy, also known as the iSLDMB.The United States Coast Guard is a a core-user of the iSLDMB, and during an active SAR event, the MetOcean iSLDMB allows Coast Guardsto quickly travel to the event location via aircraft and then deploy the buoys by air in the region of interest, helping to significantly reduce overall search time. Each buoy provides vital real-time data at the top 1 meter of the

NASA’s JPL Using Teledyne Marine APEX Profiling Floats

Teledyne Marine announced the recent sale and deployment of three APEX profiling floats to NASA’s Jet Propulsion Laboratory in Southern California. The three floats were equipped with RBR CTD sensors, Short-Burst-Data for communication over the Iridium Satellite Network, and special parachutes for air deployment.  The rise in global sea levels will be a major environmental challenge for the 21st Century. For this reason, it is of increasing importance that we improve our methods and understanding for predicting this process. A recent major initiative to do this has been led by JPL Scientist

returns at multiple ultrasonic frequencies.The buoy has solar panels and a set of rechargeable and non-rechargeable backup batteries. In the summer, when there is abundant solar power, the buoy will sample for 20 minutes every two hours, limited by the amount of data that can be transferred via the Iridium satellite modem connection. In the winter, the buoy will sample for six minutes every three hours, limited mostly by available backup battery capacity. This satellite link is bi-directional allowing for the downloading of data as well as the ability to reconfigure instrument parameters remotely

The 12 buoys are set up to communicate via Iridium Short Burst Data (SBD) with an onboard Global System for Mobile Communications (GSM) option to further reduce operational costs when the buoys are moved closer inshore as the project progresses.OSIL said data from the buoys can be fed directly into the client servers via Iridium SBD, and the client'

for land bombardment ranges and the necessity to destroy physical targets on land or at sea.The free-floating system consists of a set of operation buoys, which report acoustic event data, point of impact, and precise time. The acoustic event data is sent to a base station receiver using overthe-horizon Iridium satellite telemetry or UHF line-of-sight radio, this allows MASS to measure indirect fire. Real-time results are viewed and analyzed both on-ship and at land-based command posts.“MASS is the future of naval gunfire training,” said Tony Chedrawy, President & CEO, MetOcean Telematics

, although acceptance and use for growing applications are starting to accelerate,” says Burnett.For this project, the 5m-long AutoNaut system was chosen. The Islay AutoNaut was equipped with a 25m-long two-channel towed hydrophone array and a hull-mounted PAM. It had 1,800 m line of sight control, iridium communications and Wi-fi data access for wireless data transfer at sea. “It has quiet wave-foil propulsion to minimise contamination of the data, needs zero fuel because it harvests energy from waves to move forward and proven command and control,” says Burnett. It could be monitored

New Drifter Buoy Tracks Water Currents

MetOcean Telematics has developed the STOKES Iridium tracking drifter, a compact drifting buoy designed and tested in technical partnership with Florida State University (FSU) that tracks water currents at the surface.The small light-weight buoy is equipped with Iridium satellite telemetry, GPS positioning and a sea surface temperature sensor. Iridium satellite telemetry enables the buoy to provide vital sensor and geo-positional location data in real time. Iridium also allows the buoy to have bi-directional capabilities. This is a critical ability, for example, if the buoy enters a region of interest
