RJE Int STI 350Irvine, CA July 14 2016 - RJE International’s STI-350 Surface Acoustic Receiver System was successfully used in the recovery of an Airbus CASA C-212 Aviocar 400 sea patrol plane. The Vietnamese Coast Guard CASA 212 and crew of 9 was answering a distress call of a SU30-MK2 fighter Jet that crashed on a training mission earlier, when the search plane also crashed due to bad weather.

The CASA 212 was located at a depth of 50-60 meters under the sea, south east of Back Long Vi island in the Gulf of Tonkin. The search included efforts from the Vietnamese Navy, Coast Guard, Air Force and local fisheries searching for the crew and black box from the CASA. The Vietnam Minister of Defense issued confirmation that they quickly pinpointed the exact location of the plane, in part to the STI-350 Surface Acoustic Receiver System. The Minister of Defense and Airbus will work together to analyze the wreckage and determine the cause of the incident and will focus on the recovery of the last crew member.

Robert Jechart, CEO of RJE International stated “It’s always unfortunate to hear of a crash, but knowing RJE can aid during this crucial time to successfully locate an aircraft and provide answers is critical. Locating the aircraft quickly allows the operator to determine what happened. Most importantly, it provides the opportunity to learn and make improvements to prevent this from happening again. It is also critical to bring resolution to families who are struggling with the unknown fate of a loved one.

The STI-350 Surface Acoustic Receiver is a compact and rugged battery operated directional receiver that detects and tracks underwater pingers (beacons) as well as transponders from the surface.

McGill-photo-for-website7/2015 - RJE International donated an underwater locator beacon to the engineering design team of McGill Robotics of Quebec, Canada. The team is competing at an event organized by AUVSI Foundation and the Office of Naval Research in San Diego, CA.

Adrian Battiston, Mechanical Leader and Project Manager accepted the beacon from Robert Jechart, President of RJE International. By supporting McGill we are directly supporting education of over 50 engineering students.

RJE International, continues its mission of giving back to the community and supporting research and education. These underwater locator beacons, previously used on aircraft black boxes, have been repurposed and donated for research. The beacons meet rigid standards and are equipped with new 30 day batteries.

Irvine, CA September 23rd 2016 - RJE International, has been working with top Oceanography, Robotics and Engineering Programs and Universities across the U.S. for the past year. By gifting product through their Educational Program, we have been able to aid in furthering their studies and explorations. A portion of these studies include: monitoring the arctic ice sheets and Kelp Forest in the Aleutian Islands with the University of Alaska, fracture zones and volcanic sediment with the University of Hawaii, being able to earlier predict hurricanes with the University of Maryland, California Coast eco and sea floor mapping with UC San Diego.

CEO, Robert Jechart stated “Not only is it important to give back to our industry, but it’s equally important to inspire our future scientist and engineers. We're excited RJE is part of new scientific developments and research that furthers a greater education of our planet.” The initial program re-purposed aircraft black box beacons. By being eco-conscious and recycling the RJE beacons, they provided new life to projects that often lacked adequate funds and equipment. This resulted in 13 Universities receiving valuable RJE products that enabled them to continue their research. The RJE ELP-360R Underwater Locator Beacon was widely used in the various school’s programs.

"Last year CUAUV updated our acoustic subsystems with a newly redesigned board for acoustic signal conditioning and a new software DSP stack. RJE's underwater locator beacon was an indispensable tool for testing this new system because it allowed us to accurately test in the pool in Ithaca with a beacon that was very similar to what we expected to find at the competition. As a result, when we got to the competition in San Diego we were able to immediately start tracking the competition's locator beacons and did not have to re-calibrate our acoustics system. This would not have been possible without RJE's pinger and having this hardware was a major contributor to our success." said Noah Levy, Cornell University Hydrophones Lead.
