McMurdo Group
Lanham, MD

McMurdo Group, a company that specializes in end-to-end search and rescue (SAR) and maritime domain awareness (MDA) solutions, was recently selected by Embraer to provide complete Emergency Locator Transmitter (ELT) shipsets for its E Jets second generation of aircraft, known as the E Jets E2. The contract will include McMurdo Group’s Kannad Integra ELTs with its new ARINC GPS Interface fitted on the aircraft, and Kannad 406 MHz Survival ELTs for use by crewmembers in the cabin.

The ELTs will be installed in various Embraer E Jets E2s, including the E175 E2, E190 E2, and E195 E2 versions, starting in 2018. Kannad Aviation ELTs are already integrated into Embraer’s existing Phenom 100, Phenom 300, Legacy 450 and Legacy 500 business jet aircrafts, and are used by some of the world’s largest aircraft and airline brands including Airbus, Boeing, Bombardier, Pilatus, British Airways, China Airlines and United Airlines.

The Kannad Aviation ELTs are currently the only ELTs with a dual positioning source: the GPS receiver on board the aircraft and an internal GPS receiver integrated into the beacon. The Kannad Integra ARINC e-Nav interface allows the GPS position of an aircraft to be transmitted continuously from the onboard GPS to the beacon. This allows the ELT to store and record the aircraft's position information in real time. In addition, the ELT also has an internal GPS receiver.

The Kannad Integra-AF provides several performance advantages due to its redundant antenna and GPS interface designs. Unlike traditional ELTs, Integra Kannad ELTs have a secondary built-in antenna that will continue to transmit distress signals in the event the primary external antenna is non-functional during a crash. A dual GPS design includes a built in GPS antenna and a connection to standard onboard GPS systems to further facilitate emergency location positioning. Other Kannad benefits, such as its compact, lightweight design and easy programming, also factored into Embraer’s decision.

In a typical search and rescue scenario, an emergency signal from an ELT or distress beacon is relayed via satellite to Mission Control Centers and Rescue Coordination Centers for eventual rescue team deployment. This search and rescue ecosystem (known as COSPAS ARSAT) has helped to save over 37,000 lives since 1982.
