Orolia is introducing a new product for commercial aircraft safety, the Kannad Ultima-S emergency locator transmitter (ELT).

The Kannad Ultima-S is designed to be installed in the cabin of commercial aircraft or in its life raft. It is capable of notifying the crew about the launch of a search-and-rescue operation via Galileo Return Link Service (RLS).

For passengers, installation of the Kannad Ultima-S means their flight can located accurately, with rescue following if an aircraft evacuation is needed.

Orolia’s Kannad Ultima-S ELT was developed under a two-year contract through the European GNSS Agency’s Tauceti Project. Orolia says this is the first beacon to use the Galileo RLS.

Other key features include:

  • Certified to the new lithium battery regulations to avoid the risk of battery fires.
  • A multi-GNSS receiver to accept multiple signals such as GPS and Galileo to detect the aircraft’s
    location faster and deploy rescue teams sooner than before.
  • Dual activation modes: manually or automatically upon contact with water.
  • An RLS option to notify the crew that the distress signal has been received and help is on the way (available on Galileo).
  • Multiple configurations available to install in aircraft cabins and life rafts. With a rugged, compact, and easy-to-install form factor, both versions can be installed through a carry-off bag or a mounting bracket and require little storage room.

Orolia’s Kannad Ultima-S meets new and evolving EASA/FAA requirements related to ELTs and non-rechargeable lithium batteries documented under the RTCA DO-227A standard.

“Orolia is dedicated to making air travel even safer than it is today with resilient positioning and aircraft location technology, featuring automatic, manual and remote activation modes to provide a complete ELT portfolio,” said Christian Belleux, Aviation Product Line director at Orolia. “We are excited to present aircraft operators with an affordable, reliable and state-of-the-art ELT solution for cabin modifications or linefit installations.”

The new ELT benefits from the proven Cospas Sarsat infrastructure, which is being upgraded to provide highly accurate location data and nearly real-time reporting to search-and-rescue operators through global coverage.

Kannad Ultima-S survival distress beacons complement Orolia’s Ultima family of next-generation ELTs, following the company announcement of the Global Aeronautical Distress and Safety System (GADSS)-compliant fixed Ultima-DT. Orolia provides aircraft manufacturers and operators with a complete solution for every ELT application.

Orolia will exhibit at the Paris Air Show June 17-20, Hall 2B booth E32, where both new ELTs will be displayed for the first time.

On May 22, Lockheed Martin delivered the GPS III Contingency Operations (COps) software upgrade to the U.S. Air Force’s current GPS ground control system.

The upgrade will enable the Air Force to start commanding the new, next-generation GPS III satellites now coming off the production line and beginning to launch.

And the new GPS III satellites are coming. The first GPS III satellite launched in December 2018; the second GPS III shipped to Cape Canaveral in March for a July launch; and on May 17, the Air Force declared the third new GPS III “Available for Launch” next.

Ground System. The challenge was modernizing the current ground system — formally known as the GPS Architecture Evolution Plan Operational Control System (AEP OCS) — to fly the legacy constellation, as well as the new, modern GPS III satellites, until the next generation Operational Control System (OCX) Block 1, still in development, is delivered.

To address this, in 2016, the Air Force contracted Lockheed Martin to develop the GPS III COps program. Currently, the AEP OCS controls 31 GPS IIA, IIR, IIR-M and IIF satellites launched between 1993-2016. With the AEP OCS’ new GPS III COps upgrade, the Air Force will be able to command and control both the legacy satellites, as well the more powerful GPS III satellites.

“Positioning, Navigation and Timing is a critical mission for our nation and COps will allow the Air Force to gain early access to its new GPS III satellites,” said Johnathon Caldwell, Lockheed Martin’s vice president for Navigation Systems. “We just finished Final Qualification Testing and delivery on COps, and it will be integrated and installed on the AEP OCS over the summer. We look forward to the Air Force ‘flying’ a GPS constellation on the COps OCS which includes the new GPS III satellites, later this year.”

Meanwhile, the first GPS III space vehicle (GPS III SV01), launched in December 2018, is finishing up pre-operational on-orbit check-out. It continues to be controlled by OCX Block 0 software installed at Lockheed Martin’s GPS III Launch and Checkout Center at the company’s Denver facility. GPS III SV01 is expected to be “handed over” to the COps OCS later this year after the legacy constellation is moved over to the updated AEP OCS.

Lockheed Martin has sustained the AEP OCS since 2013. In November 2018, the company completed the AEP 7.5 upgrade — the largest architectural change in the systems history — replacing significant code, hardware and software to improve the system’s cybersecurity capabilities and positioning the Air Force to better operate in contested, degraded and operationally limited environments.

In December 2018, the Air Force awarded Lockheed Martin the GPS Control Segment Sustainment II (GCS II) contract to continue to further modernize and sustain the AEP OCS through 2025. In 2020, the AEP OCS is expected to receive the M-Code Early Use (MCEU) upgrade, which will allow control of M-code, an advanced, new signal designed to improve anti-jamming and anti-spoofing, as well as to increase secure access to military GPS signals for U.S. and allied armed forces.

Lockheed Martin is under contract to develop and build up to 32 GPS III/IIIF satellites. GPS III will deliver three times better accuracy and provide up to eight times improved anti-jamming capabilities. GPS III’s new L1C civil signal will make it the first GPS satellite to be interoperable with other international global navigation satellite systems. Additional “IIIF” capabilities, beginning at the 11th satellite, will include a fully digital navigation payload, Regional Military Protection, an accuracy-enhancing laser retroreflector array, and a Search & Rescue payload.
