Globalstar demonstrates 7,000m dual-link space-based ADS-B

311182-2Globalstar and its partner, ADS-B Technologies, have completed the latest public flight demonstration showcasing their space-based ADS-B Link Augmentation System (ALAS).

This test, embarking from Alaska to the Gulf of Mexico and back, marked the first time that a flight demonstration tested a dual-link space-based ADS-B system in all environments and for extended periods of time. The flight proved that the 1090ES and UAT versions of the ALAS technology work continuously, reporting the aircraft’s position every second during a flight of nearly 7,000 miles.

“We are very pleased with the outcome of this latest flight demonstration,” said Jay Monroe, chairman and CEO of Globalstar. “With this test, we have proven that Globalstar can provide a very secure, reliable and low latency platform for space-based tracking of aircraft in real time. Further, with our unique architecture and scalable capacity, the ALAS system will eventually be able to track aircraft virtually anywhere on earth.

“ALAS technology works in places where there are known gaps in flight tracking ability, like the Gulf of Mexico. This test shows that once certification is received, ALAS can be easily installed as a peripheral to virtually any existing 1090 MHz or 978 MHz avionics source and used to track flights within our current and future global footprint down to the second. Recent aviation events have proven that this technology is needed now more than ever.”

“ALAS may also be a more secure form of ADS-B, since the nature of the L-Band transmission and the antenna pattern make the aircraft’s ADS-B position reports extremely difficult to intercept, jam or deceive,” added Monroe.

The 7,000 mile roundtrip flight was designed to highlight the capabilities of the ALAS technology to provide continuous tracking, even in areas where standard ADS-B avionics would not be able to report.  “This flight clearly demonstrated the robustness of the ALAS system, and its viability as an immediate solution for tracking aircraft virtually anywhere at any time,” said Skip Nelson, ADS-B Technologies´ president.

“We’ve been working tirelessly on tracking solutions since the loss of Air France 447 in 2009 in hopes that one day, missing aircraft will be a thing of the past.  As our tracking map clearly demonstrates, we believe that day has finally arrived.”
