ADS-B Technologies Successfully Tests NextGen Air Traffic Surveillance Using The Globalstar Satellite Network
ADS-B Technologies, LLC has announced the completion of the first public demonstration of its revolutionary space-based Automatic Dependent Surveillance-Broadcast (ADS-B) air traffic control surveillance system in the deep mountain passes of Alaska. The tests, conducted during the third week in April demonstrated conclusively that highly accurate, reliable and low latency surveillance is now possible at any altitude and over any terrain from virtually anywhere on earth.
"We chose the worst possible conditions for the test, assuming that if we could prove that an aircraft could be reliably tracked only a few hundred feet off the ground in a four thousand foot deep mountain pass, then it could be tracked just about anywhere else on earth," said Skip Nelson, ADS-B Technologies´ president. "The data that we collected from two aircraft - sometimes flying in close formation - clearly demonstrates that we have a viable system. Over-the-horizon, or space-based ADS-B is now a reality."
The new technology is called the ADS-B Link Augmentation System, or "ALAS". It is a true over-the-horizon air traffic surveillance system capable of delivering an uncorrupted 1090ES or UAT payload to an Air Traffic Control (ATC) automation system in real-time from remote, oceanic, or mountainous areas where a conventional line of sight connection to a terrestrial ADS-B ground station is either impossible, or impractical. ALAS is also designed to be unobtrusive and subordinate to conventional line of sight ADS-B and therefore will not interfere with normal payload delivery to other aircraft and to ground stations.
ADS-B Technologies has partnered with Globalstar, Inc. (NASDAQ:GSAT), a world leader in satellite communications, to transmit the air traffic control data between the aircraft and its strategically placed satellite ground stations around the world. "We definitely prefer Globalstar´s relatively simple and straightforward "bent pipe" architecture for a safety centric business like air traffic surveillance," commented Mike Melum, ADS-B Technologies´ Chief Scientist. "There are fewer potential points of failure and so far, we see no technical barrier to tracking more than 3,000 aircraft in a roughly 1,000 mile diameter footprint from each Globalstar satellite. And, since all of the "brains" of the system remain on the ground rather than on satellites in space, maintenance, expansion and future modifications are going to be much easier and more economical to accomplish."
ALAS is designed to be a simple, economical and easily installed after market enhancement to virtually any 1090 MHz or 978 MHz ADS-B avionics source. User costs, some of which will be borne by the Air Navigation Service Providers and some by the aircraft operators themselves, are forecast to be significantly lower than the current rates associated with similar, yet less capable services like ADS-C.
"With Globalstar´s unique bent-pipe architecture, ground stations can be located close to air traffic control facilities in nations around the world," Nelson said. "This is not only safer and more efficient, but a nation´s ability to land its own ADS-B data within its own borders at a reasonable cost will encourage global harmonization and perhaps earlier worldwide adoption of ADS-B as a universal surveillance standard."
ALAS has been in development since 2009 and a fully certified version of the product is expected to be ready for market by mid 2014. Globalstar has already launched 18 of its 24 next generation low earth orbit (LEO) satellites and should be capable of covering most of the world´s busiest air routes by 2015. Full worldwide coverage, including north polar could be possible by 2017.

ADS-Technologies Responds to FAA NextGen Space - Based Air Traffic Control Provider Search
ADS-B Technologies recently responded to an FAA market survey request that would identify vendors who could provide a space-based Automatic Dependent Surveillance - Broadcast (ADS-B) service for remote mountainous areas in the US and in oceanic regions starting in 2018.
These systems would augment the FAA´s domestic ground-based ADS-B infrastructure, set to be operational as early as 2013 with full implementation in 2020.
The proposed ADS-B Technologies system would use the Globalstar (NASDAQ:GSAT) Second Generation Low Earth Orbit constellation and the Company´s proprietary ADS-B Link Augmentation System (ALAS™) avionics interface to provide real time aircraft position information to the FAA. The system has been designed to augment existing terrestrial systems by allowing aircraft to be precisely tracked by controllers in areas where conventional surveillance methods are either impossible or impractical to employ. In addition to FAA tracking, individual aircraft could be equipped to see each other and receive real time weather and airspace information from authorized sources on the ground.
On December 28, six more second-generation Globalstar satellites were successfully launched from the Baikonur Cosmodrome in Kazakhstan, using the Soyuz launch vehicle. This was Globalstar´s third successful multi-satellite launch in a little more than a year.
"This means that Globalstar is now three-quarters of the way toward its goal of launching 24 new high speed, high capacity satellites capable of supporting our NextGen space based air traffic management system," said Skip Nelson, president of ADS-B Technologies LLC. "And it also means that we are on track for full scale operational testing by late 2014, should the FAA or any other civil aviation organization require it."
The unique combination of the ALAS avionics interface and Globalstar´s relatively straight forward and reliable "bent pipe" architecture will allow virtually any 1090 MHz Extended Squitter (ES) or 978 Megahertz Universal Access Transceiver ADS-B source to report an aircraft´s position to ATC in real-time (<400ms). An additional advantage of the Globalstar system is that all of the unique ADS-B components remain on the ground where repairs and upgrades are easily accomplished.
"Simplicity may be the key to establishing the kind of reliability that a safety-oriented business like air traffic control requires," Nelson said. "Globalstar´s large number of ground stations means fewer and shorter hops between the satellite and the ATC point of service and thus fewer potential points of failure. This should also promote global harmonization since it also means that more nations will be able to land their own surveillance data inside their own borders with a standardized set of protocols."

ADS-B Technologies and Globalstar Connect to Create Worldwide Air Traffic Network
To help meet the NextGen agenda for air traffic management, ADS-B Technologies LLC has teamed with Globalstar, Inc. to develop a worldwide leading edge satellite based air traffic control management system.
On July 13 six new second-generation Globalstar satellites were successfully launched from the Baikonur Cosmodrome in Kazakhstan, using the Soyuz launch vehicle. "This means that Globalstar is halfway to its goal of adding 24 new second-generation satellites to its constellation,"said Robert "Skip" Nelson president of ADS-B Technologies LLC. "And with these new satellites, ADS-B Technologies is now almost halfway to our goal of creating a system that can someday provide satellite based ADS-B on a global scale."
ADS-B Technologies now has a formal 10-year agreement with Globalstar, Inc. (NASDAQ:GSAT), announced on May 10, 2011 to use its proprietary ADS-B Link Augmentation System ALAS™ technology on Globalstar´s Second - Generation satellite constellation. The ALAS™ system, which will use Globalstar´s network of satellites and ground stations to provide both ADS-B surveillance and communications services on a global scale, was first announced to the public at the Integrated Communications, Navigation and Surveillance Conference in Herndon, VA in May 2010.
"The system will be compatible with virtually any 978 Megahertz Universal Access Transceiver, or 1090 MHz Extended Squitter (ES) ADS-B avionics source," Nelson said. "The higher data transfer rate that Globalstar´s new constellation will provide is absolutely necessary for ADS-B link augmentation."
The ALAS™ system is designed to augment existing ADS-B networks commissioned by the Federal Aviation Administration as well as systems in Australia and Europe to create trans-oceanic and remote services well out of the range of conventional ground based networks. It also has the potential to offer the real-time backhaul of Flight Data Recorder information, UAS sensor data, bi-directional meteorological data and bi-directional voice in a wide range of avionics and air traffic management applications.
According to ADS-B Technologies Director, Dr. Fred Fish, "So far, industry response and peer reviews have been quite positive. Airborne testing and the certification process will continue for another year or so and we´re on schedule for an initial commercial demonstration sometime in mid-2013."

Technologies Unveils Satellite Hosted ADS-B Link
Augmentation System (ALAS)
ADS-B Technologies introduced its new Automatic
Dependent Surveillance - Broadcast peripheral system
called the ADS-B Link Augmentation System, or
ALAS™ at the 2010 ICNS Conference in Herndon, Va
last week. The Patent Pending system enables aircraft
to maintain non-line-of-sight air-to-ground
surveillance, data, and voice communication on a
world-wide basis and in real-time as a supplement to
primary line-of-sight (LOS) ground-based ADS-B systems.
ALAS uses MOPS compliant 978MHz ADS-B technology and
voice communications via a proprietary Low Earth Orbit
(LEO) satellite link on a non-interference basis with
primary LOS ground-based surveillance, data and voice
Current primary data communication systems are
dependent upon ground-based transceivers to convey a
variety of information, including surveillance and
voice for Air Traffic Control, weather data, and
operator communications. These air/ground radio
frequency links are, in most cases, limited to direct
LOS communication. Mountain ranges, expansive open
water and the curvature of the earth all limit the
effective range of conventional systems to relatively
short distances and those aircraft beyond LOS range
frequently fly without the benefits of high fidelity
surveillance. While many international transport
category aircraft do use non-LOS links such as the
FANS-1 and ADS-C, operations utilizing these systems
are necessarily constrained to “procedural”
aircraft-to-aircraft separation spacing, rather than
more efficient surveillance separation spacing, based
largely on the limitations of the functional
architecture supporting those systems.
ALAS now provides a way to extend the surveillance
and communications capabilities of current NextGen
ADS-B networks to very remote, or oceanic areas beyond
the practical capabilities of systems with terrestrial
antennas. Primarily designed to support the
bi-directional 978MHz UAT link protocol, the system can
be used with the 1090MHz Extended Squitter link as
well. An important feature of the ALAS system is that
it is designed to work as a peripheral device and is
thus compatible with almost any ADS-B avionics or
Ground Based Transceiver system. Bi-directional link
encryption is not only possible, but also somewhat
inherent due to the system's design.
The system has been in development and airborne
testing for more than three years. Globalstar, Inc.
will provide the satellite backbone for the technology.
Evaluation units should become available no later than
4th Quarter 2011.
