TERRESTRIAL AIR NAVIGATION UPDATE
Also, unlike radar, ADS-B accuracy does not seriously degrade with range, atmospheric conditions, or target altitude and update intervals do not depend on the rotational speed or reliability of mechanical antennas. It provides "Radar-like" surveillance services, much like RADARĪircraft position and other data to any aircraft, or ground station equipped to receive ADS-Bįar different from radar, which works by bouncing radio waves from fixed terrestrial antennas off of airborne targets and then interpreting the reflected signals, ADS-B uses conventional Global Navigation Satellite System (GNSS) technology and a relatively simple broadcast communications link as its fundamental components. It depends on an accurate GNSS signal for position data It's always ON and requires no operator intervention
Already proven and certified as a viable low cost replacement for conventional radar, ADS-B allows pilots and air traffic controllers to "see" and control aircraft with more precision, and over a far larger percentage of the earth's surface, than has ever been possible before.

We also hope that this site will provide you with up to date information related to ADS-B and its companion technologies. Our specific goal is to show nations and commercial entities how they can quickly adapt to, and then derive a significant benefit from, this new generation of satellite intensive Air Traffic Management (ATM) systems. Its accurate and long range air-to-air capability has the potential to provide excellent collision avoidance and conflict resolution services.Its large bandwidth and robust design support bi-directional datalink (ADS-B "IN" as well as "Out").It is a proven and mature technology - it has been providing enroute radar separation, Flight Information Services (FIS) and rebroadcast Primary Radar target information services (TIS) in Alaska since 2001.It is NEXTGEN compatible, and it was the first Cooperative Dependent Surveillance (CDS) technology to be fully certified by the FAA and ICAO for critical "radar-like" air traffic control services (2002).Our Space-based ADS-B is also the only dual link (both 1090ES and UAT) system capable of tracking aircraft in real-time and with air traffic control accuracy and security, practically anywhere in the world.ĪDS-B Technologies' approach to Air Traffic Management (ATM) is based on our strong belief that we are currently entering a new era in aviation, the Global Satellite Navigation Age, in which the universal application of Global Navigation Satellite Systems (GNSS) and Automatic Dependent Surveillance - Broadcast (ADS-B), will trigger changes in global air traffic management on a scale surpassing even that which was seen during the introduction of Radar, more than sixty years ago.Īlthough we work with both 1090 MHz "Extended Squitter" and 978 MHz "UAT" ADS-B, we prefer to concentrate on 978 MHz UAT product development because we firmly believe that UAT is the most capable and flexible ADS-B datalink standard, because: Specifically, it provides support in the deployment of Automatic Dependent Surveillance - Broadcast (ADS-B) and its related Communication, Navigation, and Surveillance (CNS) technologies throughout the world.
ADS-B Technologies is an Anchorage, Alaska engineering and technical consulting firm that provides specialized air traffic management and air traffic control services.
