Analytical ADS-B Data

Aireon’s space-based Automatic Dependent Surveillance-Broadcast (ADS-B) system will create an archive of aircraft location and movements of all ADS-B equipped aircraft worldwide.  Aireon’s global database of precise real-time aircraft data will be a repository of information to support stakeholder analysis and reporting of aviation trends and performance.

Data Limitations
Current aviation data suffers from several limitations.  Aviation data sets are stitched together using many regional or country sources.  These sources use different technologies and systems to assemble the aircraft movement data. Primary and secondary radars, land-based ADS-B and Wide Area Multilateration (WAM) are confined to line-of-sight surveillance in densely populated areas. Automatic Dependent Surveillance – Contract (ADS-C) also has limited utility due to incomplete aircraft equipage and infrequent position update rates (typically 10 to 18 minutes).

As a result, existing data sources do not offer a complete or single picture and often have significant gaps in fleet data, regional limitations in unique Flight Information Regions (FIRs) and incomplete data across major air traffic routes.  Most airspace analysis is done with less-than-accurate assumptions and relies on scheduled information and flight plans, rather than actual routes and diversions, which often differ from the original plan when the realities of traffic congestion and weather events intercede.

The Aireon Solution
Starting in 2018, Aireon plans to introduce a comprehensive data set of global ADS-B equipped aircraft movements.  For the first time, one data set will be available of actual aircraft movements on a worldwide level. The Aireon data will provide accurate aircraft location and ADS-B message information to support global air traffic analysis, airspace and air route design, capacity and resources planning, predictability analysis for arrivals and departures and fleet optimization.

An accurate data set of global and regional air traffic promises to significantly enhance the analytical capabilities of the aviation industry.
