ADSBbased

ADSBbased refers to systems, applications, and processes that rely on Automatic Dependent Surveillance-Broadcast data for surveillance, tracking, and related services. It encompasses hardware networks that receive ADS-B signals, software platforms that ingest and process the data, and data pipelines that disseminate it to users and applications.

ADS-B is a surveillance method in which an aircraft determines its own position using GNSS and broadcasts that position along with identification, altitude, velocity, and other data. The broadcasts occur on 1090 MHz Extended Squitter (ADS-B 1090ES) or, in some regions like the United States, on 978 MHz UAT. Ground stations and airborne receivers capture these messages and convert them into track data that can be used for monitoring and analysis.

Data in ADS-Bbased systems typically include aircraft identification, unique ICAO address, airborne position, altitude, speed, and heading. This information can be aggregated from multiple receivers, corrected for transmission gaps, and made available to air traffic management, flight tracking services, research, and hobbyist platforms.

Applications of ADSBbased technology include real-time traffic information for air navigation, flight-tracking websites, automated alerts, flight-pattern research, and situational awareness for operators and airport authorities. It also serves as a supplement to traditional radar, improving coverage in remote areas and enhancing data availability for safety and operational planning.

Limitations include dependence on transmitted ADS-B data quality and coverage, as not all aircraft broadcast ADS-B, and potential privacy considerations for operators. Regulatory frameworks and standards, such as those defined for ADS-B by ICAO and RTCA DO-260, guide interoperability and deployment across regions.
