The ADS-B Mandate: What You Need to Know

Airspace is becoming increasingly crowded. In a crowded airspace, position is critical, and ADS-B provides more accurate and consistent aircraft positioning, inexpensive traffic awareness service for other nearby aircraft and a more cost-effective solution for deployment than ground-based radar systems.

This is where ADS-B technology becomes an enabler for onboard surveillance technology to more accurately track aircraft anywhere in the world. The aircraft determines its own satellite-based position. This information (along with identification, category, velocity, status and other important data) is broadcast every second and can be received by air traffic control ground stations as a supplement to secondary radar or used by other aircraft to provide better situational awareness.

Automatic Dependent Surveillance-Broadcast (ADS-B) technology provides four distinct Services:

  • Automatic Dependent Surveillance-Broadcast (ADS-B)
  • Automatic Dependent Surveillance-Rebroadcast (ADS-R)
  • Traffic Information Service-Broadcast (TIS-B)
  • Flight Information Service-Broadcast (FIS-B)
