Space-Based ADS-B: Performance, Architecture and Market Options

In the last several years, Automatic Dependent Surveillance – Broadcast (ADS-B), has achieved significant traction with Air Navigation Service Providers (ANSPs) and the worldwide aviation community. Compared to ground-based radar, ADS-B offers greater accuracy and consistency, lower costs and shared situational awareness. Implementation of the FAA’s rule requiring aircraft to have operational ADS-B Out transmitter equipment by January 1, 2020 is now in the rearview mirror. Many other ANSP’s have or are implementing a similar requirement.
However, “traditional” ADS-B lacks coverage over oceans and remote areas. The satellite industry has responded to this capability gap and market need with a range of services that augment or replace ground-based ADS-B. This paper provides a market assessment of space-based ATS surveillance and aircraft tracking systems.
