Automatic Dependent Surveillance Broadcasting (ADS-B Out) is an aircraft ground and satellite-based transmission system. This system is apart of the Federal Aviation Administration’s (FAA) and European Aviation Safety Administration’s (EASA) newest iteration of their NextGen initiative. ADS-B Out is intended to increase the safety and efficiency of shared commercial airspace. This system makes aircraft visible in-real-time to Air Traffic Control (ATC) by updating with greater frequency and accuracy. The goal of mandating this system; as well as, the NextGen initiative is to create a safer, more efficient airspace by reducing ground holds and improving flight times. Ultimately creating a safer more enjoyable form of transportation for the millions of travelers flying every day.

Currently, Global is the owner of two Federal Aviation Administration (FAA) Approved Model List (AML) Supplemental Type Certificates (STC) ST04298CH and ST04299CH for the installation and activation of Automatic Dependent Surveillance Broadcasting (ADS-B Out). These STCs utilize Rockwell Collins TPR-901 Transponders and ACSS XS-950 Mode S Transponders. Global is confident that we are able to offer an ADS-B Out solution that is best suited for any customer’s needs.

Due to Global’s experience with this system and our close working relationship with the local Aircraft Certification Office (ACO), our team is able to provide quality ADS-B Out solutions while keeping budget, efficiency, and safety at the forefront of every program.
