Is your aircraft ADS-B Compliant?
Contact us for a Solution.


ADS-B Out (Automatic Dependant Surveillance – Broadcast) requires an aircraft to transmit its own GPS position via the Mode S transponder, regardless of whether the aircraft is being interrogated by a ground radar or by other aircraft’s TCAS. The GPS source must meet high accuracy and integrity requirements only available from a qualified WAAS GPS.

ADS-B is a fast approaching mandate. Using GPS technology, which is far more reliable than radar, ADS-B will allow air traffic control to safely reduce separation minimums.

By June 2020, business jets and turboprops will be required to transmit ADS-B to ground stations.

• ADS-B the future of air traffic control – changing the way the thechnology of the transponder works
• Designed to meet FAA requirements in 2020
• ADS-B In – coming in the future
