Aeronautics Capabilities Solutions Automatic Dependent Surveillance-Broadcast


Lockheed Martin is developing a solution that will support our C-130J operators in meeting the December 2019 deadline for Automatic Dependent Surveillance-Broadcast (ADS-B) compliant transponder equipage. This modification provides a way for C-130J customers to rapidly upgrade their aircraft with minimal downtime by pulling ahead equipment already planned for the Block 8.1 installation to provide an RTCA DO-260B Automatic Dependent Surveillance-Broadcast (ADS-B) Class B1 (ADS-B Out) compliant capability.

Lockheed Martin’s solution utilizes the Block 8.1 antenna locations and equipment. This modification will include dual APX-119/RT‑1861 transponders as well as dual GPS receivers that are Wide-Area Augmentation System compliant. This installation will fully meet all international requirements for ADS-B Out as well as meet the appropriate military Identification Friend or Foe (IFF) capabilities.

Since every operator has unique installation needs and military requirements, the Lockheed Martin ADS-B Out solution is available for a range of possible aircraft configurations. The ADS-B Out Solution can be economically installed by a Lockheed Martin C-130 Authorized Service Center.
