Architecture and Design

The VOICE ATM system delivers trusted performance and proven reliability to ANSPs and aviation operators around the world. The system’s unique internet-protocol-based communications infrastructure allows for the centralization of operations through the reallocation of geographically disbursed resources—ideal for the management of airfields and remote towers.

Scalability, Flexibility and Future-proof

L3Harris has an extensive history of developing voice communications solutions for the international civil aviation community. Offering a complete end-to-end IP solution, VOICE ATM allows ANSPs to capitalize on their existing network infrastructure while providing the scalability and flexibility only found with a full IP-based voice communication system (VCS).
