Iridium ASE-CIT-ADU Replacement ADU for Citadel Packages (ARA-AG3066900)

The Iridium ASE-CIT-ADU Replacement ADU (ARA-AG3066900) is a genuine all-in-one outdoor terminal designed for use within Iridium Citadel maritime security and safe room communication packages. This unit functions as the primary external communications interface, combining the Iridium satellite transceiver, GPS receiver, and antenna into a single ruggedised enclosure.

In Citadel installations, the ADU is typically mounted externally in a concealed or elevated location on a vessel — such as the funnel or superstructure — where it maintains a secure satellite link independent of the ship’s main communications systems. It converts Iridium satellite signals into voice and data, delivering connectivity to the protected Citadel safe room via a single composite cable.

Key Product Features

• All-in-One Outdoor Terminal: Integrates Iridium satellite transceiver, GPS receiver, and antenna in a single unit.
• Citadel System Compatible: Designed specifically for Iridium Citadel maritime security packages.
• Single-Cable Architecture: Uses a specialised Turret connector to carry power, voice (RJ-11), and data (RJ-45).
• Maritime-Grade Construction: Built for continuous operation in harsh marine environments.
• Secure External Deployment: Enables covert and resilient satellite connectivity for safe room communications.

What’s Included

• Iridium ASE-CIT-ADU outdoor terminal (MC05G)
• ASE-MNT20 vibration-dampening mounting bracket
• Breakout / adapter cable for internal Citadel system connection
