The most important thing we build is trust


Weighing just 10kg and consisting of only two boxes plus the antenna, AVIATOR 300D provides SwiftBroadband Safety Services, voice and IP data connectivity for your flight deck.

Cobham’s AVIATOR 300D SwiftBroadband SATCOM solution combines FANS 1/A safety services and voice connectivity with IP Data capability.


AVIATOR 300D’s built-in ACARS Aero gateway AAGW facilitates messaging over Inmarsat’s SwiftBroadband network, providing for cost effective operations. The solution architecture is simple to install with a 2 MCU SBU and “flat pack” HLD and Intermediate Gain Antenna with a combined weight under 9.9 Kgs/22 Lbs. The system’s Intermediate Gain Phased Array Antenna (IGA) is the smallest in its class.

AVIATOR 300D offers significant size, cost and weight savings over legacy satcom solutions and is an ideal replacement for large Aero H/H+ terminals. The system’s built-in wired and wireless Ethernet connectivity for the cockpit IP network allows for easy interfacing with external devices, such as EFBs, iPads or AIDs during all phases of flight. AVIATOR 300D is participating in the FAA PARC CWG SwiftBroadband Safety Service Evaluation program and offers a bridge to the next generation of multichannel SwiftBroadband terminals, which will have full aircraft domain segregation using Inmarsat’s SwiftBroadband Safety Services.
