Cobham Airborne TETRA

Cobham has delivered airborne TETRA radio systems across the world. Cobham has the experience and understanding to deliver equipment and support to meet airborne customers’ needs.

Why Airborne TETRA? TETRA (Terrestrial Trunked Radio) is the World’s preferred

Government communications infrastructure. TETRA, a cellular,

trunked communications system, is similar in architecture to

commercial cell-phone systems. Many governments are implementing

single, countrywide, TETRA infrastructures as their new digital

communication system for their key agencies. These include Police,

Ambulance Military, Fire and other government users.

TETRA delivers: Secure, reliable trunked and direct-mode

communications, interoperability between agencies and the ability to

send both voice and data. Interoperability is facilitated by the ability

to make point-to-point calls between all users on the Network and

through Talkgroups.

The TETRA infrastructure consists of: Fixed base-stations,

Switching and Management Infrastructure (SwMI) and the mobile

radios (Terminals).

The UK is a World-leader in the implementation of TETRA and

pioneered the implementation of TETRA for airborne use. Cobham’s

involvement with this work since the beginning means that we are

the most experienced provider of avionics-standard airborne

TETRA systems.

Cobham has supplied avionics standard airborne TETRA systems for a

wide-range of Government users, in the UK and Internationally.

TETRA in the Airborne Environment • The TETRA Standard includes specific elements

for airborne use. There are a number of additional

features which must be considered, including:

– Highly Preferred Subscriber Class (HPSC)

– HPSC ensures that the airborne radio

terminal affiliates to ground base

stations specifically designated for use

with aircraft

– Cobham’s airborne TETRA range is HPSC tested

and proven

SINGLE RADIO SYSTEM

DUAL RADIO SYSTEM

CH250 dual TETRA radio controller.Works with optional RH150 remote CDU.

7-450-14 SERIES TRANSCEIVER Works with CH150 or CH250 CDU

7-450-3 TETRA TRANSCEIVERFor use with CH450/RH450

TETRA Security – Encryption • TEAs (TETRA Encryption Algorithms) are

used to encrypt transmissions between all

radio terminals and base stations

– TEAs are geographically-based.

For example, TEA2 is used in the

Schengen Region

– Cobham’s core TETRA radio covers all

four TEAs

• End to End (E2E) encryption encrypts the

complete link between the two ends of the

communication path

Commissioning and Support of Airborne TETRA • Cobham offers a full range of support tools

and services. These include:

– Programming tools

– Support for installation

– Assistance with commissioning on the

network, including loading air interface

algorithms and radio customisation

– Focused SLAs

– Software upgrades

– Obsolescence
