Surveillance Networks

En Route Airport/Airfield Radars

The first ATC Surveillance Radars in the UK, connected cross site by optical fibres, was by FTI in 1984 for the CAA at Stornoway, Isle of Lewis. Replacing BT's leased landlines, project pay back period was 5 years.

FTI has Networked (IP & Legacy Non-IP) the following types of ATC Air Traffic Control Surveillance Radars:

ADS-B Auto Dependent Surveillance-Broadcast

MLAT Multilateration

PAR Precision Approach Radar

PSR Primary Surveillance Radar

SMR Surface Movement Radar

SSR Secondary Surveillance Radar

Radar Flight Displays

Networked to Control Towers over leased Telecom lines and optical Fibre cables.

FTI is providing a migration path from legacy Analogue to IP, following the withdrawal of Analogue Services by Telecom Providers.
