Copperchase Refit St AThan Tower with New ATC Systems

In April of 2019, on time and as planned, RAF ST Athan in the Vale of Glamorgan, Wales made the transition from a Military airfield to a civilian airport. The Transition Project was executed by the resident Air Traffic Service Provider, SERCO with the major ATC equipment and NAVAIDS supplied and installed by Copperchase.

Working to a tight timescale, Copperchase was able to assemble the right team and the right equipment for the SERCO transition works. Copperchase installed: –

MET System

  • Sensors – Wind Temperature, Pressure, Humidity, Visibility, Present Weather (Vaisala and Biral)


  • Certa / Affinity Dual 10KVA N+1 system with Bypass


  • MEP TCS9900 – 3 Operator positions, 3 VHF Channels, 2 UHF Channels, 8 Telephones, Alarms package.


  • VHF Park Air Sapphire T6TV
  • UHF Park Air Sapphire T6TU (Air UHF) Motorola SL5500 Repeaters, DM1400 Vehicle mobiles, DP1400 hand mobiles and DP4401EX Atex rated hand portables. (Ground UHF)


  • Copperchase Crash alarm system integrated with TCS9900 Voice switch


  • Cobham


  • Jotron Ricochet 24 audio (16 x ED137 & 8 Analog) I ATG screen recording & 1 TTW data recording.


  • Thinking Space Custom desk solution.


  • TRS Masts – 4 x 18m telescopic and fold over.


  • Wharton clocks – GPS head, time server with NTP output and desk displays


  • Copperchase AMHS ATC Messaging
  • Copperchase MET Data Displays and Vaisala Sensors, WID5xx Panel Displays
    • Wind, Temperature, Pressure
    • Cloud
    • Visibility and Present Weather.
  • Copperchase AUTO METAR
  • Copperchase ATIS
  • Copperchase Flight Data Management System (FDMS)

As with any project of this kind, the biggest task is to bring all the different elements together at the correct time while still maintaining the ATC service right up to point of changeover. As can be seen from the above list of equipment this was no mean task. Basically, every piece of existing (operational) equipment had to be replaced from the equipment room to the VCR.

The project started late 2018 and the deadline for changeover was 31st March 2019. A 4 day changeover period where the airfield would be closed, had been allowed for the transition period. Projects of this type are never problem free, problems started to occur in November 2018 when bad weather held up the civil works forcing some of the work due to be completed in December being pushed back to January and February while the deadline date remained the same.

Due to flexible and collaborative working between, Copperchase, Serco and the Welsh Government the project remained on track. The final 4 days had all three parties working together to strip out the old equipment including the heavily built steel MOD desk, repairing and making good the VCR floor, installing new carpets, installing new desk and fitting out with all the new equipment all in the space of just 4 days!
