We can provide customer preferred solutions or where there is no indicated preference, we will scope the most cost-effective solution based on customer’s operational requirements. A range of configurations to provide resilience and redundancy are also available to suit the system application.

ATC Voice Recorder

Voice and Data Recorders

The normal requirement for a Mobile or Modular tower is Voice recording in accordance with ICAO standards in order to provide legal recording of communication between the ATCOs aircraft, other controllers and external agencies. This includes radio communications, telephone communication and in some instances ambient recording. Typically, this is done by monitoring the radios, the ATCO positions, the ground telco links, and if required a microphone providing ambient recording.

Although unusual in mobile solutions it is possible that ADS-B and/or Ground Surveillance monitors may be required, and this surveillance information can be recorded to provide evidence of the information displayed to the ATCO. Depending upon the system in use this can be Through The Wall (TTW) data taken from the specific system and/or At the Glass (AG) data obtained by “screen grab” devices.

There are many solutions available to our customers and as technology and regulations develop MATC can provide VoIP, analogue or hybrid solutions to suit customer needs from a range of 3rd party suppliers.

MATC are a responsive, flexible contractor. They enabled us to support the demands of our end user customer through program reviews, training, and product acceptance events.  At all stages we were kept informed on progress with regular project updates provided for the duration of the contract. MATC displayed excellent programme and risk management procedures throughout which kept this complex project on track.

The motive for purchasing the Mobile Air Traffic Control Tower was to provide all airports in Lithuania with a quick deployment back up ATC capability within SWIM enabled features by using common fibre links that have been installed at all Lithuanian international airports. Mobile ATC Systems were flexible so we (Oro Navigacija) were able to use in house facilities to integrate the MATC Cabin to meet our needs; this has worked very well for us.

Mobile ATC Systems Ltd helped us to carry out a complex shipment requirement from the manufacturer with a professional approach and good communications. Everything was done in a timely manner and there were no issues with the services we received. We would be happy to engage with Mobile ATC for future service needs.

MATC delivered three ORCs to UNICEF for outreach primary healthcare in Eritrea. Colin Chapman delivered end user training in Asmara to the Health Ministry and UNICEF personnel. Geoffrey Acaye, Chief of Child Survival and Development said “Thank you too for being so supportive in this phase of the project. We will certainly reach out to you for any further support whenever required. I am confident that this initial phase will stimulate the interest of the Government and donors to expand further”.

Why do I need a recorder?

Depending upon the role and purpose of the ATC tower, ICAO, ANSPs and regional aviation authorities require recording apparatus to be capable of recording and replaying messages or signals transmitted, received, or conveyed through the equipment at the ATC Unit or Aeronautical Radio Station. Basically, this means recording everything said and heard at an ATC Operators position, and what goes in and out of a radio. Where applicable radar data may also need to be recorded.

How Many Channels do I need?

This can be a complicated answer. Typically, even VoIP solutions are license based and one channel will be required for each signal source; that is ATC operator Positions, radios, telephone lines, and possibly ambient recording. In some cases, a small recorder of 8 channels will suffice but in others we have supplied 48 channels to cover the number of signal sources to be recorded.

How long do I have to keep the recording and how is it stored?

Typically, recordings needed to be stored for at least 30 days, and in the days of tape this was a significant effort. With most modern recorders everything is stored on Hard Drive and these are now large enough to store well in excess of 30 days before over-writing data. They can also have multiple simultaneous backups to assure data protection. Impounding and exporting recordings for investigation purposes is also now far simpler process.
