Mobile ATC Systems Ltd (MATC) maintains a supplier agnostic position in order to provide solutions to suit all customer needs. 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.

Air-Ground Radio Communications

Air-Ground Radio Communications:

Air-Ground Radio Communications
VHF Radios. Aeronautical VHF Airband radios typically operate between 118.000 MHz and 137.000 MHz and provide most communications for ATC Air-Ground purposes. Extended frequencies are available from most manufacturers if required but a standard model is usually enough for most mobile tower applications. Radios are normally supplied with adjustable power settings ranging from, 1 Watt (W) or 5W to 50W without additional amplification. The power setting can usually be a low to medium level for Mobile VCR applications, and high-power settings would normally be used for en-route or longer-range applications.


UHF Radios. UHF Airband frequencies are normally used for Military Aircraft and operate between 225.000 MHz and 400.000 MHz. Most manufacturers have an Amplitude Modulation (AM) voice only model for clear voice operations, but many also offer radios with Frequency Modulation (FM) and additional Military waveforms to provide encryption or frequency hopping options. Some manufacturers also provide V/UHF radios capable of operating from 100-400MHz. These additional waveforms, frequency ranges, and the radios they are hosted on, are very often export controlled technology and require export licenses which will impact on their availability to certain parts of the world.

VHF and UHF Radio systems can be supplied as traditional analogue solutions or as EUROCAE compliant Voice-over-IP systems integrated into a local network with the VCS and Voice Recorder.

HF Radios. Typically operating between 1.6 MHz and 30MHz HF radios are commonly used for long range communication. For mobile tower applications we have found that low power models (typically up to 125 W PEP) are more than sufficient and a skywave range of between 550km and 630km could be achieved in ideal conditions. It should be noted that HF radio propogation is notoriously complex and effected by environmental conditions far more than VHF or UHF frequencies making it a less reliable communication medium.

Ground-Ground Radio Communications:

Airport Management Radios can also be provided for Ground-Ground airport management purposes and are available as VHF and UHF, AM or FM equipment depending on customer frequency requirements and licensing. We can supply fixed, mobile and handheld radios as well as radio repeaters if required.


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”.

How many radios do I need?

This depends on how you foresee the ATC tower being used. Typically, each controller will need 1 or 2 Ground to Air frequencies to carry out their role. They may be VHF, UHF or a mix. Occasionally an HF radio is required (which is usually hand mic operated from the console) and Ground to Ground radios may also be required. MATC has supplied a solution with as many as 12 channels (6 UHF and 6 VHF transceivers in a Main Standby Configuration) with an HF radio for shared use, but we have also seen requirements that simply need 2 radios for our smaller solutions. The best advice is to ask your ATC Controllers what their requirements are and discuss this with us to see what the impact is on the limited space available in the tower. We will do our best to accommodate any reasonable request.

What radios do you supply?

MATC remains agnostic in its supplier base and we can work with the major radio manufacturers. In the past we have delivered Jotron and Northrop Grumman Park Air Systems radios but do have access to General Dynamics and Rohde and Schwarz systems. HF radios are more complicated to install but we have found that the Barrett Radio solution suits the Mobile ATC Tower market better than most. Icom radios are also well suited for some shorter-range VHF and UHF Ground to Air and Ground to Ground needs but we can also supply Motorola if required.

What happens if a radio fails?

The power to the radios (at least the “main” radios) is usually supplied through by a UPS to prevent an overall radio system failure from a mains power outage but there are several options available to protect against a radio failure. Main and Standby radios can be installed with an antenna changeover device so that if one radio fails the other will take its place. The alternative to that is to supply a tuneable standby radio that can be manually tuned in case of a single radio failure. The latter is a cheaper option as not every radio requires a “standby” but a “main and Standby” radio assures that every frequency is protected.
