Jotron Ground to Air Radios, ATC Recording and Replay Systems

Jotron has specialised in products and systems for airspace and maritime communication for more than 40 years and has been a high quality supplier in the field of communications since its founding.

Jotron has operations in Norway, UK, US, Lithuania and Singapore, as well as an agent network covering the world.

Ground-to-air VHF and UHF radios

Serving the world of airspace communication for more than 30 years, Jotron offers a modern range of high performance VHF and UHF aeronautical band radios for both civil and military ATC purposes.

Designed to meet today’s requirement for voice communication, the radios are prepared for the future of digital data transmission. The unique modular architecture offers the most compact radio system configuration possible, while increasing reliability and simplifying installation, inspection and maintenance.

Well-established, with a significant reputation as a provider of modern air-traffic control systems, Jotron can create customer specific solutions, utilising accessories from top-end suppliers.

VHF AM multimode radio

Installed on every continent, our range of analogue VHF AM radios has earned a reputation for being among the most reliable radios available. References are available from civil aviation authorities that are employing these radios in the most severe environmental conditions.

Design and technology has not been compromised to create the most compact radio available, as shown by the fact that this is the radio range with the highest MTBF figures. The Jotron 7000 series VHF multimode digital radio combines excellent RF performance in congested areas with an advanced digital-signalling technique to cover the future radio communication needs of civilian authorities.

Totally controlled by an ultra-fast digital signal processor, the radio is the ultimate choice for all professional ground-to-air communication, with easy control, no internal tuneable parts and improved reliability. Easy to install and virtually maintenance free, this radio system complies with or exceeds all international standards.

UHF digital radio

New Jotron series 7000 UHF digital radios are designed to provide ground-to-air communication for professional users in the air defence frequency range. The radios provide excellent audio performance together with unmatched RF performance in tough electromagnetic environments. Voice over IP, AM and FM modulation, remote control via SNMP, and high MTBF are factors which makes these radios a crucial tool for the professional market.

UHF and VHF power amplifiers

Jotron has developed its own range of VHF and UHF power amplifiers. Using state-of-the art technology, the amplifiers are designed with internal gain loop, providing a very low distortion and excellent gain flatness over the whole operating frequency range, as well as a temperature controlled fan for lower noise figures and increased lifetime operation. Also containing internal bypass relays for main / standby and transceiver set-up, the amplifiers have an internal auto switch for back-up power in case of power failure.

Ricochet Solutions – Recording and Replay of all data

Ricochet was acquired by Jotron in 2012 and is part of Jotron’s ATC and Coastal Communication Division. Ricochet – a recording solution that in a single system captures – and synchronously replays – analogue/digital audio, VoIP, DVI and VGA screen images, composite CCTV, IP-Cameras, LAN radars, asynchronous and synchronous serial radars and other serial data, will assist investigatory work as well as search and rescue operations.

At the glass (ATG) and through the wall (TTW) screen recording

Ricochet’s screen recording software mirrors all operations, including mouse movements and information displayed for the controllers. It is available for replay immediately after recording and is optimized for fast recall. Combining the latest in high performance frame rate converter hardware with smart and efficient software it is possible to effectively record even the highest resolutions used in ATM – at the frame rates needed, without any loss of picture fidelity and without the need for extreme storage solutions. The recording is done ATG, which means that the images are recorded from the DVI cable. Screen recording does not replace radar recording, it complements it.

The technology is not vendor-specific and will interface to any system. The user may also keep the same way of recording screens even if the ATM system and CWPs are upgraded or replaced. During replay, the screen images are recreated in full synchronism with, for example, position voice communications. To make sure no data is lost; the screen image can be captured multiple times per second.

Capturing data TTW means tapping the data from the sensor, before processing and independent from what is presented to controllers. The Ricochet Radar Display is the fastest and easiest way to view primary and secondary radar data. The radar/track viewer is integrated in the Ricochet replay client tool where text based chart and chart object format are supported. The basic features of the area can be plotted and used as background. Tracks are plotted with target ID, featuring functions as range, zoom, pan, select reference and select target(s).

Multi-channel replay

With the Ricochet replay client the user is presented with extremely user friendly and quick access to the data. Multiple channels of various types can be selected with a few mouse clicks to practically instantly play audio, radar and screen images and other data, in perfect synchronization.
