Recording and Replay Systems for Air Traffic Control (ATC)

Ricochet is world-leading in synchronised recording and replay within Air Traffic Control (ATC) and marine markets. Ricochet was acquired by Jotron AS in 2012, and forms part of Jotron’s ATC and Coastal Communication Division. Ricochet’s recording solution captures, replays and analyses all data, ready to deliver the total scenario when reconstruction of an incident is imperative.

Ricochet has 400 recording systems installed world-wide, and their multi-flexible ATC solution offers superior performance in a simple configuration, with great emphasis on speed, reliability and simplicity. It safely records voice communication (audio), CCTV, radar, screen images and other ATC data. All sources are accessible through the same tool and replayed in perfect synchronization.

Company Profile


    AUDIO RECORDING & REPLAY SOLUTIONS FOR ATC – The Ricochet solution supports all different audio formats; analogue, digital and VoIP, without limitation of number of channels.  The solution supports numerous compression algorithms.

    RADAR RECORDING & REPLAY SOLUTIONS FOR ATC – When using Ricochet for radar recording and replay there are basically two methods of data acquisition, either from LAN or from Serial lines.

    For replay:

    • Feeding the replay out onto the same type of carrier and with the same format as it had when present in real-time, for presentation on the native radar display.
    • Using the Ricochet Movable Object Display, which is a radar/track viewer integrated with Ricochet Control Panel.

    The Ricochet Radar Display offers several alternative views.

    SCREEN RECORDING & REPLAY SOLUTIONS FOR ATC – The software helps you to record the screen to mirror all operations, including mouse movements, and information displayed to the controllers. This tool is optimized for fast recall, as well as for incident investigations. Both At The Glass, as displayed for the controller, and Through The Wall, the raw data information, are available. In APP and GMC environments, you can add recording and replay of metrological information, CCTV cameras and ambient microphones to give controllers best possible information before they make their decisions.


    For reproduction of the various data types, Ricochet replay software exists for audio, radar and CCTV. However, it is also possible to use the regular applications to reproduce recorded data, as Ricochet upon replay feeds the data back in the same form as it had when it was recorded. The Ricochet Recording and Replay solution supports recording and replay of all types of cameras; analogue, digital and CoIP.

    The Ricochet Replay Control Panel has been a significant contributor to the success of the Ricochet solution. Ricochet has taken the technology further, making all sources accessible through the same tool, replayed in perfect synchronization.

    The process of impounding data is automated and the relevant data are easy to select and extract for further analysis. The data can be copied to a suitable removable media and given to the investigators. The solution includes a tool to verify that the data has not been tampered with, as well as the new Impound Player, protected by a USB lock.


    The Ricochet solution offers easy export of a chosen audio and video channel/period to a single file. This file can be replayed by a simple Media Player and distributed through mail or sources like a CD or a USB.

  • Open Replay API

    The communication between the Replay Client and the Replay Server is defined by the Ricochet Replay API, a simple but effective TCP communication protocol that is fully documented and open to use for anyone.

    Users and user groups are easily administrated by Ricochet. Channel utilization statistics are logged and can be viewed graphically. Actions performed by users are logged, and by having access to the Audit Trail part of the administration tool the Audit Trail can be viewed. A comprehensive monitoring and alarm system is featured in the system.

    For training of controllers through simulation of real scenarios from a live system, Ricochet’s distributed recording and replaying solution is the perfect tool. Operated from ONE central position, Ricochet offers synchronous replay of data on several remote replay stations. Genuine recorded data and incident scenarios can be replayed and the instructor at the operating station is able to tailor made the content to each individual student. Debriefing can be done by using ATG screen recording and audio recording of the training.

    It is easier than ever to create and maintain a large, distributed system of Ricochet recording units due to the new generation Ricochet with an enhanced and improved modular architecture. By using the new replay server/manager and administration server/manager architecture, any number of autonomous recording units can be integrated via one access point, Ricochet client application provides system-wide access to replay and administration. The recorded channels from the different recorders are presented seamlessly to the user.
