This radio is designed for applications where ground-to-air communication is essential. Often used by ground services at airports, vehicle installations and for portable emergency purposes. This radio is also available in a compliant version with marine standard approvals, used at offshore installations and helidecks.
Record and replay for reconstruction and analyzes of critical air traffic situations
Ricochet is a world-leading recorder system developed specifically for the air traffic control and marine markets. This recorder can be fully integrated with any Jotron radio. By instant synchronous replay access and integrated replay, the operators can reproduce any scenario in the event an incident should occur. The system can identify the cause and ensure that improvements are implemented to avoid a similar incident in the future. The recording concept is modular and an unlimited number of channels can be recorded simultaneously. This recording solution assists investigatory work and is also of huge benefit to air traffic controllers, supervisors and management for training and quality improvement purposes. SmartOil is designed for small onshore and offshore ATC operations. It records up to 8 analogue audio channels, 22 digital audio channels via VoIP (ED-137) and 3 CCTV
