Video Transmitter, Receiver and Data Link

Multi-protocol wireless transmitter or transceiver available in frequencies from UHF to Ku (FAA certification DO-160 and FCC authorization)

Troll’s LinkBox is a revolutionary data link capable of providing downlink and optional uplink of multiple IP streams and control data. Its built-in multi-port Ethernet switch and optional wireless router allow seamless connection to cameras, mapping systems, tracking antennas and other sensors.  Radio options are flexible and configured for each customer’s application.

Available in standard 1/2 ATR (Air Transport Rack) units it features a built-in touch screen monitor that provides operators with the ability to configure and control the aircraft’s entire data link system. The LinkBox is easily controlled from third-party mapping systems. This greatly reduces the complexity in the cockpit placing all systems controls in one place (no additional control heads required).

Video, Audio and Data options

The LinkBox can support any video input including multiple video streams. The LinkBox also supports both internal encoding and streams from an external source over IP. The transmitted video can be displayed on the local display or optional external HDMI monitor. Audio is supported in both analog and embedded modes. Data may be sent over serial or via built-in Ethernet links. Bidirectional data options are available to support full network bridging and routing.

Unidirectional and Bidirectional Air-to-Ground Communications

Troll’s LinkBox can be configured with any number of radio options including unidirectional DVB-T, bidirectional DVB-T and TDMA based data link technology. The LinkBox is not dependent on any one transmission standard and can easily be adapted to customer specific technologies. Our systems experts will work with you to find the perfect configuration for your needs.

Troll’s Link Box distills the entire system into a 1/2 ATR controller that simplifies the operation and management of:

  • Internal or external microwave radios
  • Modulation, error correction, bandwidth
  • Encoding, decoding and encryption
  • Antenna monitoring, switching and control
  • Power monitoring and distribution
  • Video control and monitoring
  • Audio control and monitoring
  • Multi-port Ethernet switching and optional wireless routing
  • PC application for local or remote control of full system
  • Interfaces with both Aero and Churchill mapping systems (complete system control)
