HELICOPTER HOMING BEACON "PRIVOD-3"
Non Directional Beacon "Privod-3" is designed for emitting radio signals with the purpose of helicopters homing.
- The NDB is designed for the installation on land-based and off-shore locations, including drilling platforms, ice-breakers and sea crafts, having helideck.
- Operating range of the NDB "Privod-3" is from 50 to 150 km and depends on antenna type usage.
- Monitoring system provides stable performance of NDB operation.
- Diagnostics system for easily maintenance and troubleshooting.
- Local control unit with touch screen with resolution of 320 x 240 pixels provides comfortable graphic user interface and NDB operating mode displaying.
- NDB units are connected via CAN bus. This industrial network technology provides stable system operation, permits easily unit hot swapping and connection of the optional units (for specific customer’s requirements).
- Units are installed in 19 inch cabinet to provide easily access for maintenance and hot swap.
- Distance between the antenna tuning unit (ATU) and the beacon cabinet up to 100 m.
- Matches to all antenna types of marine radio beacons.
