The new High Integrity
Data Link (HIDL) is a robust digital data link designed by CDS
and Ultra Electronics for NATO's Maritime Unmanned Aerial Vehicle
program. The HIDL will assist operators in making safe UAV takeoffs
and landings on ships and also allow the transfer of sensor photos
and data to naval vessels and other surface terminals for operators
to study and disseminate.
It will enable a single surface
control station to simultaneously manage several air vehicles.
The link's waveform,
invented by CDS, provides remarkable "spectral versatility" to
avoid interference with radio traffic in the crowded RF spectrum.
HIDL also offers these characteristics:
- Uses any available RF channels, even if non-contiguous
- Networked for multiple simultaneous users
- Uses time and frequency diversity for resistance to jamming
- Low latency for safe control during launch and recovery
- Voice channel for communication with air traffic control
officers
- Relay function for over-the-horizon applications
- Variable data rate from 3 Kbps to 20 Mbps
- Back-up for Common Data Link
