Signal Processing Controller for Link 22 (NILE)

The Link 22 SPC 1920 provides dual-channel functionality in a 1U x 19" rack mount enclosure for "NATO Improved Link 11" (NILE), designated Link 22 by NATO.
SPC 1 operates independent from SPC 2 without any restrictions. Each SPC is fully controlled by the NILE System Network Controller (SNC).

Three (of totally four) NILE defined communication modes are fully implemented. HF-EPM mode is ready for implementation but pending due to US regulations on TRANSEC availability. Proprietary AES-based TRANSEC solution - if potentially enabled by relaxed standardization - can be provided on demand but at the expense of lost interoperability.

For the HF fixed-frequency mode two suites of enhanced waveforms are available providing significant operational benefits. Increased transmission robustness enforces communication reliability for disadvantaged assets. The extended on-the-air runtime threshold enlarges the tactical beyond-line-of-sight communication range up to 1000+ NM. High-speed data rates offer increased network throughput needed in crowded mission areas or requested by new enhanced services.

Due to its great variety of adjustable interfaces the SPC 1920 can be easily adapted to existing on-board infrastructures.
