Airborne Signal Processing Controller SPC 1921

The SPC 1921 provides DSP single-channel functionality in an ARINC-600 2 MCU standard chassis for "NATO Improved Link 11" (NILE), designated Link 22 by NATO.

The SPC 1921 is the airborne version of the SPC 1920, generated by porting full functionality to the 2 MCU standard form factor (comparable to ARINC-404 1/4 ATR short).

 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.
