Link 22 Airborne Signal Processing Controller SPC 1921.
The SPC 1921 is the airborne version of the shipboard SPC 1920, built by porting the proven SPC 1920 functionality to airborne suitable hardware. The standard SPC 1921 incorporates one functional Signal Processing Controller (SPC) entity, providing single-channel operation for Link 22.
HF-EPM mode of operation is ready for implementation but pending due to US regulation on TRANSEC availability. A proprietary TRANSEC solution – enabled by relaxed standardization – can be provided on demand but at the expense of violated interoperability.
