Rockwell Collins Successfully Demonstrates Long Distance Communication Links Using a Next-Gen High Frequency System

Rockwell Collins has successfully demonstrated the resilience of next-generation high frequency communications using a wideband high frequency system that works over a distance of 5,000 miles. The demonstration was carried under Rockwell’s contract with the Air Force Research Laboratory Information Directorate (AFRL/RI; contract FA8750-16-C-0269) and in support of AFRL/RI and Air Combat Command’s efforts to successfully communicate in satellite-denied environments.

Over the course of 30 days, Rockwell Collins’ next-generation high frequency (HF) network reliably and rapidly passed data files of various sizes up to 1 MB. The demonstration, which showed significant improvement over standard satellite and legacy HF systems, also tested ‘store and forward’ split site capabilities, which is a foundational element of next-generation HF networks.

Next-generation HF is a highly reliable solution for the transfer of data and secure, clear voice, which complements traditional SATCOM communications in denied environments. The technology leverages current HF system infrastructure to create an easily upgraded HF solution with performance previously not available.

The program will continue exploring the optimum network configuration and waveform technologies for this HF application. Leveraging next-generation HF technologies, like wideband high frequency systems, allows for HF networks to become a future force enhancer.
