Rockwell Collins has successfully demonstrated the resilience of next-generation high frequency (HF) communications using a wideband high frequency (WBHF) system over a 5,000 mile distance, the company announced on 18 September.
The demonstration was conducted under a contract with the Air Force Research Laboratory Information Directorate in support of efforts to successfully communicate in satellite-denied environments.
Over the course of 30 days, Rockwell Collins’ next-generation HF network reliably and rapidly passed data files of various sizes up to one megabyte. The demonstration also tested 'store and forward' split site capabilities, which is a foundational element of next-generation HF networks.
According to the company, the demonstration showed significant improvement over standard satellite and legacy HF systems.
Next-generation HF is being developed as 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 programme will now continue exploring the optimum network configuration and waveform technologies for this HF application.
The airborne three-domain, the two ground-based and the ¼ ATR OpenVPX-based cross-domain systems were engineered to provide real-time security across multi-domain operations.
DARPA’s Mission-Integrated Network Control (MINC) programme was set up to develop an autonomous tactical network and enable critical data flow in contested environments.
Why space is an essential part of modern military capabilities
Defence-secure mixed reality headsets can save hours, or even weeks, of travel time to fix defunct equipment or get subject experts effectively “on-site” where they are needed.
The Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) counter-improvised explosive device (C-IED) and Drone Restricted Access Using Known Electromagnetic Warfare (DRAKE) counter-UAS (CUAS) systems are mounted and dismounted RF jammers.
Adarga’s Vantage information analysis tool is in service with the UK MoD and individual UK forces. It builds on the company’s Knowledge Platform which processes, organises and analyses open source material, as well as information held by the user’s military, security and intelligence services.
