Spectra Group, together with industry partners Comtech, has demonstrated a high-capacity over-the-horizon communications system to the British Army.
Called COMET (Compact Over-the-horizon Mobile Expeditionary Terminal), it is a mobile tropospheric scatter (troposcatter) system providing low-latency data without the need to rely on satellites or multiple line-of-sight repeaters.
Troposcatter takes advantage of upper layers of the troposphere to send radio signals up to 300km, depending on terrain and climate conditions.
Simon Davies, CEO of Spectra Group explained to Shephard that, as COMET does not need a GPS, it can work even in denied spectrum environments. He added that the system also meets
