British space comms tech heads into orbit | Computer Weekly
"Weighing around 150 kilograms each, the RF spacecraft carry the Azalea Enhanced Software Defined Radio - designed, developed, built and operated by BAE Systems. The equipment uses artificial intelligence (AI) to accurately process RF and SAR data onboard the satellites, turn it into actionable intelligence and transmit it securely back to Earth. The satellites will travel at approximately 7.6km per second, orbiting the Earth every 90 minutes."
"The developer notes that like a mobile phone operating system update, the payload can be rapidly reconfigured remotely while it's in orbit, ensuring Azalea remains at the cutting edge of space technology to deliver future customer missions. BAE Systems regards the launch as a crucial milestone in its self-funded Azalea mission, which will see the three satellites fly in formation at an altitude of 350 miles, using their ultra-wideband RF sensors to monitor and geolocate radio signals on Earth across vast distances."
Three BAE Systems Azalea radio frequency satellites launched into low-Earth orbit aboard Exolaunch on SpaceX's Transporter-15 rideshare mission on 28 November 2025. Communications with the UK-produced satellites were established across the first three contact opportunities between 23:05 and 04:55 GMT. An ICEYE Synthetic Aperture Radar satellite also joined the cluster, adding cloud-penetrating imaging capabilities. Each RF craft weighs around 150 kilograms and carries the Azalea Enhanced Software Defined Radio. The payload uses artificial intelligence to process RF and SAR data onboard, produce actionable intelligence, and transmit it securely to Earth. The payload can be reconfigured remotely while in orbit, and the three satellites will fly in formation at about 350 miles altitude to monitor and geolocate radio signals for defence, security, and civil use.
