BAE Systems is set to launch its first multi-sensor satellite cluster into low Earth orbit in 2024 to deliver high-quality information and intelligence in real time from space to military customers. Known as AzaleaTM, the group of satellites will use a range of sensors to collect visual, radar and radio frequency (RF) data, which will be analysed by on board machine learning on edge processors to deliver the resulting intelligence securely, anywhere in the world while still in orbit. Following the acquisition of In-Space Missions last year, BAE Systems is one of a small number of British companies with the capability to design, build, launch and operate satellites.

The expertise brought by In-Space Missions complements the Company's existing advanced technologies and will become an integral part of its multi-domain capability. AzaleaTM will also boost the UK's ability to understand the threats and hazards in, from and through space. The AzaleaTM cluster will deliver timely, actionable intelligence, essential for military operations and disaster response.

Comprising four highly resilient satellites which, together, are capable of gathering, analysing and communicating Synthetic Aperture Radar (SAR), optical and RF signals. Unlike conventional, single-purpose satellites, the cluster can be fully reconfigured whilst in orbit in the same way a smartphone installs a new app; this ensures it can deliver future customer missions and expands the lifecycle of the satellites. The programme supports the UK Government's Defence Space Strategy, published earlier this year, which named Earth observation as a priority area to help protect and defend UK interests, a sovereign capability which AzaleaTM could provide.

BAE Systems is working with Finnish firm, ICEYE, to combine its own expertise in sensor technology with ICEYE's advanced SAR technology to be included in the cluster. SAR provides high-resolution imagery of the Earth's surface, day or night and in any weather conditions. This persistent monitoring makes it easier to detect instant physical changes, such as the movement of hostile ships or aircraft or the location of people at risk during natural disasters, such as floods and forest fires.

Existing space-based sensors require multiple terabytes of data to be transferred to Earth before being processed and distributed. The traditional transfer process can take many hours and is reliant on intermittent RF links and the availability of suitable ground stations. The AzaleaTM system saves valuable time by combining and analysing data in space.

It will be able to identify activities of interest and directly communicate with users on the ground within moments of detection – securely delivering assured data, in a useful timeframe, directly to the hands of decision makers.
