AAC Clyde Space are Europe’s leading supplier of Command and Data Handling (C&DH) solutions for satellite missions. Our precision solutions support an ever-expanding range of applications, from cutting-edge science to earth observation and the Internet of Things. Designing satellites and space missions is complicated. There are all sorts of things to consider, like how much data will you process, the computing performance needed for your mission, do you need GPS or have large mass memory requirements. Choosing the right solutions for your satellites can be a complex and time-consuming exercise. But AAC Clyde Space can make it a lot easier to choose the right C&DH solutions. Customers can leverage many tens of thousands of engineering hours in development and continuous improvements as an off the shelf solution.

Designed for advanced nano-satellite constellations in LEO and deep space exploration missions the readily available Sirius OBC with LEON3FT delivers ‘always-on’ reliable operations that work every time on time with precision performance. With enhanced error detection and correction, the Sirius OBC is tolerant to Single-Event-Effects (SEE) in logic and data storage. Fault tolerance is secured through TMR (Triple-Modular Redundancy) on all FPGA flip-flops and through boot flash and EDAC (error detection and correction) on memories. The development kit is powered through a mains 12V adaptor, eliminating the need for specialised power supplies or other laboratory equipment.

Sirius spacecraft avionics are modular in design. Modules can be combined to offer redundant configurations, or to simply accommodate mission specific requirements. The Sirius TCM LEON3FT has a standard single string system that consists of an on-board computer (Sirius OBC) and a combined mass memory with CCSDS stack (Sirius TCM). The OBC runs mission specific software and manage the spacecraft system. The TCM receives and stores payload data and platform housekeeping data while at the same time distributing telecommands and serving mass memory data to the transceiver.

Flight proven across multiple mission applications for a range of customer requirements, this readily available solution has a reputation for reliability and performance for advanced small and nano-satellite missions. The Sirius TCM LEON3FT has inherited advanced error detection and correction in it’s design. The real-time operating system runs on a LEON3FT fault-tolerant soft processor, compliant to IEEE 1754 SPARC v8, and fault tolerance is secured by using triple-modular redundancy on FPGA and memory scrubbing.
