SIRIUS OBC LEON3FT DEVELOPMENT KIT
Smallsat Onboard Computer Development Kit
Designed for advanced satellite constellations in LEO and deep space exploration missions the readily available smallsat SIRIUS OBC LEON3FT DEVELOPMENT KIT delivers ‘always-on’ reliable operations that work every time on time with precision performance.
With enhanced error detection and correction, the Sirius onboard computer 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 Command and Data Handling System has a standard single string system that consists of an on-board computer (Sirius OBC) and a combined mass memory with CCSDC stack (Sirius TMC). The OBC runs mission specific software and manages the spacecraft system. The TMC receives and store payload data and platform housekeeping while at the same time distributing telecommands and serving mass memory data to the transceiver.
We offer various software design kits for this product, including BAL (Bright Ascension Ltd).
With 50 MHz LEON3F fault-tolerant soft processor, its RTEMS real-time operating system (RTOS) is compliant to IEEE 1754 SPARCv8. Utilizing SpaceWire on-board the main data bus, the on-board computer is designed to emphasis high performance, resilience and reliability.
The development kit includes a Sirius on-board computer with a RTEMS real-time operating system running on a FPGA based soft processor. This combination results in an outstanding on-board computer with high performance, resilience and reliability.
Easy-to-use interfaces, facilitating the development phase and reducing overall development and project costs. With the ability to unplug the OBC unit and test it on a flat sat environment the Sirius OBC kit is designed for desktop use with flight software environments.
