Sirius TCM Development Kit

Sirius TCM Development Kit features easy-to-use interfaces, facilitating the development phase and reducing overall development and project costs. The development kit includes mass memory and telemetry/ telecommand functionality, with a focus on high reliability, resiliency and performance. The Sirius TCM is developed to support mission assurance requirements for a range of advanced nanosatellite and microsatellite missions, operating from low earth orbit to deep space. Fault tolerance is secured by triple-modular redundancy on FPGA and memory scrubbing.

Interface Management

The Sirius TCM main on-board data bus for high bandwidth data transfer uses SpaceWire technology. The transceiver interface is implemented according to the CCSDS encoding standards and used for satellite link services for compatibility with leading ground station networks. The Sirius TCM is supplied with user-friendly application software for the management of on-board services, facilitating out of the box integration, or alternatively can be supplied with a board support package for custom software development. The Sirius  TCM  Development  Kit offers dsub/microD connectors in the mechanical structure, which makes it easy to work with and simplifies the connector usage.

Modular Design

The   Sirius   products   are   designed   for   modularity.   A standard single string system consists of an on-board computer (Sirius OBC) and combined mass memory unit 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, as well as distributing telecommands and serving mass memory data to the transceiver. A Sirius data handling system is easily adapted for additional capacity and/or redundancy by adding or removing modules. This modularity extends to the Sirius TCM Development Kit and Sirius OBC Development Kit, allowing the kits to be stacked mechanically.

Flight heritage

We are very proud of our flight heritage since we flew our avionics on the first mission back in 2009. Many successful flights have followed since then and many new are scheduled.
