Description
Space avionics systems are witnessing a change from highly centralized intelligence to distributed autonomous functions, thanks to the availability of high capacity FPGAs and microcontrollers that offload tasks alternatively concentrated in the on-board computer. The glue of this change are the command and control buses, and a similar process led in the late 80s to the development and successive adoption of CAN as an automotive and industrial automation bus.
The CAN workshop will include tutorials, exhibits together with presentations on CAN bus physical and protocol layers. With the arrival of the QML-V qualified radiation tolerant CAN bus transceivers, and the impending qualification of several CAN-able rad hard microcontrollers, the availability of larger and larger Rad-Tolerant FPGAs, space communications engineers are now able to implement a CAN bus network for spacecraft on-board communications and controls of the same level of complexity than a terrestrial CAN-based embedded system.
A CAN bus system will allow engineers to replace older, more complex wiring communications architectures, with a CAN two-wire bus network. Reducing the number of wires and weight along with lower power consumption and easier testability will result in major cost savings for spacecraft manufacturers. The planned modifications for of ECSS-E-ST-50-15C will be given, as well as an update on flying and about-to-fly CAN applications, in established space industry as well as in nanosats and academia. Additionally an overview of modern design tools and method commonly used by automotive industry in design, development, production and maintenance of CAN bus networks for safety critical applications will be discussed.

CANOpen IP Core EvolutionsThe CANopen IP Core (CCIPC) has been developed in the frame of the Exomars project. The CCIPC has been designed to implement the main aspect of the CANopen protocol in order to move from a SW to HW solution and to make all the CAN aspects, from Application to Physical layer, transparent to the final user. This presentation will provide an overview of the main architectural and functional changes made by SITAEL on the new CCIPC core and the future improvements that can lead CAN / CANopen as the main bus for the next space missions.Speaker: Mr Pietro Tosi (SITAEL)

Robust hot redundant CAN communication protocol for space applicationWith the accelerated development of remote terminal units, there is an increased need for a reliable interface protocol that can be used for communication over CAN. While the CANopen interface protocol is developed for automation and used in variety of terrestrial applications, the ECSS variant implements only a subset of its functionality. As such a CAN interface protocol suitable for use on spacecraft that includes all the beneficial features from the current ECSS CAN standard, but offers increased reliability by introducing software-based acknowledgments, was developed. Further, a hot redundant CAN bus for reliable communication was defined. Another key feature is the use of the extended CAN frame format as defined in the CAN 2.0 B standard. The application layer is, in contrast with CANopen IP, less demanding and therefore more suited for implementation on a microcontroller with less processing power.Speaker: Mr Lorenzo Gonzales (Skylabs)

Open source implementation of ECSS-CAN Bus Extension Protocol for CubeSatsWith the ever growing capabilities of FPGAs and microcontrollers, spacecraft systems are evolving from centralized architectures with a single main processing unit to decentralized layouts composed of multiple intelligent nodes. The backbone of this development is the command and control bus that interconnects these units. In this talk we present the details and results of a prototype implementation of the ECSS-CAN bus standard for CubeSat missions in C and Python. We demonstrate that the minimal implementation of this protocol stack can well be adapted to the tight constraints of small-sized microcontrollers.Speaker: Mr Artur Scholz (ESOC)
