The first flight-ready incarnation of the SGR-05P-based receiver is referred to as the SGR-07, a stand-alone, packaged version of the SGR-05P providing robust power and communications interfaces. The SGR-07 communicates with the rest of the spacecraft exclusively over the dual-redundant CAN bus using the CANmodule-IIx. Testing of the SGR-07 has now been completed onboard SSTL’s UK-DMC-2 satellite, which is due for launch in early 2009.
“The CANmodule-IIx core with its standard AMBA APB system bus interface is designed for a smooth system integration. Although the target FPGA was for a satellite based application, it was impressive to see how quickly SSTL completed the core integration,”
SSTL GPS engineer, Reynolt De Vos Van Steenwijk, who worked on the UK-DMC-2, commented: "The integration of the core into our design went extremely well with excellent results and we found the team at Inicore responsive and supportive throughout."
UK-DMC-2 is a sophisticated new Earth observation satellite which will join other satellites already operating in the Disaster Monitoring Constellation (DMC), providing commercial remote sensing products and contributing image data to the International Charter: Space and Major Disasters.
The CANmodule-IIx core is ISO 11898-1 compliant and supports both CAN standard and extended frame formats. The FIFO based architecture features three hardware message filters, which enable back-to-back message reception with minimal CPU interaction. The message filters are enhanced to better support high-layer protocols such as DeviceNet. The system interface supports the industry standard AMBA APB bus, making it easy to integrate. Several synthesis configurations are available to obtain a gate-count optimized FPGA implementation.
