Rad-hard Smallsat / CubeSat Avionics Board, Phase I

Active Technology Project

Project Introduction

VORAGO will design a rad-hard Smallsat / CubeSat Avionics single board that has the necessary robustness needed for long duration missions in harsh mission environments. The board will exceed processing performance of 100 DMIPS and will include a rad-hard MCU and an FPGA to implement mission specific processing functions. I2C, CAN, SPI, and SpaceWire busses will be supported on-board along with four 8-10bit SERDES interfaces. On-board memory will include 16 MB of EDAC protected RAM, 4 GB of non-volatile memory storage and 256 kB of non-volatile memory for boot software. The board will accept and digitize 16 thermistor inputs and 8 active analog inputs. A watchdog timer and external reset signal will be provided on the board. The board will be no bigger than 90mm x 90mm and will be specified to consume no more than 3W. The deliverables for the project will include board schematics, bill of materials and costing, industry-standard deliverables for fabrication of the board, assembly and testing. In addition, a thorough component analysis will be reported including power consumption characteristics (to demonstrate that 3W will not be exceeded) and radiation performance specifications to ensure that the board has been designed to meet the objective of long duration missions in radiation environments. A board-level FMEA will be supplied as part of the deliverable and QML design practices will be followed and documented. In addition, a detailed list of software and hardware development tools for programming and developing command and data handling software will be supplied. Important software such as an RTOS will be supplied. More »
