Reliable Onboard Computer for CubeSat-class Picosatellite, 2013
Original language description
The breadboard model of the onboard computer subsystem was developed to validate the concepts of reliability improvement strategies of electronic systems exposed to ionizing radiation, in this case, in the project of a small student satellite ?CzechTechSat?. Microcomputer subsystem is based on two identical cores (C8051F120 microcontroller) for its high computational performance (up to 100 MIPS) and motivated by the positive flight heritage during "QBX 1" and "2 QBX" CubeSats space campaigns. Subsystemsize and layout corresponds to the industrial PC/104 + format containing doubled serial interface with differentiators (to reconstruct the data carrier signal from heavilly impedance loaded buses onboard satellite, six analog inputs for signals from temperature sensors, interface for onboard color camera with current consumption measurement. Subsystem integrates electronic circuits for the processing of the diagnostic software (Housekeeping) with intelligent power management. Increasing
