Abstract [en]

This thesis presents a platform for a small student satellite. A backplane solution with slots for 8 individual modules is proposed. The backplane provides the modules with power and a common data bus, as well as mechanisms for isolating modules from the rest of the system and a possibility of restoring misbehaving modules. It has a power consumption of about 100mW. An on-board controller has been designed and tested. It consists of a 32-bit MCU, a NAND flash memory for housekeeping logs, an SRAM memory for processing variables, an OTP memory for safe storage of module firmwares, USB interface and a wireless intra-satellite communication module. The on-board controller has the main responsibility for monitoring and preserving the satellite’s health. The power consumption will be dependent of the final firmware, but a rough estimate is about 100mW. Also, an experimental wireless intra-satellite communication system is proposed. The system consists of a small wireless module, that will be integrated onto any module that is a part of the wireless network.
