Internal Data Bus of a Small Student Satellite
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 satellites 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.
