Educational PocketQube Satellite
Veverka, Jiří ; Zamazal, Michal (referee) ; Povalač, Aleš (advisor)
Tato diplomová práce je zaměřena na návrh výukového satelitu typu PocketQube 2P (50x50x100mm) a pozemní stanice, které budou využívány ve výuce STEM laboratoří. Navržený systém byl navržen s důrazem na modularitu, snadnou výměnu za použití komerčních volně dostupných součástek a snadné pochopení subsystémů, které lze v družici tohoto typu nalézt, tedy palubní počítač, komunikační modul, napájecí systém a payload. Mimo vnitřních modulů byla vyvinuta i vnější konstrukce, která je celá vyrobena z desek plošných spojů a dohromady tvoří základ družice. Vyvinutá družice a pozemní stanice využívají ke komunikaci rádiový modul RFM98W s modulací LoRa.

Design and implementation of educational CubeSat
Košút, Martin ; Zamazal, Michal (referee) ; Povalač, Aleš (advisor)
This thesis describes the design of a CubeSat with a 1U (10x10x10 cm) size, which will be used in laboratory tasks. It includes mechanical construction printed on a 3D printer with six photovoltaic cells, mounted on the top. Cells will produce electricity to power all systems and to charge the onboard NiMH batteries to make the CubeSat independent of other sources of energy. The proposed design of an electrical power supply system and an onboard computer combined with a communication system is based on off the shelf components. The two-way wireless communication link between computer and a CubeSat is realized thanks to the ground station, which is also part of a design. Students will make other systems, which will communicate with the built in onboard computer via internal RS 485 communication bus. Internal EEPROM memory is used to save measured values. Modularity, possible future expandability, and easy repair in case of any failure were the key optimization parameters of the design.
