Nanosatellite Design and Electronics
FEKT-MPA-NDEAcad. year: 2022/2023
Students will become familiar with CubeSat and PocketQube format satellites, their mechanical structure and in detail with individual electronic systems - OBC computer, ADCS position control, COM radio communication, EPS power supply system. They will learn to design systems with regard to functional safety, incl. relevant pre-start tests. They will get acquainted with the specifics of communication with small satellites, the concept of a terrestrial command station and telemetry decoding. The end of the course and laboratory exercises are devoted to the practical implementation of nanosatellites.
Learning outcomes of the course unit
- explain the basic principles of electromagnetic wave propagation in free space and in the atmosphere
- use a logarithmic expression of ratios and power levels
- quantify the energy balance of a radio link
- evaluate the basic types of satellite orbits and characterize their parameters
The subject knowledge on the Bachelor's degree level is requested.
