Course detail

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

The graduate is able to: (a) describe the nanosatellite structure of the CubeSat and PocketQube formats; (b) describe the basic electronic systems of a nanosatellite; (c) evaluate functional safety and necessary tests; (d) define the requirements for the design of a selected nanosatellite subsystem and its integration.

Prerequisites

Attendant should be able to:
- 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.
