Anotace:

The subject acquaints students with the basics of physics of the space environment and the technologies used in space systems, satellites, spacecrafts and launchers and methods used for the design and preparation of space missions. Subject matter includes a detailed description of the instrumentation of satellites and spacecrafts and its resistance to external influences of the space environment, and analysis of instruments and systems for spacecratfts and methods of their testing. It provides a basic overview of the trajectories of spacecrafts and their applications. The course also covers optoelectronics in space systems, sensors used, their modeling and description. It discusses the principles of underlying calculations, simulations and their processing.

Požadavky:

Physics at bachelor level, basics of Matlab and C/C++

Osnova cvičení:

Laboratory exercises in the first half of the semester will focus on practical verification of basic principles of space instrumentation, systems and subsystems and methods of design of space missions. In the second half groups of 2-3 students will be created, which in turn will solve the problems from the fields of teaching materials. The students will work together with teachers, so that at the end of the semester they will be able to present solutions in the form of a short presentation (10 min.). There will also be organized excursions.
