Module D: Satellite and Navigation Systems

Introduction in satellite and navigation systems. Development of satellite systems through history. Fundamentals of celestial mechanics, useful satellite orbits and their properties, transport of the satellite into orbit and trajectory adjustments. Space environment, managing the location and temperature of satellite, power sources on board the satellite. Properties of radio links Earth-satellite, satellite-satellite and satellite-Earth, Doppler shift in satellite communications.

Design of satellite telecommunications equipment for point-to-point links, broadcasting, mobile telephony, satellite telecommand and telemetry. Development of navigation systems through history. Ground navigation: Maritime (LORAN) Aeronautical (VOR, DME, ILS), positioning systems based on mobile telephony. Satellite radionavigation: Doppler systems Transit and Cikada, 3-D systems GPS, GLONASS and GALILEO. Primary and secondary radar, pulse and FM radars, Doppler radars. Remote sensing, passive radiometry, active radar with synthetic aperture.

The purpose of this course is to provide principles and techniques of satellite radio links and basic of navigation systems. Understanding the basic laws of space technology, the possibilities and limitations of communication links with the space orbiter. Understanding the basics of ground and satellite radionavigation, radiolocation, and remote sensing.

Lectures, where students are introduced by the theoretical basics and laboratory courses, where some of the problems are solved practically.
