Exercises outlines
The laboratory measurements will be focused on measurement of the basic radio function blocks and aeronautical transceivers, measurement of the navigation signals and receivers, especially satellites. The next part of the school term will be dealt with the algorithms of position determination in satellite navigation systems and their integration with the inertial sensors. Students will solve individual projects and present their results in small groups.
