摘要：AbstractThis work reports on a visual tool that has been developed to supplement theoretical lessons on Global Navigation Satellite Systems (GNSS) with real-world studies of current constellations. The tool was created using Matlab's Graphical User Interface Design Environment (GUIDE), and it is particularly intended for courses in aerospace engineering with GNSS content. As such, it highlights the space segment of these navigation systems and concepts such as visibility, groundtracks and coverage. Using this graphic tool, students can visualize the real position of all satellites in the GPS constellation at any time since its start of operation, analyze the number of satellites that can be visualized from any point in Earth, or study the quality of the navigational solution which depends on the relative geometry of the user and the satellites. The tool also allows to perform these studies for a flight between any two points on Earth, or for an user-defined region. A preliminary version of the tool was tried in a computer lab for a course in Aerial Navigation. Students reported some bugs but were mostly satisfied with the tool, as a survey shows.
