Today’s universities are the playground for new ideas and algorithms designed to solve the problems still present in satellite navigation. A prime example is the application of positioning in the so-called “urban canyon,” where the user is surrounded by skyscrapers and other high buildings to resemble the challenges of a big city. In this instance the actual broadcasted signal is hidden and only reflected versions of it arrive at the user position. Other projects can be imagined in the safety-of-life field. During fire rescue missions or other hazardous situations, satellite navigation can provide invaluable support.
To perform this kind of research a reliable signal source is mandatory. The GNSS simulator should allow users to redo special scenarios and add erroneous influence at anytime. Scalable multi-path simulation is also an essential requirement.
