Global satellite navigation: diverse systems and their technical functionalities

In the past, it was almost inconceivable to take a car trip to unknown places without a map or a road atlas. Since then, not only are such resources less and less often carried in the car, but a large majority of the population, in particular the youth segment, is no longer familiar with analog navigation solutions. Maps have been replaced by technical navigation systems, which allow for position determination and destination guidance through satellite signals and radio. In this article, we explain how satellite navigation works and compare different systems, which are currently available when it comes to navigation.
