GNSS User Technology: State of the Art and Future Trends

The advances on miniaturization, computation capabilities, and cost reduction of semiconductor technology have placed Global Navigation Satellite Systems (GNSSs) as the favorite choice for positioning. Nowadays, positioning is a key factor in many essential tasks of our modern society, and will even become more important due to the advent of new concepts such as the Internet of Things (IoT), smart cities or autonomous driving. The extensive use of GNSS in a wide-range of applications has caused a migration from the professional segment to the mass-market segment, both technological and in terms of performance. This poses new and more stringent requirements in terms of accuracy, robustness, ubiquity, and continuity, for the “open sky” GNSS design. Hence, GNSS technology has experienced an unprecedented evolution in the last decade, and it is expected to exponentially evolve in the next one. All this evolution is considered in this paper with the aim of providing a unified reference for current GNSS receiver technologies and solutions, and its expected evolution in the next years (e.g. up to year 2030). We consider receiver concepts, antenna, front-end, digital signal processing, and positioning algorithms. The impact on the different GNSS market segments and applications is also analyzed.
