Positioning with 5G next-generation cellular technology, based on higher bandwidths and frequencies, promises to open up new possibilities for localization services. As GNSS receivers share their position awareness across more powerful cellular networks, smart traffic management, asset tracking and personalized drone-based delivery will be just three examples of expanded capability. A European Space Agency (ESA)-sponsored test recently simulated this broadening PNT potential.
