The ability to accurately obtain position, speed, and time is important in a variety of applications including transport, communication, and security. Global Navigation Satellite Systems (GNSS) – such as Global Positioning System (GPS) – are largely used in these applications, although connection to satellites can be vulnerable to disruptions. For these reasons, the development of the next generation of position, navigation, and timing (PNT) systems has widely attracted attention from researchers in the scientific community, driven also by latest advances in a number of technologies including atomic clocks and LiDAR systems.
This Collection Position, navigation, and timing features original research articles on position, navigation, and timing, looking at new technologies for the next generation of such systems.
