Navigation Sensors and Systems in GNSS Degraded and Denied Environments
Abstract
Position, velocity, and timing (PVT) signals from the Global Positioning System (GPS) are used throughout the world but the availability and reliability of these signals in all environments has become a subject of concern for both military and civilian applications. International news reports about a successful spoofing attack on a civilian UAV at the White Sands Missile Range in New Mexico, USA have increased concerns over the planned use of UAVs in the national airspace and safety of flight in general. Other examples of the effects of GPS interference and jamming are illustrated in this presentation. This is a particularly difficult problem that requires new and innovative ideas to fill the PVT gap when the data are degraded or unavailable. One solution is to use inertial and/ or other sensors to bridge the gap in navigation information. This presentation summarizes recent advances in navigation sensor technology, including GPS, inertial, and other navigation aids. This presentation also describes recent advances in sensor integration technology and the synergistic benefits are explored. Expected technology improvements to system robustness are also described. Applications being made possible by this advanced performance include personal navigation systems, robotic navigation, and autonomous systems with unprecedented low-cost and accuracy.
