LTE cellular steers UAV: Signals of opportunity work in challenged environments

No GPS? No Problem! Long-term evolution (LTE) cellular signals can be exploited for accurate and resilient autonomous vehicle navigation in the absence of clear GNSS signals. Simulation and experimental results demonstrate that GPS-like performance can be achieved in the absence of GPS signals when cellular pseudoranges aid an inertial navigation system. By Zaher M. Kassas, Joshua J. Morales, Kimia Shamaei,... read more

Research: Assessment evaluates GNSS receivers’ tolerance of adjacent band

March 22, 2017By

By Stephen Mackey, Hadi Wassaf, Karen Van Dyke, Christopher Hegarty, Karl Shallberg, John Flake and Terence Johnson. The Adjacent Band Compatibility Assessment evaluated the adjacent radiofrequency band power levels that can be tolerated by GPS and GNSS receivers, to advance the U.S. Department of Transportation’s understanding of the extent to which such power levels impact devices used for transportation safety... read more
