Reflected Blessings.
A technique developed by researchers at the University of Illinois at Urbana-Champaign distinguishes a reflected non-line-of-sight (NLOS) signal of a particular satellite from the LOS signal and characterizes the NLOS signal as coming from a virtual mirror-image satellite in the direction of the signal reflection point. By using information on the position and orientation of the reflector, the NLOS signal can be treated as an additional LOS signal. read more

Ubiqomm and Skyriver team on ‘Wi-Fi in the sky’ BVLOS drone flights

November 28, 2016By

Ubiqomm has unveils its ubiquitous high-speed data connectivity solution, especially designed for enterprise drone fleets engaged in present line of sight (LOS) and, in the future, beyond visual line of sight (BVLOS) flights. “The application for drones is increasing exponentially as companies apply drone technology for surveying and performing emergency operations in remote locations, and other use cases including traffic... read more
