Echodyne, the manufacturer of innovative, high-performance radars for government and commercial markets, announces that it has received approval from the FCC for widespread deployment of its EchoGuard radar for radiolocation and radionavigation
in the United States, the company said.

Jihadi forum users also had awareness of successful 'spoofing' of a small, commercially purchased drone by a team at the University of Texas at Austin's Radionavigation
Laboratory, which was featured in U.S.
Humphreys and his team in the Radionavigation
Lab have built a low-cost system that reduces location errors from the size of a large car to the size of a nickel--a more than 100 times increase in accuracy.
This study focuses on compatibility assessment between the aeronautical radionavigation
service and the mobile service.

D'un cout de plus de trois milliards de dinars, ce projet, qui sera dote d'equipements de radionavigation
les plus modernes et de balisage de haute intensite, permettant respectivement le guidage des avions au vol, au decollage et a l'atterrissage nocturnes, doit repondre aux normes et recommandations de l'Organisation de l'aviation civile internationale (OACI) en matiere de surete, securite et qualite de service, a souligne le directeur des transports de Ghardaia.
The 3550-3650 MHz band is currently used by federal stations for Radiolocation Service and Aeronautical Radionavigation
Service (ground based), and by non-federal stations in the Fixed Satellite Service.
Les travaux ont porte egalement sur la construction d'une nouvelle tour de controle et l'acquisition d'equipements de radionavigation

Todd Humphreys, head of the school's Radionavigation
Lab, told a Congressional hearing it would be very difficult for an ordinary person to spoof a drone, although it might be within the capability of a terrorist or criminal network.
