Ligado Focuses on Unmanned Sector in Push for Terrestrial Network
The Virginia firm that had been hoping to use satellite frequencies near the GPS band to support a terrestrial broadband network has changed its pitch to regulators. Ligado, previously named LightSquared, is working to convince the Federal Communications Commission (FCC) that its frequencies are the way to provide connectivity to the broad internet of things (IoT) including unmanned aircraft, driverless cars and other unmanned systems. ( more)

Satellite navigation signals from space are precariously weak and can easily be blocked, damaged, or compromised by a growing array of threats - including solar activity, man-made interference, malicious faking of GPS signals, and the manipulation of position and timing information. As we come to rely more and more on GNSS signals and data across a wide range of industries, understanding and mitigating against these threats will become a critical risk management activity for manufacturers, systems and applications providers, and end-users. 
 
BeiDou Driving Value of China's Satellite Navigation and Location Services Industry

The growing demand for precise location information, in combination with the ongoing evolution of GNSS technology, means that today's GNSS market is bigger than ever. In the recently released European GNSS Agency (GSA) 2017 GNSS Market Report -the fifth edition of the agency's popular report - it indicates the global GNSS market is expected to grow from 5.8 billion devices in use in 2017 to an estimated 8 billion by 2020. ( more)
