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.

Outlook for Civil GNSS Budget: Overcast with a Chance of Cuts

Though civilian GNSS activities fared reasonably well in the just-signed 2017 federal budget, the White House has already forecast cuts across non-defense agencies next year leaving the funding outlook for civil GNSS programs uncertain at best.

President Trump signed the fiscal year 2017 (FY17) spending bill on May 5, preventing another government shutdown and ensuring funding for agencies including the Department of Transportation (DoT), which is responsible for supporting civil GPS needs.

Officials at the Tsukuba Space Center of the Japan Aerospace Exploration Agency (JAXA) announced that the second satellite in the Japanese Quasi-Zenith Satellite System (QZSS) is scheduled for launch in June.

Designed to boost the accuracy and reception of the existing GPS system for Japan, a new version of a satellite that will orbit directly over the Japanese archipelago was unveiled last week. It will improve the existing GPS and provide a better positioning reading for the people in Japan.
