Global Navigation Satellite Systems Engineering, Policy, and Design
The seeming efficiency of having unmanned aircraft carry the same GNSS-based collision avoidance transmitters required for manned aircraft has generated a lot of interest as a possibly safe way to easily integrate unmanned aerial vehicles (UAVs) into the nation’s air traffic control system.

The Federal Communications Commission (FCC) is officially asking for feedback on a proposal by Ligado Networks to repurpose frequencies near the GPS band for a terrestrial broadband network. The long-delayed public notice and comment period is a step in the approval process, although there is no assurance that Ligado’s plan for a new wireless service — which may still cause interference to GPS receivers — will get the go-ahead.

The Air Force announced today (April 27, 2016) the award to Space Technologies Corporation (SpaceX) of an $82.7-million contract for GPS III Launch Services.
The Air Force characterized the contract as “the first competitively sourced National Security Space (NSS) launch services contract in more than a decade.” However, a decision last November by the United Launch Alliance (ULA), a joint venture of Boeing and Lockheed, not to compete for this GPS III launch effectively left SpaceX as the only bidder.

Kai Borre, now a professor and senior researcher at Russia’s Samara State Aerospace University, has released a new version of Easy Suite, a collection of Matlab-based scripts and explanatory text that illustrated a variety of common GPS issues.
The first Easy Suite files (easy1–easy10) were published in the periodical GPS Solutions in 2003. Those were augmented by a continuation (easy11–easy18) in Inside GNSS in the years 2009–2010.
The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) announced today (April 20, 2016) the successful demonstration of Enhanced Loran (eLoran) for precision timing of financial transactions at the New York Stock Exchange (NYSE).
The demonstration at the NYSE was hosted by Juniper Networks on April 19 and presented to technical representatives from the financial services, energy, and communication sectors.

The European Union (EU) has reached a deal with the British Ministry of Defense resolving a patent issue that could have limited the adoption of signals from the EU’s Galileo satellite navigation constellation.
"The European Commission [EC] has secured access to UK-owned patents related to Galileo signal in space technologies which will allow for their use by chipset and receiver manufacturers on a royalty free basis," according to a joint UL/EC statement supplied by a spokesperson for the UK’s Defense Science and Technology Laboratory.
