While the GNSS community waits for the scheduled launch on Friday (August 1, 2014) of the seventh GPS Block IIF satellite, the United Launch Alliance successfully lifted a three-satellite Air Force Space Command (AFSPC) payload into geosynchronous orbit on Monday (July 28, 2014) from Cape Canaveral Air Force Station, Florida.

The European GNSS Agency (GSA) announced today (July 29, 2014) that a recent 10-day test has successfully tracked and demodulated data from encrypted signals of the Commercial Service (CS) from available Galileo satellites.
Using receivers located in Tres Cantos, Spain, and Poing, Germany, the Early Proof of Concept (EPOC) team tracked encrypted Galileo E6-B and E6-C signals. Non-encrypted E6-B and E6-C signals have previously been tracked.

Two powerful lawmakers are weighing rewriting the rules for the way frequencies are allocated as part of an overhaul of the nation’s telecommunications laws. The effort, which is likely to see legislation drafted next year, is considering options such as flexible licensing and receiver standards that could directly affect the GPS community.

[Updated June 16, 2014] Sources in Brussels say the recently reported “power loss” that threatens to end the brief transmission life of Galileo GSAT0104, the fourth Galileo in-orbit validation (IOV) satellite, has nothing to do with the onboard atomic clocks, but could have been caused by a failure in the components linked to the solid-state power amplifier (SSPA), including the output multiplexer, cables and/or antenna.

Federal aviation officials appear to be moving quickly to defuse mounting pressure for the commercial use of unmanned aircraft, clarifying their authority over such aircraft and starting the public process for licensing small firms for limited operations.
The Federal Aviation Administration (FAA) has taken a tough stance in its interpretation of the legal uses for model aircraft published on June 23 in the Federal Register. The issue surged into the national spotlight when the agency failed to win a legal challenge over its authority to regulate such devices.

In response to the ongoing federal budget squeeze, the U.S. Air Force is restructuring the contract for developing its new GPS ground system, a move that could further delay its completion.
The Air Force has asked Raytheon, its contractor for the Next-Generation Operational Control System (OCX), to develop an alternative plan in light of fiscal limitations.
“The current baseline approach is unaffordable” given the funding constraints and “appears to be a much higher risk,” said Steve Moran, the director of GPS Mission Solutions at Raytheon.
