Harbinger Sues U.S. Government over LightSquared

Harbinger Capital Partners, a hedge fund controlled by Phil Falcone that acted as the primary financial backer of LightSquared, is suing the United States government over the failure of the proposed terrestrial broadband wireless network that would have broadcast in RF spectrum adjacent to GNSS L1 frequencies.

Galileo IOV Satellite Failure Mystery Still Unsolved

[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.

FAA Seeks Comment on Groundbreaking UAS Application, Model Aircraft Rules

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.

GPS OCX Program Being Restructured as Budget Pressures Mount

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.

Supreme Court Decision Cites GPS Location as Factor in Warrantless Cell Phone Search

A unanimous U.S. Supreme Court decision issued last Wednesday (June 25, 2014) listed the history of precise locations contained in the phone as an example of the information that individuals have a right to have protected against “unreasonable searches and seizures.”
The decision, delivered by Chief Justice John Roberts, Jr., addressed two cases in which cell phones were seized in unrelated incidents and ruled that the contents of cell phones are generally covered by the Fourth Amendment.

FCC Courts GPS Community in Effort to Solve Spectrum Crunch

Federal Communications Commission (FCC) officials took a new tack last Friday (June 20, 2014) in their search for frequencies for mobile broadband, kicking off what they said they hoped would become an industry partnership that can find ways to get more out of the radio spectrum while protecting GPS.

GNSS Monitoring Stations Slide into U.S.-Russia Rift

GPS and GLONASS emerged from the depths of the Cold War to become the world’s leading dual-use (civil/military) GNSS programs in the post-Soviet era.

Now renewed tensions between their national sponsors, the United States and Russia, are undercutting a decade-long move toward GNSS cooperation.

The United States and Russia initiated bilateral GNSS cooperation in December 2004, with the primary goal of enabling civil interoperability at the user level between GPS and GLONASS. In June 2012 the two nations issued a renewed statement of cooperation in GNSS.

Russia Launches CDMA Payload on GLONASS-M

On Saturday (June 14, 2014) Russia placed a GLONASS-M satellite into orbit, carried there by a Soyuz 2-1b rocket from the Plesetsk Cosmodrome north of Moscow.

GLONASS-M 55 was put into the constellation’s slot 21 in the third orbital plane.

According to ISS Reshetnev, the manufacturer of the satellite, GLONASS-M 55 is equipped with an experimental payload capable of transmitting CDMA signals in the L3 frequency band, centered at 1202.025 MHz. Flight testing of the new equipment will evaluate the accuracy of the new CDMA signal.
