Move to Allow GNSS-Interfering Pseudolites Emerges in Europe

Two European proposals to allow pseudolites in the protected frequencies used by GPS and Galileo could soon be adopted, creating a potential interference risk to GNSS receivers and hampering efforts to protect satellite navigation spectrum, experts say.

Air Force Weighs Switching to Multiyear GPS Procurements

The Air Force says it might ask Congress for permission to implement bigger buys of GPS satellites beginning in fiscal year 2016 (FY16) once it sorts out whether to drop Lockheed Martin as the GPS III prime contractor and switch to a different manufacturer for the navigation payload.

The department told Congress in a recent report on multiyear procurement (MYP) that while its current approach “allows the government the flexibility to adapt to a changing budget profile and constellation needs, it prevents the program from realizing savings that MYP could provide.”

Europe Presses Ahead with Galileo Probe, Program

An independent inquiry commission chaired by Peter Dubock, began its work on August 28, 2014, its task: establish the circumstances of the so-called “major anomaly” that resulted in two Galileo satellites being placed into incorrect orbits last week.

The inquiry commission will identify root causes and associated aggravating factors, offering recommendations to correct the problem(s) and to allow for a safe return to flight for Soyuz launchers from the Guiana Space Center.

RTCA Standards Committee Grapples with UAS Collision Avoidance Rules

Techniques to avoid aircraft collisions took center stage as aviation experts met in Washington this week to continue hammering out the standards essential to integrating unmanned aircraft systems (UAS) into the nation’s skies.

The standards are being developed by RTCA Special Committee 228 (SC-228), one of the family of committees operating through RTCA, Inc., which develops consensus standard for aviation, which are then adopted and put into real-world practice by the Federal Aviation Administration (FAA).

Galileo Teams Investigating 'Injection Anomaly' of FOC Satellites

European Space Agency (ESA) and industry officials said today (August 23, 2014) that they are investigating Arianespace’s announcements about anomalies in the orbit injection of the Galileo full operational capability (FOC) satellites launched Friday.

“Complementary observations gathered after separation of the Galileo FOC M1 satellites on Soyuz Flight VS09 have highlighted a discrepancy between targeted and reached orbit,” according to a Friday statement by Arianespace, which leads the industry team handline the launch of the first Galileo FOCs.

Galileo Soyuz Launches May Be Frozen Following Launch Anomaly; Board of Inquiry, Internal EC Task Force to Study Situation

[Updated Ausut 26, 2014) Sources in Brussels say that the two Galileo satellites launched on Friday (August 22, 2014) will likely never reach their proper orbits, and the failure will mean new delays for the Galileo program, as Soyuz launches will be frozen until an investigation is performed and causes identified. Meanwhile, the European Commission (EC), European Space Agency (ESA), and launch contractor Arianespace will take part in a board of inquiry into the flawed launch.

GNSS Charts Drought-Driven Tectonic ‘Uplift’ in Western U.S.

Precise GNSS measurements have revealed that the severe drought gripping the western United States in recent years is changing the landscape well beyond localized effects of water restrictions and browning lawns, according to scientists at Scripps Institution of Oceanography at the University of California at San Diego.
