Global Navigation Satellite Systems Engineering, Policy, and Design
The European Space Agency (ESA) released dramatic illustrations today (September 16, 2014) of the orbital locations of the two errant Galileo spacecraft launched on August 22, the intended orbit, and the locations of four In-Orbit Validation (IOV) satellites.

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.

GPS Networking, headquartered in Pueblo West, Colorado, has announced that it now offers electro-magnetic interference (EMI) shielding on its GPS/GNSS Splitters.
Interference between electronic components is an increasing issue as more wireless components are used to complete broadband systems. Reducing disturbance among separate frequencies through EMI shielding is a critical deliverable for project managers, says Eileen O’Halloran, general manager at GPS Networking

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.”

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.
