Air Force, Congress Face Off over Space Program Management
The U.S. Air Force is in a tug of war with congressional lawmakers over how military space programs will be managed going forward. The House Armed Services Subcommittee (HASC) Chairman Mac Thornberry, R-Texas, this week threw his support behind a measure to move Space Command out from under the Air Force, placing it instead within U.S. Strategic Command (USSTRATCOM), one of the Department of Defense's (DoD) nine unified commands. ( more)

Satellite navigation signals from space are precariously weak and can easily be blocked, damaged, or compromised by a growing array of threats - including solar activity, man-made interference, malicious faking of GPS signals, and the manipulation of position and timing information. As we come to rely more and more on GNSS signals and data across a wide range of industries, understanding and mitigating against these threats will become a critical risk management activity for manufacturers, systems and applications providers, and end-users. 
 
Opposition to Ligado Plan Expands
Assertions by Virginia-based Ligado that its GPS interference issues were largely resolved were called into question by statements made by two key agencies and fresh opposition to a related spectrum request from nearly two dozen companies and associations. ( more )

New Reports on Performance Standards Confirm GPS's "Gold Standard" Status for PNT
The U.S. Air Force last week released two technical reports demonstrating that GPS continues to deliver exceptional performance to civilian users around the world. The 2014 and 2015 performance reports confirm that the GPS Standard Positioning Service (SPS) satisfied nearly all measurable performance commitments documented in the GPS SPS Performance Standard, furthering the status of GPS as the "Gold Standard" for positioning, navigation, and timing (PNT).  ( more )

Ellipse roll & pitch accuracy has improved by a factor of two (now 0.1° on all sensors), new accelerometers tolerate very high vibration environments (up to 8g), Galileo has been added to the Ellipse-N.   

UK Study Indicates Just How Costly a GNSS Disruption Can Be 
With so much of today's society reliant on GNSS technology, any extended disruption of service could cause quite an uproar. Several of these potential problems are described in great detail in a government report commissioned by Innovate UK along with the UK Space Agency and the Royal Institute of Navigation.  ( more )
