Welcome back from your Labor Day Holiday Weekend! Here's some must read Inside GNSS content to help you get back into the swing of things.

Location Privacy: GAO Asks More of NHTSA, New State Laws In the Works
Federal watchdogs examining automakers' privacy practices are urging a key regulatory agency to step up and clarify its role in protecting the location and other personal information of those operating  connected vehicles. The report, posted on August 28, was just one of a number of location-privacy developments including advances in pro-privacy laws in some states and a pullback by Uber on its tracking of its customers. ( 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. 
Combined Spending Bill Unlikely to Impact GPS but Federal Shutdown Possible 
The old quip about limitations refers to cramming 10 pounds of stuff into a five-pound sack. Congressional lawmakers must be wishing for something that easy as they get ready to return to work Sept. 5.  ( 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.   
South Korea Developing an eLoran Network to Protect Ships from Cyber Attacks
After multiple reported incidents of jamming attacks, South Korea is working hard to develop an earth-based navigation technology as an alternative to GNSS to protect its ships from cyber-attacks. ( more )
These include the world's leading tactical grade 1°/hour turn-on to turn-on bias performance ring laser gyro-based HG1700 IMU and the rugged MEMS-based HG1930 IMU. The world's leading navigation grade HG9900 IMU offers extremely accurate bias performance of 0.003°/hour. Please contact our technical sales group at or +1.425.396.0829 for more information or technical assistance on Honeywell IMU's  

The U.S. Air Force last week selected the senior civilian and mobilization assistant for the deputy chief of staff for Space Operations Directorate, or "AF/A11." Shawn Barnes will serve as the assistant deputy chief of staff for Space Operations, and Maj. Gen. Pamela Lincoln has been named as the Mobilization assistant to the deputy chief of staff for Space Operations. ( more)

Enabling Collision Avoidance with Raw Measurements and Updated ADS-B Software 
Collision avoidance will be more practically and universally achievable, even in skies crowded with unmanned aerial vehicles (UAVs), if the aviation community takes advantage of the raw measurements already present in today's GPS receivers, but largely ignored in favor of using GPS position coordinates. Changes to existing aviation equipment could enable aircraft to estimate the flight paths of other aircraft far more accurately enabling safer operations even under impaired conditions. The use of the raw data, once integrated into standardized flight protocols, could dramatically help prevent midair accidents even if one or both of the aircraft is unmanned.  ( more )
