GPS Innovation Alliance Applauds Reintroduction of Moving FIRST Act

The GPS Innovation Alliance (GPSIA) issued the following statement on reintroduction of the Moving FIRST Act by Senators Catherine Cortez Masto (D-NV), Richard Burr (R-NC), Cory Gardner (R-CO) and Kyrsten Sinema (D-AZ), as well as Representative Mark DeSaulnier (D-CA). By establishing the Strengthening Mobility and Revolutionizing Transportation (SMART) Challenge Grant Program, this legislation will encourage the use of technology, including the Global Positioning System (GPS), to advance innovation across communities nationwide.

GPS III: The Next Big Step in GPS Modernization

[Editor’s Note: This article was written and submitted by Mark Crews and John Betz.]

With the launch of the first next-generation GPS III satellite, GPS III Space Vehicle 01 (GPS III SV01), on December 23, 2018, the Global Positioning System (GPS) took a major step in modernizing technology and capability. The U.S. Air Force has continually improved GPS since the launch of the first GPS Block I satellite in 1978, and this ongoing modernization has provided new signals, greater accuracy, and increased robustness for civil and military users. After the first 10 GPS III satellites are launched over the next few years, up to 22 GPS III Follow-on (GPS IIIF) satellites will provide yet another step increase in GPS capabilities.

GMV Uses GPS and Galileo to Provide Robust Timing for the Financial Sector

An increasing number of applications require accurate, reliable, and traceable signals for time and synchronization. Key fields of application include banking and finance, telecom networks and electricity grids. GMV’s WANTime is a new time service for the city of Madrid, Spain, distributed using the White-Rabbit network protocol over optical fiber. A pilot customer of the service is currently the Madrid Stock Exchange (Bolsa de Madrid), connected to GMV’s datacenter by a network link of around 50 kilometers.

GNSS Cybersecurity Threats: An International Law Perspective

 

Hostile cyber operations such as jamming and spoofing of GNSS signals are a growing concern. While they do not cause major damages to the satellite navigation system as such, they can have severe effects on critical national infrastructures and many other systems. Here, we address how international telecommunications law as well as the international law on the prevention of war apply in this context.

New Chimera Signal Enhancement Could Spoof-Proof GPS Receivers

New Chimera Signal Enhancement Could Spoof-Proof GPS Receivers

 

Improvements to GPS performance are often incremental, achieved by squeezing better performance out of existing systems with clever tweaks, smarter analysis and sharper receivers. Then again, every once in a while, there’s a huge leap in the capabilities of the system itself—an advance so big that it makes you appreciate all over again the elegant wizardry of satellite navigation.
