State of Play in China

The BeiDou Navigation Satellite System (BDS) is China’s contribution to the world in the domain of Global Satellite Navigation System (GNSS). The BDS is being developed by the Chinese government, mainly through military departments, with key considerations for China’s national security, economic interests and social progress.

Is it possible to build a low-cost system to detect and locate a single GNSS jammer in near-real time?

Q: Is it possible to build a low-cost system to detect and locate a single GNSS jammer in near-real time?

A: GNSS jammers are an ongoing threat to the reliable use of GNSS. The problem of geolocating GNSS jammers can be addressed using a time-difference-of-arrival (TDOA) processing technique; however, this problem is quite different than geolocating jammers in other radio frequency systems. The two main differences are:

(1) No GNSS are available to use as a timing reference.

ESA Puts Brave Face on Galileo Clock Failures

At the traditional January media briefing in Paris yesterday (January 18, 2017), European Space Agency (ESA) General Director Jan Woerner was forthright in laying out the knowns and unknowns about the failed rubidium and hydrogen maser clocks onboard orbiting Galileo satellites, clocks that are absolutely crucial for accurate positioning.

Defense Authorization Bill Signals Full GPS Funding, Pushes GPS Back-Up

Yesterday (December 23, 2016) President Obama signed the National Defense Authorization Act (NDAA) for Fiscal Year 2017, a $619-billion bill with a number of provisions affecting satellite navigation.

The legislation (S. 2943) fully authorizes the administration's requests for all the elements of the GPS program — and signals indirectly that appropriators eventually will provide comparable support — although the NDAA does put additional requirements on those developing the new GPS ground system.
