U.S. military efforts to field jam-resistant GPS weaponry not only run behind schedule, they continue to fall back, according to the annual report from the Department of Defense (DoD) Director, Operational Test and Evaluation (DOT&E) Nickolas Guertin. Because “the lack of M-code capable receivers limits the M-code use by U.S. and allied warfighters,” branches of the Armed Forces are now sourcing directly from commercial suppliers.

Scientists at Draper Laboratory have patented a celestial navigation system called a sliced-lens star tracker, which in its early form can achieve 50-meter accuracy in GNSS-denied environments. Improvements are expected as the technology evolves. Vehicles of all kinds may be able to benefit when using this system for navigating by the stars.

Arianespace recently announced it will launch a total of eight new Galileo satellites over the next few years.
The European Union Agency for the Space Programme (EUSPA) selected Arianespace to launch four new Galileo satellites for Europe’s satellite navigation system, according to a news release. This comes after the European Space Agency’s (ESA) order to launch four satellites last October and will complete the deployment of first-generation Galileo satellites.
