Precision GPS Landing System Receives DoD Recognition

A U.S. Navy program that uses technology developed by a Raytheon-led team to land aircraft in harsh weather has been recognized with a Department of Defense (DoD) engineering award.

The Joint Precision Approach and Landing System (JPALS) Increment 1A ship system received the Systems Engineering Top 5 Programs Award for "successful implementation of systems engineering best practices resulting in program success," according to the DoD.

2012 European Satellite Navigation Competition Results

Finding your way indoors will be even easier with a new smartphone app from two Portuguese research institutes that augments GNSS with positioning using ultra-low magnetic field communication (ULF-MC).

Fraunhofer Portugal and the University of Porto’s Faculty of Engineering received the €20,000 Galileo Master’s prize for their innovation in this year’s European Satellite Navigation Competition (ESNC 2012) awards. The ULF-MC application was the overall winner from among 406 completed entries (the most ever) submitted from more than 40 countries.

GNSS Positioning and Precise Timing

As the forthcoming “Time and Navigation” opening next March at the Smithsonian National Air and Space Museum reminds us, modern navigation depends profoundly upon time — the more precise, accurate, and stable a navigation system’s timing is, the more precise, accurate, and stable its positioning capability.

LTE, Positioning, and the Implications for GNSS Over-the-Air Testing

Long Term Evolution (LTE) technology in mobile communications, often called 4G, is making its way into a host of consumer devices. It started with data-only modules for Internet connectivity but quickly made its mark on smartphones, automotive communication, and embedded modules that provide fast and reliable wireless data connectivity to the machine-to-machine (M2M) market.
