State of Play in the European Union

Global navigation satellite systems have become core elements of the global economy. Essential for many civilian applications and innovations, GNSS brings rapidly growing economic benefits due to convergence of GNSS with smartphones, geospatial data, unmanned aerial vehicles, automated driving systems and other commercial technologies.

Webinar: Cutting-Edge Applications of Unmanned Systems

The incorporation of GNSS and inertial technologies is helping drive an explosion of systems development and applications of unmanned systems. On Tuesday, September 29, Inside GNSS and NovAtel will present a FREE 90-minute web seminar showcasing some of these applications, including the use of remote sensing technologies to assess pest populations in commercial crops and to conduct infrastructure inspections, with the aid of air and ground vehicles.

Register now for Tuesday, September 29, 2015: 9 am PDT

Let Us Now Praise

When China joined the GNSS club in 2007, it turned a satnav triumvirate into a quartet.

But some of the limelight needs to fall a little further from center stage — out there where the Indian Regional Navigation Satellite System (IRNSS) and Japan’s Quasi-Zenith Satellite System (QZSS) are not waiting idly in the wings.

Alternative PNT

At one time, GPS was expected to supplant a wide range of navigation technologies in the world’s positioning, navigation, and timing (PNT) portfolio. But an unexpected thing happened along the way.

GPS Confidential

Ubiquitous location-aware mobile devices, mainly GPS-enabled smartphones, have led to a boom in location-based services (LBS), which have been revolutionizing businesses and lifestyles. Common uses of LBSs include asset tracking, location-based advertising, emergency roadside service, turn-by-turn navigation, and real-time traffic & road information sharing.

Urban Localization and 3D Mapping Using GNSS Shadows

It is by now well known that GNSS-based localization in built-up urban environments can be extremely inaccurate. This is a fundamental problem that hardware enhancements cannot solve.

A GNSS receiver estimates 3D location and timing from pseudoranges from four or more satellites, assuming that these pseudoranges correspond to direct line-of-sight (LOS) paths from each satellite. In urban canyons, however, the signal from a satellite to the receiver suffers from multipath propagation and shadowing.
