GNSS Stars in ITS World Congress

GNSS technology, which has been in the background of many intelligent transport system (ITS) projects and programs, will be front and center at the ITS World Congress 2015 next week (October 5-9, 2015) in Bordeaux, France.

Under the theme, “Towards Intelligent Mobility — Better Use of Space,” the event will draw thousands of registered attendees and around 200 exhibitors to take part in technical sessions, panel discussions, and demonstrations of ITS technology, products, and servuces.

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.

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.

Federal Cuts Expected in Civil GPS-Related Programs

In sharp contrast to the strong support given to the military’s satellite navigation programs in the next fiscal year, Congress is considering cutting every GPS-related programs supported by the Department of Transportation (DoT).
