Network RTK and Reference Station Configuration

Q: What effect does network size have on NRTK positioning?

A: Network real-time kinematic (NRTK) positioning is nowadays a very common practice, not only in academia but also in the professional world. In the last 10 years, several networks of continuous operating reference stations (CORSs) were created to support users. These networks offer real-time services for NRTK positioning, providing centimeter-level positioning accuracy with an average distance of 25–35 kilometers between the reference stations.

Staying In Lane

Staying In Lane

Next-generation car navigation may well require the ability to identify the lane in which a vehicle is operating on a motorway. This could support advanced driver assistance in general as well as the observation and study of driver behavior and traffic flow. Such road vehicle applications call for sub-meter positioning accuracy, often in real-time — all this preferably at low-cost.

A San Francisco Bay Area company — Making Virtual Solid–California (MVSC), which snared a trio of awards in a global GNSS competition for its novel approach to driver assistance, is still in early phases of development.

The origins of the company, however, go back more than 40 years to the Cold War era when its principals, Chris Grabowski and Tom Zamojdo, were studying physics and theoretical mathematics at the University of Warsaw, Poland.

But more about that later — first, the news.

FCC Moves Against Online Retailers of GPS Jammers

A discontinued model of GPS Jammer offered through UK website.

Increasing incidences of interference to GNSS signals has led to a crackdown on Internet-based companies offering devices to jam cell phone, Wi-Fi, and GPS signals.

In October, the Federal Communications Commission (FCC) Enforcement Bureau issued 21 enforcement actions against online retailers in 12 states for illegally marketing more than 215 different models of wireless communications jammers, including nearly 80 types of devices that could jam GPS signals.
