Inside GNSS • July/August 2013


Sometimes GNSS spoofing seems a bit like UFOs: much speculation, occasional alarms at suspected instances, but little real-world evidence of its existence.

As far back as 2001, a U.S. Department of Transportation Volpe Center report suggested that as GPS further penetrates into the civil infrastructure, “it becomes a tempting target that could be exploited by individuals, groups or countries”.

Location, Location, Location

In a part of the world where frustrated drivers will park anywhere, including squarely on a sidewalk, a local newspaper is using location data to shame car owners into shaping up.

The Village, a Russian online publication serving Moscow, St. Petersburg and Kiev; created a free app that notes a badly parked vehicle’s make, color, and license plate information when users snap its picture.

Phones, Drones and Privacy

Every breath you take . . .
Every move you make
Every step you take
I’ll be watching you

I originally planned on titling this column, “Waiting to Inhale,” recalling these lyrics and an editorial I wrote more than four years ago about my sense of relief at the departure of the second Bush administration.

I called that one, “Waiting to Exhale.”

FAA and Defense Department Work to Fix Civil GPS Funding

Federal officials are working to fill a funding shortfall nearly certain to occur next year given that both the House and Senate have cut an already halved budget request for GPS civil funding.

Sources confirm the Federal Aviation Administration (FAA) and the Department of Defense (DoD) are in talks about finding money to make up for the dramatic reduction. One source familiar with the situation said the FAA was searching its accounts for resources to address the loss.

GPS-Based Vehicle Crash-Prevention System Crafted to Protect Privacy

A new GPS-based technology designed to warn drivers in time to avoid collisions has anonymizing elements in its design to keep the location of vehicles private, according to the Department of Transportation (DoT).

DoT has focused a lot of effort on reducing motor vehicle accidents — a leading cause of death in the United States. Nearly 34,000 people died in collisions in 2010, the latest year for which data is available, according to the Centers for Disease Control. CDC estimates the lifetime costs of crash-related deaths and injuries in 2005 alone were $70 billion.

Adding Intelligence to Receivers

GNSS receivers and users, along with the critical infrastructures and services they support, face a growing threat from jamming, spoofing, and meaconing (JSM) events.

Several proposals for GNSS spoofing detection and signal authentication have been proposed over in recent years. These have focused mainly on adding cryptography elements to the GNSS signals and detecting RF characteristics of undesired signals.

Something Old, Something New

The past 15 years have witnessed tremendous developments of new and modernized satellite-based navigation (satnav) systems, including GNSSs, regional systems, and space-based augmentation systems (SBASs). These have been enabled by the original designs of GPS and GLONASS and, in turn, have stimulated the design of satnav signal structures with different characteristics from those pioneer systems.
