New Spirent Test Framework Evaluates Threats to GPS, GNSS

September 14, 2015By

Spirent Communications has announced a Robust PNT Test Framework that evaluates GPS and GNSS security vulnerabilities for positioning, navigation and timing (PNT) systems. Threats to GNSS and related PNT applications are more orchestrated and coordinated, with the motivation to disrupt or cause financial loss. The technology to disrupt GPS has also become much more accessible, resulting in GPS vulnerability gaining attention... read more

Inexpensive Hack Spoofs GPS in Smartphones, Drones

August 10, 2015By

Researchers at Qihoo 360, a Chinese Internet security firm, say they have found a way to make a GPS emulator that can falsify the location of smartphones and in-car navigation systems, reports Forbes. The system is inexpensive compared to expensive, sophisticated GPS emulators that can cost thousands of dollars. Qihoo’s researchers hacked a Tesla Model S in 2014, taking control of the... read more

The current WINS form factor (left) sits beside a prototype for the future incarnation.

A new device is being developed to enable foot soldiers to find their exact location in GPS-denied situations. If satellite signals are blocked by heavy jungle canopy, or because of enemy interference, soldiers — and Headquarters — will still know where they are with the Warfighter Integrated Navigation System (WINS). read more

All GNSS Attend, But Galileo Gets the Spotlight

March 30, 2015By

First and foremost, let’s give a big hand to Adam and Anastasia, the two Galileo FOC satellites that were successfully launched on March 27. Following the not-so-successful Galileo launch in August, it was imperative that this go smoothly. Although the Double-A launch occurred after the conclusion of this year’s Munich Satellite Navigation Summit, anticipation of the event set the context... read more

Bill Supports eLoran as GPS Backup

March 27, 2015By

A bi-partisan group of legislators led by Congressman John Garamendi (D-Calif.) has introduced a bill that would require the U.S. Secretary of Defense to establish a backup for GPS within three years using eLoran. The National Positioning, Navigation, and Timing Resilience and Security Act of 2015, H.R. 1678, was co-sponsored by Congressmen Duncan Hunter (R-Calif.), Peter DeFazio (D-Ore.), and Frank LoBiondo (R-N.J). Garamendi is the... read more

GNSS Lies, GNSS Truth

November 6, 2014By

A new method detects spoofing attacks that are resistant to standard RAIM technique and can sense an attack in a fraction of a second without external aiding. The signal-in-space properties used to detect spoofing are the relationships of the signal arrival directions to the vector that points from one antenna to the other. A real-time implementation succeeded against live-signal spoofing attacks aboard a superyacht cruising in international waters. read more

Danger, Will Robinson! Beware the IMES of Japan

October 8, 2014By

In May 2011, Dinesh Manandhar and Hideyuki Torimoto of GNSS Technologies, Inc., Japan, penned a very interesting article in GPS World titled – Opening Up Indoors: Japan’s Indoor Messaging System, IMES. The opening paragraph of their lengthy article seemingly describes the Holy Grail for the indoor positioning lobby: “An indoor messaging system (IMES) has been developed to meet the challenges of indoor... read more
