Global Navigation Satellite Systems Engineering, Policy, and Design
Despite the continued decline in sales of portable navigation devices (PNDs) and the alternative solutions from smartphones, smart watches and eyewear, the portable GPS-enabled device market is anticipated to continue to hold its own thanks to dedicated heads up display/eyewear, cycling, and health/tracking devices, according to a market research company.

GSS8000At a time when more and more services rely on GNSS for timing, navigation, or location comes the burgeoning realisation that unencrypted, civilian GNSS is vulnerable to accidental interference or malicious meddling.
That the hoaxing of GPS receivers is a reality and not a distant science-fiction threat has been underlined in a typically 21st century way, by disclosures on social media such as youtube.

First I thought to title these comments, “Learn from the People,” but readers might have confused me with Chairman Mao. (I spent some time recently around the Yangtze River, although I didn’t take the opportunity to swim in it as the Great Helmsman did.)
In any case, my thoughts turned toward the masses and the mass market as a result of working with the authors of an article in this issue on cooperative authentication. They have extended a chain of innovative proposals drawing on the crowdsourcing concept of data sharing among nearby GNSS users or “peers.”

Music right around the corner
This will be the 26th international technical meeting of the Satellite Division of the Institute of Navigation. It is the world’s largest and oldest GNSS conference, founded in 1987 as the ION GPS conference.
Significant progress has been made in integrating two classes of small, unmanned aircraft into the national air space (NAS), an area of considerable interest for GNSS companies whose products provide navigation and guidance for many of the unmanned systems.
Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.
The 2014 European Navigation Conference and exhibition will be held at the World Trade Centre (WTC) in downtown Rotterdam, Netherlands on April 15, 16 and 17, 2014. It will focus on positioning navigation and timing (PNT) technology, innovation and business applications. The technical sessions will cover all aspects of PNT developments and applications.
The deadline for abstracts is December 31, 2013
Online registration is open. Early bird registration ends February 15, 2014.

Ismael ColominaSIDEBAR: Ismael Colomina’s Compass Points
Ismael Colomina began his career in 1982. “So, in a way,” he says, “I grew up as a professional at the same time GPS was growing up and maturing. GNSS has always been present in my working life; so, I never experienced the ‘GNSS, aha!’ moment. Rather, I never stopped thinking ‘GNSS, of course!’"

Establishing someone’s immediate whereabouts is emerging as a key element in preventing credit fraud and improving cyber security.
The technique uses location data, derived from GPS and other sources, to estimate the likelihood that the person making a request to enter a building, access a computer network, or use a credit card is actually who they say they are.

EquationsDuring the past two decades, the Global Positioning System, together with other GNSSes, has become an essential element of the global information infrastructure, with myriad applications in almost every facets of modern businesses and lifestyles, including communication, energy distribution, finance and insurance, and transportation. Ever-growing dependence on GNSS creates strong incentives to attack civil GNSS, for either an illegitimate advantage or a terrorism purpose.

Averna Technologies has announced the availability of RF Studio for National Instruments Software Defined Radio Platform (USRP), converting the USRP into a portable RF system for the recording and playback of real-world GNSS signals.
IFEN GmbH, in partnership with WORK Microwave, have announced the release of software update v1.9 for their NavX-NCS GNSS multi-frequency simulator product line.
A key enhancement to the NavX-NCS solution is comprehensive support of China’s BeiDou-2 navigation satellite system, according to the companies. By enabling real-time simulation of second-generation BeiDou satellite signals, NavX-NCS expands a user’s GNSS signal capability beyond GPS, Galileo, GLONASS, and satellite-based augmentation system (SBAS) constellations.
