Global Navigation Satellite Systems Engineering, Policy, and Design
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.”

Q: What is the effect of user and CORS height on NRTK performance?
Dr. Inder Gupta, The Ohio State UniversityChris Bartone, Ohio UniversityWith new signals and frequencies coming on line with modernized GNSSs, antennas play a more crucial role than ever in receiver system design.
Antennas are often an overlooked or undervalued aspect of GNSS user equipment.

The eighth International Satellite Navigation Forum will take place during the Navitech exhibition at the Expocentre Fairgrounds in Moscow, Russia on April 23 and 24, 2014.
Informing the national and international audience about GLONASS innovations is the main goal of this forum.
The Navitech Expo (Navigation Systems Technologies and Services) runs from April 23 to 25. It is Russia’s major exhibition and congress devoted to satellite navigation.
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!’"

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.
