SIDEBAR: 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.

Two companies angling to provide the government with cutting-edge, GPS-based weather data may get a boost this fall if a bill aiming to improve forecasting wins U.S. House approval.
The companies, Bethesda, Md.-based Planet IQ and GeoOptics, Inc., of Pasadena, California, hope to use GPS radio occultation or GPS-OR to provide the National Oceanic and Atmospheric Administration (NOAA) and the Department of Defense with weather data.

During 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.
