Q: How do you use GNSS to compute the attitude of an object?
By Inside GNSSAfter several years of shifting plans the competition to build the next tranche of GPS III satellites is poised to start, though the context in which that contest will take place has changed markedly from when planning first began.

Carlo Bagnoli, STMicroelectronicsMultinational semiconductor and telecommunications company Qualcomm is a world leader in the design and marketing of 3G, 4G and next-generation wireless technologies. Headquartered in San Diego, California, Qualcomm has been widening its footprint in the Europe, Middle East and Africa (EMEA) region, with a core focus in Europe.
“We expect to grow Qualcomm’s presence in Europe, becoming a major EU (European Union) player in the digitization of European industries,” said Qualcomm senior vice president and president of Qualcomm Europe, Enrico Salvatori.

EquationsGNSS is the technology of choice in most applications due to its dedicated infrastructure, Earth coverage, medium to high accuracy, and large market penetration. Most of the applications, including those we download on our smartphones, are in the category of Location Based Services (LBS). However, there are many other services and businesses that rely heavily on GNSS performance and reliability. For instance, Intelligent Transportation Systems (ITS) make extensive use of GNSS technology and this dependence will only grow in the future.

Figures 1 – 8, Tables 1 & 2, Equation 3The vulnerability of GNSS to various forms of malicious interference have been widely discussed in recent years, and have considered a wide range of both real and potential attacks. Some of these have included extensive studies of commercially available jamming devices, while others have considered the more comprehensive case of spoofing, where the interference takes the form of genuine GNSS signals (For details, see papers listed in Additional Resources, including M. G. Amin et alia).

The Next Generation Air Transportation System (NextGen) is setting no records in government efficiency or speed. So, it’s time for the Federal Aviation Administration (FAA), Congress, and partner agencies to change the verb tense and transform NextGen into an operational ThisGen.
