After 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.

Table 1Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Em. Univ.-Prof. Dr.-Ing. habil. Dr. h.c. Guenter W. Hein.
This is the first article in a series. For Part 2: Hybrid- and Non-GNSS Localization, see here.

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 maritime sector drives the global economy, with ships transporting more than 80% of world trade. Ships and ports have come to rely on global navigation satellite systems (GNSS) for a huge array of applications relating to position, velocity and precise universal and local time.

Federal watchdogs examining automakers’ privacy practices are urging a key regulatory agency to step up and clarify its role in protecting the location and other personal information of those operating connected vehicles. The report, posted on August 28, was just one of a number of location-privacy developments including advances in pro-privacy laws in some states and a pullback by Uber on its tracking of its customers.

The U.S. Air Force last week selected the senior civilian and mobilization assistant for the deputy chief of staff for Space Operations Directorate, or "AF/A11." Shawn Barnes will serve as the assistant deputy chief of staff for Space Operations, and Maj. Gen. Pamela Lincoln has been named as the Mobilization assistant to the deputy chief of staff for Space Operations.

After multiple reported incidents of jamming attacks, South Korea is working hard to develop an earth-based navigation technology as an alternative to GNSS to protect its ships from cyber-attacks.

The U. S. Air Force is weighing shortening the design life of the GPS satellites it buys after it finishes filling out the constellation with the final tranche of GPS III spacecraft.
Space Command reached out to the industry late last month asking for feedback on the ramifications of scaling back on the elements that make the GPS space vehicles (SVs) the “Energizer Bunnies” of space — the satellites that just go and go and go.
