AsteRx4 OEM receiverSeptentrio has launched its next-generation dual-antenna GNSS receiver — the AsteRx4 OEM, a multi-frequency receiver that incorporates the latest GNSS tracking and positioning algorithms and operates with all available GNSS signals (GPS, GLONASS, BeiDou, Galileo).

NovAtel Inc. has announced the launch of the Relay RTK radio module, a docking station that provides radio connectivity for the company’s SMART6-L L-band–capable GNSS receiver.
The European GNSS Agency (GSA) unveiled its latest GNSS Market Report today (March 25, 2015) at the Munich Satellite Navigation Summit in Germany.
The fourth and most comprehensive in a series of GSA studies, the 80-page report describes current and projected GNSS receiver sales by volume and value and highlights market opportunities, technology trends, and future developments of GNSS.

NovAtel graphicNovAtel Inc. has announced significant performance improvements to its PPP positioning solution.
Thalwil, Switzerland–based u-blox reported revenue and profit growth in its most recent annual report, driven by strong sales in its GNSS and wireless chipset and module business.
Consolidated revenue was CHF270 million (US$276.7 million) in 2014, a growth of nearly 23 percent compared to 2013 while net profit increased by 39.6 percent to CHF34.4 million (US$35.2 million), representing a 12.7 percent net profit margin for the year.
Dr. John Fulton, Ohio State UniversityNowhere has the fact that GNSS can guide things besides military weapons and transport manifested itself more profoundly than in agriculture.
While Google and automotive manufacturers struggle to figure out how to put autonomous vehicles on the highway, farmers have been using GNSS for well over a decade to guide equipment through their fields — along with a host of other ag-related, site-specific applications.
Indeed, GNSS — along with an array of other high-tech resources — is transforming agriculture at an accelerating rate.

Equations 1 – 11Q: How does a GNSS receiver estimate velocity?
A: Stand-alone single-frequency GNSS receivers represent the largest slice of the commercial positioning market. Such receivers operate mainly in single point position (SPP) mode and estimate velocity either by differencing two consecutive positions (i.e., approximating the derivative of user position) or by using Doppler measurements related to user-satellite motion.

Chris Blackford of Sky-Futures speaking at AUVSI’s Unmanned Systems Europe 2015. Peter Gutierrez photoJust as you do when you get in your car, the UAS, UAV, drone, RPAS and even ROAV communities — who probably need to agree on an acronym — are beginning to take GNSS for granted. But presenters at the AUVSI Unmanned Systems Europe 2015 conference held Tuesday and Wednesday (March 3–4, 2015) in Brussels had little to say on the subject, to our great disappointment, even though virtually all of the vehicle/vessel systems under discussion use it and need it.

New rules recently adopted by the Federal Communications Commission (FCC) to help emergency responders better locate wireless 911 callers highlight the role of GPS and GNSS technologies while boosting the use of alternative positioning technologies in indoor locations.
However, the new enhanced (11 (E911) rules, adopted January 29 and published on February 4, explicitly avoided a decision on the use of GNSS systems other than GPS.

Ray Clore, U.S. State Department. Peter Gutierrez photoAlmost half of the sessions at the International Navigation Conference (INC) 2015 held this week (February 24–26) in Manchester, England, were devoted to the theme of GNSS resilience and vulnerability, a topic that Dana Goward of the Resilient Navigation and Timing Foundation has been trying to drive home for years.
