Global Navigation Satellite Systems Engineering, Policy, and Design
The next decade’s aircraft pilots will be able to rely on enhanced, reliable GNSS satellite navigation signals on a seamless basis across much of the world, thanks to decisions made at the latest gathering of worldwide GNSS augmentation system providers and experts.

Trimble’s BD935-INS (left) and BX-935-INSTrimble has introduced the BD935-INS module that combines a multi-frequency, multi-GNSS receiver with an integrated 3-D microelectromechanical systems (MEMS) inertial sensor package.
As part of Trimble’s GNSS OEM portfolio, the new compact module augments real-time precise positioning with 3-D orientation, connectivity, and configuration capabilities designed to enable system integrators and OEMs to add GNSS and attitude to specialized or custom hardware solutions.

Registrations are still available for the this year’s European Space Agency (ESA) International Summer School on Global Navigation Satellite Systems, which will take place in Barcelona, Spain, at the end of August.
NovAtel GPS-704-WB antennaNovAtel Inc. today (April 23, 2015) launched the GPS-704-WB antenna, a wideband antenna that supports L-band as well as the frequencies of all current GNSS constellations (GPS, GLONASS, Galileo, and BeiDou), including B3 and E6 signals. Customers can use this antenna for GPS-only or multi-constellation applications, providing excellent flexibility for application developers, according to the company.

The 2015 edition of the European Navigation Conference (ENC) in Bordeaux last week found the continent’s GNSS community leaving troubles behind and looking to the future, where the world’s dependence on GNSS is greater, the risks higher, and the potential profits ever more tantalizing.
Speaking at the opening session dedicated to “the impact of GNSS on the economic sector,” Topos Cluster President Florence Ghiron answered the question in the simplest of terms: “We expect the GNSS market to grow and to include more and more industrial sectors.”
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).

A Long March-3C rocket carrying a new-generation satellite for the BeiDou Navigation Satellite System (BDS) blasts off from the Xichang Satellite Launch Center in the southwest China’s Sichuan Province, March 30, 2015. Xinhua photo by Bai YuChina’s Xinhua news agency has announced the launch a new-generation BeiDou satellite at 9:52 p.m. Beijing time yesterday (March 30, 2015).
This is the first of five next-generation BeiDou spacecraft that China will launch this year, Jianyun Chen, a deputy director of the China Satellite Navigation Office (CSNO), told a Munich Satellite Navigation Summit last week.

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.

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.
