Geoscience Australia, Lockheed collaborate on multi-GNSS SBAS research

February 13, 2017By
To improve precision navigation, a second-generation SBAS will use signals from both GPS and Galileo, and dual frequencies, to achieve even greater GNSS integrity and accuracy.

Geoscience Australia, an agency of the Commonwealth of Australia, and Lockheed Martin have entered into a collaborative research project to show how augmenting signals from multiple GNSS constellations can enhance positioning, navigation and timing for a range of applications. Other partners are Inmarsat and GMV. The research project aims to demonstrate how a second-generation Satellite-Based Augmentation System (SBAS) testbed can... read more

australia-T

The Australian Government will invest $12 million in a two-year program looking into the future of positioning technology in Australia. The funding includes testing of satellite-based augmentation systems (SBAS) that can offer instant, accurate and reliable positioning technology. The improvements in positioning could provide future safety, productivity, efficiency and environmental benefits across many industries in Australia, including transport, agriculture, construction and resources. The... read more

This article is based on a presentation to the National Space-Based Positioning, Navigation and Timing Advisory Board in June 2015. The study reported on at the meeting was requested by the National Executive Committee for Space-Based Positioning, Navigation and Timing. It demonstrates the widespread use and importance of GPS to the U.S., with estimated benefits in 2013 of about $56... read more

GSA’s 2015 Report Dives Deep into Global GNSS Market

March 27, 2015By
FIGURE 2. SUPPORTED CONSTELLATION BY RECEIVERS Chart shows the percentage of available
receivers capable of tracking signals from one GNSS (such as GPS only), two GNSS (GPS
+ Galileo, GPS + GLONASS, GPS + BeiDou), three GNSS (GPS + Galileo + GLONASS, GPS +
Galileo + BeiDou, GPS + GLONASS + BeiDou) or tracking signals from all constellations at
the same time. The percentages add up to 100 percent. We can conclude that almost 60
percent of all available receivers, chipsets and modules are supporting a minimum of two
constellations, showing that multi-constellation is becoming a standard feature across all
market segments.

2015 GNSS Market Report: European GNSS Agency Provides a Fresh Look at Worldwide Growth The fourth edition of the European GNSS Agency’s (GSA’s) GNSS Market Report provides a comprehensive source of knowledge on this dynamic global market. The report has become a key reference for organizations building their GNSS market strategies. The new edition provides: Comprehensive updates on previous analyses;... read more

Synergies between Europe’s Rail and SatNav Programs Can Make Rail Travel Affordable

March 28, 2014By

Cost-effective synergies between the European Rail Traffic Management System (ERTMS) and satellite technologies such as Galileo can make rail transport more efficient and reliable, agreed European authorities in February at a Rail Forum Europe dinner in Brussels. But while the technology is now available, its implementation pace is still too slow due to the long term return on investment. Francesco... read more
