Combining Galileo with GPS and GLONASSWhile a GPS-based GBAS will offer improved navigation services for aircraft, might these services be even better if the systems were to use satellites from other constellations besides GPS? In this month’s column, the authors show how GBAS protocols might be modified to accommodate multiple constellations, offering results of preliminary tests using GPS, GLONASS, and Galileo simultaneously. read more
This spring, two Brussels conferences focused on new possibilities and modes of transport enabled by satellite navigation, showing the added value delivered by current and future European GNSS solutions. read more
In the mass market, individuals around the world are creating vast quantities of location data and GPS traces using not only GPS, but also Russia’s GLONASS, Europe’s Galileo, China’s Compass, and India’s Regional Navigational Satellite System. The value of this data and the value chains that produce it will increase significantly with an increase in interoperability of these satnav systems. Currently, non-interoperability represents a serious obstacle to the growth of the GPS market. read more
The 2013* Conference, April 13-17, 2014 This month’s column is a short one since I’m attending GEOINT 2013* in Tampa. The asterisk on 2013 is a way for USGIF to save a few bucks by not reprinting banners, displays and handouts for the 2014 date. In talking to the USGIF staff, I learned this will be the only symposium for... read more
Supergeo Technologies, a global provider of GIS software and solutions, officially released SuperGIS Engine 3.2 to assists GIS developers in customizing GIS applications to meet diverse requirements of each project. Developed by Supergeo through integrating mapping and GIS technologies, SuperGIS Engine 3.2, as the COM-structured development component, provides developers with complete GIS core components. The developed applications can be seamlessly... read more
In an unprecedented total disruption of a fully operational GNSS constellation, all satellites in the Russian GLONASS broadcast corrupt information for 11 hours, from just past midnight until noon Russian time (UTC+4), on April 2 (or 5 p.m. on April 1 to 4 a.m. April 2, U.S. Eastern time). This rendered the system completely unusable to all worldwide GLONASS receivers.... read more
