The in-orbit validation of Galileo has been achieved, according to the European Space Agency (ESA). Europe now has the operational nucleus of its own satellite navigation constellation in place — the world’s first civil-owned and operated satnav system. Four is the minimum number of satellites needed to perform navigation fixes. In 2011 and 2012, the first four satellites were launched... read more

Switzerland Joins the EU’s Galileo Program

February 5, 2014By

Switzerland has signed a cooperation agreement to participate in the Galileo and EGNOS programs, the pillars of the EU’s Global Navigation Satellite System (GNSS). Switzerland will now fully financially participate in the programs, and will retroactively contribute €80 million for the period 2008-2013. The agreement, signed in Brussels December 18, 2013, also covers cooperation in areas such as security, export control,... read more

The System: Competition for the Gold Standard

February 1, 2014By
The main antenna of the second Galileo Full Operational Capability (FOC) satellite being inspected with a flashlight in advance of mass property testing at the European Space Agency’s  ESTEC Test Centre in the Netherlands. Thermal-vacuum testing on the second model began in early 2014. The two FOC satellites will be launched on a Soyuz rocket from Europe’s French Guiana Spaceport in mid-2014. Whether four more can rise and begin providing initial Galileo services by the end of the year is the question of the hour.

BeiDou Releases Public Service Performance Document In late December, director Ran Chengqi of China’s Satellite Navigation System Management Office announced the BeiDou Navigation Satellite System (BDS) Public Service Performance Standard. The document details the public service performance parameters of the BeiDou system, including service area, accuracy, integrity, continuity, and availability. It is a basic commitment to customers from BDS providers,... read more
