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.

Who Carries the Gold Standard Now?

January 28, 2014By
GNSS_opener

China’s BeiDou system claimed a user range error (URE) of 2.5 meters zero age of data (ZAOD) 95% recently.  The parallel GPS specifications commit to 6 meters 95% ZAOD and 7.8 meters 95% all AODs.  Does this mean that BeiDou is more accurate than GPS? Not so fast. In late December, director Ran Chengqi of China’s Satellite Navigation System Management... read more
