According to the Xinhua news agency, China's satellite navigation system launched a positioning service on Tuesday. China started building its space-based navigation system in 2000 in order to stop having to rely on the U.S. Global Positioning System (GPS). The Beidou navigation system is now providing services for China and "surrounding areas," according to the Xinhua report. Beijing will launch another six satellites in 2012 to expand it to most of the Asia-Pacific region. The...

More Accurate Than Santa Claus

First Galileo satellite orbit determination with high precision Every year for Christmas, the North American Air Defense Command (NORAD) posts an animation on their website, in which the exact flight path of Santa Claus' sled led by reindeer Rudolf is precisely located. The path of navigation satellites, however, has to be determined much more accurately than Santa's flight path, when precise ground positioning is required. GPS is the best known system of this kind, the European system...

Europe´s Galileo system has passed its latest milestone, transmitting its very first test navigation signal back to Earth. The first two Galileo satellites, launched on 21 October, are in the midst of their In-Orbit Test campaign. A detailed check-up is being carried out by ESA's Redu ground station in Belgium to ensure their payloads are performing as specified, with no degradation from the launch. The different Galileo signals are being activated and tested one by one. Soon after...
