Slashdot discuss a Space.com article on the upcoming Chinese GPS/Glonass/Galileo competition named Beidou. Their summary:
"Unsatisfied by the reliance of American GPS navigation system and not feeling much security joining the European Galileo system, China will expand its 4-satellite Beidou navigation system to a full-fledged, competitive, and encrypted system by 2010."
See related stories below, Beidou, also known as Compass, was discussed several times before.

China's Compass Satellite Navigation System? 1 comment

Very Spatial links to an interesting Defense Tech article regarding China's potential answer to USA's GPS, Europe Galileo and Russia's Glonass navigation satellites named Compass. From the article: "China invested in the European Galileo system through the Galileo Joint Undertaking. [...] It’s no surprise, then, that China would feel betrayed by its partnership in the Joint Undertaking. Compass may be a result of China’s desire to strike out on its own– or a bluff aimed at wrangling a more substantive role in Galileo. [...] Another consideration: there is a possibility that Compass could jam GPS and Galileo. Even as a regional system, Compass could have significant military implications"
China's Compass Diverges from Europe's Galileo
[+]
the SM-GIS blog links to a Space Review article on Europe's Galileo and China's Compass. From the article: "For the Chinese, Galileo is no longer a partner, but instead more of a competitor. They extracted as much as they reasonably could have out of their relationship with the Europeans over this and now have decided to strike out on their own. [...] China was invited into Galileo partly as a way to snub the US and partly because the Europeans seem to believe that the more “international” a project is the better chance it has of not being canceled."
Chinese GPS System to be Offered Free 1 comment

Slashdot discuss the Chinese Beidou geostationary GPS system to be offered free. Their summary: "The Chinese GPS system, Beidou, is apparently to be opened up for free access within China, worrying European investors on the 2.5 billion competing project, Galileo. Initially, China had declared that access to their system would be restricted to the military, and Europe had planned to recoup some of the cost of their system selling licenses to China. Michael Shaw, from the US government's National Space-based Positioning, Navigation and Timing Coordination Office in Washington DC said "Frankly, China's behavior towards Europe is not so different to how Europe behaved with us when GPS was the only game in town a decade ago."
China Launches First GPS Rival Satellite
[+]
All Points Blog tells us China has successfully launched their first Compass GNSS satellite which will compete with other GPS systems. From the short article: "The Chinese Compass Navigation Satellite System will provide positioning signals across China by 2008, and will eventually be extended worldwide.
Experts said that the system is operating well and has played a significant role in cartography, telecoms, water conservation, transportation, fishery, prospecting, forest fire monitoring and national security." There's the orbit technical details in the JSR space report. See also related stories.
