Chinese satellite navigation officials say they intend to field an operational system covering all of Asia by 2010, but they are giving few details on the deployment plans for their global system. In addition China has yet to complete frequency coordination with the United States, Europe, Russia and others.
A commercial satellite image appears to have captured China's new nuclear ballistic missile submarine. The new class, known as the Jin-class or Type 094, is expected to replace the unsuccessful Xia-class (Type 092) of a single boat built in the early 1980s.
The launch over the weekend by China of a navigation satellite , its first for four years, could signal the country's challenge to the American Global Positioning System (GPS) and Europe's fledgling Galileo network, in which China is already a partner.
China has launched its first navigation satellite in nearly four years, taking a step forward in its drive to develop a positioning system intended to eventually rival Washington's GPS and Europe's Galileo.
U.S. intelligence agencies believe that China has successfully tested an anti-satellite weapon by destroying one of their old weather satellites. The test, if confirmed, would be an order of magnitude more provocative than earlier reports of Chinese blinding lasers being used against U.S. satellites.
China's decision to expand the functionality of its satellite navigation network could undermine the economics of Europe's nascent Galileo system, according to sources close to the project.
Gen. James Cartwright, the top U.S. military officer in charge of operations in space, says the United States has not seen clear indications that China has intentionally disrupted American satellite capabilities.
China has secretly fired powerful laser weapons designed to disable American spy satellites by "blinding" their sensitive surveillance devices.
China has fired high-power lasers at U.S. spy satellites flying over its territory in what experts see as a test of Chinese ability to blind the spacecraft, according to sources. It remains unclear how many times the ground-based laser was tested against U.S. spacecraft or whether it was successful.
