hackingbear writes "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 full fledged, competitive, and encrypted system by 2010.

Like GPS, Galileo and Glonass, Beidou/Compass would be free of direct user charges but also feature an encrypted signal for authorized users only, presumably including the Chinese military.

Beidou/Compass is designed to feature five satellites in geostationary orbit and 30 satellites in medium Earth orbit. Ran and Xiaohan Liao, a deputy director at China's Ministry of Science and Technology, said the first of the medium Earth orbit satellites, launched in April 2007, is functioning well but is still the subject of in-orbit validation.

Liao said China intends to operate a Wide Area Precise Pointing system using geostationary satellites. China operates three Beidou/Compass satellites in geostationary orbit. Liao said the wide-area coverage, to include all of Asia, should be in operation by 2010.
