Ambitious future
Chinese scientists are not satisfied with the current regional coverage and the disadvantages of the Beidou system. The Beidou-II project began in 2007. As of December 2010, seven satellites for the Beidou-II have been launched, according to Xinhua.
"The Beidou-II will be able to provide passive positioning services next year and it will eventually become a system comparable to the US GPS," the insider predicted.
According to the April 2008 GPS World, the frequencies for the Beidou-II system overlap with the European Galileo satellite navigation project. The overlap has raised concerns on inter-system interference, especially within bands that are allocated for Galileo's publicly regulated service and military code.
The UN International Telecommunications Union rule is that the first nation to start broadcasting in a specific band will have priority and China launched the satellites first, the source claimed.
"The bandwidth is limited, and we have to act quickly," the source explained, adding that the overlap also means that in a possible conflict the hostile party could not jam Chinese signal without also jamming the EUs.
"With the growth of national strength, we need to act globally," they added, "Either you don't do it or you do it globally."
