SHANGHAI - China will launch some eight Beidou navigation satellites by 2012, a leading navigation satellite expert said here on Wednesday.

上海——中国将在2012年前，发射8枚北斗导航卫星，一位导航卫星专家领导周三时在上海说。

China has sent eight Beidou satellites into orbit, as the latest was launched in April this year, said Ran Chengqi, director of China Satellite Navigation System management office.

He made the remarks at the second China satellite navigation academic annual meeting.

By 2020, about 35 satellites will form Beidou's global satellite navigation system, Ran added.
