China launched its fifth Beidou orbiter into space on Sunday morning, moving it one step closer to its goal of building a navigation(导航) and positioning satellite network.
The Beidou, or Compass, system is being built to rival the US-developed GPS, the European Union's Galileo and Russia's Global Navigation Satellite System. It can allow travelers, drivers and military officials to know their locations.
The fifth orbiter was launched on top of a Long March 3A carrier rocket at 5:30 am on Sunday from Xichang of Southwest China's Sichuan province.
It is the third Compass satellite launched this year, following launches on Jan 17 and June 2.
The short interval of less than two months since the last launch demonstrated that "the country is stepping into a busy period of launching the Compass satellites", an unnamed official in charge of the project said last month.
The first two orbiters were launched in 2007 and 2009 respectively.
Sun Jiadong, the Beidou program's chief designer, said on June 21 in a TV interview that China would launch 13 to 15 Beidou navigation satellites into orbit by 2012 to form a network that provides regional service covering the neighboring areas.
And in about 10 years, the network would be expanded to include more than 30 satellites covering the globe, he said.
The system is a crucial part of the country's space infrastructure for providing navigation and positioning services in transportation, meteorology, petroleum prospecting, forest fire monitoring, disaster forecasting, telecommunications and public security.
In addition, a global positioning system is crucial to any country's national security and defense, said Ran Chengqi, an official in charge of the program, referring to the fact that the US initially built its GPS system for military purposes.
It is unimaginable for China to go without such a system, he said.
Earlier reports cited（引用） Song Xiaojun, a Beijing-based military expert, as saying that 90 percent of the world's current weapons systems need a global positioning system.

Most 23-year-olds have not done enough in life to be worthy of having their own documentary（纪录片）
Most 23-year-olds aren't LeBron James.
The NBA superstar, who recently won gold at the Beijing Olympics, has just released More Than a Game. It is a documentary that follows his rise to stardom (明星地位) and how he and four childhood friends overcame long odds to win a national championship in high school.
Combining footage (镜头) taken during James' career at St. Vincent-St. Mary High School in Akron, Ohio, US, along with one-on-one interviews by writer/director Kris Belman, home videos, and personal family photographs, the film is about much more than basketball. At its core (核心) is a story of friendship, loyalty and love.
"We set out with a goal as kids and we wanted to accomplish that someway, somehow by using basketball as a tool, not knowing that it was going to create other opportunities for us," James said. "We didn't know it was going to create a brotherhood and trust. We grew from kids into young men."
While James is the star, his former teammates, Dru Joyce III, Sian Cotton, Willie McGee and Romeo Travis, play a major role in the film.
Their journey began together as 8-year-old boys, winds through years traveling all over America playing in basketball tournaments and finishes in their senior season at St. Vincent-St. Mary High School.
At the time, Belman was a college film student. He set out to film James and his friends' season as his final school project, a 10-minute documentary. But after gaining the trust of the players and coach Dru Joyce, Belman spent two months filming and eventually teamed with producer Harvey Mason Jr to the full-length feature.
James hopes the film will inspire youngsters (年轻人).
"We set out with a goal when we were eight and we accomplished it when we were 18," he said. "It's a great story and I wanted to get it out to kids that have a dream, that they should continue to go after it, believe in it and live it if they want to accomplish something."
