Wang Jing told a press briefing in Beijing yesterday that his company, Xinwei Telecom Enterprise Group, launched a low-earth orbit satellite last month in Inner Mongolia in a joint venture with Tsinghua University.
It makes Xinwei the first private enterprise in the country to invest in the closely guarded space industry, Wang said.

The satellite, developed with Tsinghua University, was expected to provide a cheaper alternative to foreign satellite communication providers in China's sea and desert areas, Beijing News said, citing Tsinghua Professor Lu Jianhua.
Wang said Xinwei planned to develop four more satellites with the university and build a telecommunication "constellation" over the next 10 years, the report said.
"The cost of building the satellites with homegrown technology is very low and so we have high expectations on the return on investment in the future," Wang was quoted as saying.

[machine translation follows] On the 26th, Tsinghua University and Xinwei Group jointly announced: China's first low-orbit satellite mobile communications – smart communications test satellite (hereinafter referred to as smart) has completed all the success in-orbit testing test engineering tasks.
Industry sources said the trial is successful this private satellite, indicates that China has not only achieved LEO satellite mobile communication technology an important breakthrough for the construction of a key step towards the constellation communications system, also created a collaborative innovation of private enterprises and universities to participate in aerospace The new mode of communications.
For the national strategic needs, private enterprises and universities together to test the water space communications.
According to reports, smart communications test satellite weighs about 130 kg, runs on an altitude of about 800 km sun-synchronous orbit.
... the absence of its own low-orbit communication satellites, currently more than 80 percent of China's land area, the communication network covering more than 95% of marine areas are still facing problems, fishermen, ocean sailing, mountainous forest operations yet inexpensive and effective . Thus, through innovation, build self-control, security and sustainable development in the constellation communications system, has become an urgent strategic needs. Meanwhile, the constellation communications system needs to have dozens of satellites joint operations in order to achieve full coverage of communication. Therefore, the establishment constellation communications system is not only huge investment, and technical difficulties, the risk is high.

The Ling Qiao, China's first low-earth-orbit communications satellite (comsat), designed by Beijing's Tsinghua University and Xinwei Telecom Enterprise Group, has completed its orbit test, marking a breakthrough for China, reports the website of China's Global Times.
Weighing 130 kilograms, the satellite runs at a Sun-synchronous orbit with an altitude of about 800 kilometers, covering an area 2,400 km in diameter. China launched the satellite with the Long March 2A rocket from the Jiuquan Satellite Launch Center Sept. 4, starting an in-orbit test communications task between mobile phones and hand-held GPS devices.
