Shenyang Academy of Instrumentation Science assisted to successfully launch Beidou Navigation Satellite

On October 25, 2012, China has successfully launched its 16th Beidou navigation satellite into space and sent it into transfer orbit through a Long March-3C rocket from the Xichang Satellite Launch Center. On December 27, Beidou satellite navigation system which is self-made and independently operates started the regional formal service, the Beidou system consisting of 16 navigation satellites will serve most Asia-Pacific region including China and surrounding area.

Since 2007, the Long March-3 series rockets have sent 16 Beidou satellites into the orbit through 14 launches. SAIS overcame and solved various key core technology problems through independent innovation, developed and manufactured dozens of aerospace precision bellows products of different specifications and models which are used for CZ-3A, CZ-3B, CZ-3C rockets for launch launching 16 Beidou satellites, and used for the key links such as regulation, control,etc. of high-temperature and low-temperature sealing valve systems for rocket engines, and fuel pipelines, strongly supporting the complete success of the satellite launch of Beidou navigation engineering.

The Beidou satellite navigation system is developed in three steps. The first step, building a Beidou satellite navigation test system in 2000; the second step, constructing a Beidou satellite navigation system, to form the service capability covering most Asia-Pacific region by the end of 2012; the third step, forming global covering capacity of the Beidou satellite navigation system.

According to the plan, the satellite launch of subsequent networking will be started in 2014. About 40 satellites will be launched within about 10 years,to form the global coverage capacity.

Thus, SAIS will further intensify technological innovation, and research aerospace precision bellows products having higher performance, to meet the requirement of subsequent Beidou satellite launch tasks to aerospace precision bellows products.
