_China successfully completed its third Space Mission of the year – launching a Long March 3C Rocket from the Xichang Satellite Launch Center to orbit a Compass-G satellite.
Launch took place at 16:12 UTC and the Long March 3C Rocket performed as expected and delivered the Payload to Geostationary Transfer Orbit as planned. Spacecraft separation occurred about 26 minutes after liftoff. This marked the 8th flight of the CZ-3C Configuration and the 158th Long March Flight.
The Compass-G Satellite System is China’s second-generation Satellite Navigation System to support China’s goal of developing a global navigation system similar to GPS. The system is used by civilian users as well as authorized and military customers that have access to the high accuracy measurements provided by the satellites. Public accuracies are 10 meters in position and 0.25 meters per second in velocity. The Satellite is based on the DFH-3 Satellite Bus which is a flight-proven satellite design that includes power, communication and stabilization systems. It had a liftoff mass of 3,800 Kilograms. The satellite is also called Beidou-2 and is expected to operate for 12 to 15 years. A global navigation capability will be provided by 2020 – according to Chinese Media. In its firat stage, the system provides navigation fpr China and surrounding regions after satellites underwent testing and checkouts. When complete, the constellation will consists of 35 Spacecraft. The Beidou System started to provide services for testing purposes on December 27, 2011 after the first Beidou Satellite was launched on December 1st.
