(Yicai Global) July 6 -- China's communications satellite, ChinaSat-9A, has successfully entered the orbit powered by its own propeller. The successful entry comes after the first launch's failure last month, China Aerospace Science and Technology Corporation (CASC) reported today.
During the first launch on June 19, the satellite did not reach the orbit due to a problem with the carrier vehicle Long March 3B Y28 rocket.
With the assistance of Xi'an satellite monitoring center, CASC accurately performed 10 orbit adjustments, and ChinaSat-9A successfully reached its preset orbit at 101.4 degrees east longitude over the equator yesterday. All systems are operational on the satellite, and the transponders have been switched on. A series of in-orbit tests will be performed later, CASC said.
An anomaly was detected on the carrier rocket's rolling control thruster in the attitude control engine during the third gliding phase, reported a team of experts after conducting a thorough technical examination.
As China's first live radio and television broadcasting satellite, ChinaSat-9A will work with ChinaSat-9 to provide radio, TV, digital movie, digital broadband, multimedia systems and various information and entertainment broadcasting services for domestic users.
