1997 December 8, 2011 3:00 pm Shiliu Sishi Jiudian five seconds, independently developed by China's "long-dipropyl improved carrier rocket from the Taiyuan Satellite Launch Center launch liter Empty successfully manufactured by Motorola, Inc. in the United States two iridium satellite into orbit.
This is the forty-ninth launch of the first commercial launch of China Great Wall Industry Corporation contract Iridium satellite launch contract, also a Long March series of carrier rockets. used to launch the "long dipropyl improved rocket,
about 40 meters, the rocket body, maximum diameter of 3.35 meters, the take-off mass of two hundred and thirteen tons. Rocket about 50 minutes after the flight, the distributor orbit successfully, has two Iridium release six hundred twenty-nine km perigee and apogee six hundred thirty-two km, inclination of 86.3 degrees, nearly round track. the
Iridium global satellite personal communications system designed by Motorola in the United States, is composed of 66 satellites from Earth height of about seven hundred kilometers of track laying, in accordance with the six running surface to achieve low orbit a small satellite communications. China Great Wall Industry Corporation and the U.S. company Motorola launch contract was signed in April 1993. The launch, in recent years, will be carried out 10 launches addition networking and mending their nets twenty Iridium orbit a stone double star way. U.S. Delta and Russian Proton rocket launch of the Iridium system contract.
this launch, the Taiyuan Satellite Launch Center in the first implementation of the international commercial launch. After three decades of building this center have the ability to launch various types of polar-orbiting satellites, and has succeeded in two "Fengyun satellite into space. (History. Cn)
