Tiantong-1 02 was successfully launched. China used Long March 3B in xichang satellite launch center and successfully put Tiantong-1 02 into the scheduled orbit. ?

The satellite was developed by China Academy of Space Technology under China Aerospace Science and Technology Corporation. The key technologies have independent intellectual property rights, and provide full-time and stable mobile communication services, including voice calls, short messages and data services, to users in China and its surrounding areas and most parts of the Pacific Ocean and Indian Ocean. This satellite optimizes the satellite platform and load according to the use requirements, enhances the flexibility, improves the utilization rate of resources, and realizes the technical breakthrough of integrated management of satellite-ground resources and multi-satellite joint control.

After the successful launch of Tiantong-1 02 satellite, Tiantong-1 0 1, which has been running stably for 4 years, will form a satellite mobile communication system in the Asia-Pacific region with subsequent satellites. Taking advantage of the wide coverage area of satellite communication to supplement the ground mobile communication, this communication system will also serve as the basic network core of China's emergency satellite communication and improve China's ability to deal with emergencies.

The successful launch of the satellite is inseparable from the conscientious scientists behind it. On the penultimate day before the satellite launch 1 1, the cryogenic power commander heard an abnormal sound after the test equipment was running. After additional tests, it was found that the place where the air leakage sound occurred was the hydrogen vent. He quickly reported to the launch site command, and the command immediately made a judgment, and proved that the equipment was unreliable by analyzing the data, and organized the replacement of the valve overnight, which solved the quality problem of the equipment. Later, when this process was continued, an unexpected situation appeared: the leakage rate of the pressure measuring check valve of No.3 supercharger was too large. This problem is very serious. If this happens again before launch, the connector will fall off, causing fuel overflow, which may cause explosion when encountering sparks, and the operator may be poisoned by inhaling unsymmetrical dimethylhydrazine. After discussion, the headquarters decided to strictly control, replace the seven-tube connector socket, and do relevant tests, so as to efficiently complete the secondary insulation disposal, electrical test verification, accuracy test and other work of the satellite power controller, ensure that the products on the rocket are in good condition, and eliminate many hidden dangers. This meticulous spirit and efficient cooperation with scientists and headquarters enabled the satellite to be successfully launched. ?
