Low latitude location advantage. Hainan is the closest province to the equator and the lowest latitude in China. When launching geosynchronous orbit satellites from Wenchang launch site, the orbit distance is relatively short, so we can make full use of the satellites rotating on the earth, reach the scheduled orbit with less energy consumption and save a lot of fuel consumption. Satellite life can be extended by more than 2 years.
The advantages of convenient transportation. Large rockets are not convenient for road and rail transportation, but Wenchang can greatly reduce these disadvantages. Wenchang Satellite Launch Center is located in the northeast of Hainan, with beautiful coastline and excellent port, so all the rockets used by Wenchang Satellite Launch Center are transported to Wenchang Qinglan Port by sea.
Security advantage. In Jiuquan, Taiyuan and Xichang launch centers, a large number of residents should be temporarily placed for each rocket launch to prevent local residents from being injured when the first-class rocket falls. Wenchang Satellite Launch Center is near the sea. After the rocket was launched, its first-stage rocket crashed into the South China Sea, which not only avoided the personal safety of residents, but also avoided the damage to the ground, greatly improving the safety of debris falling.
