my country used the Long March 4B carrier rocket at the Taiyuan Satellite Launch Center to send the Environmental Disaster Mitigation II Group 01 satellites into the scheduled orbit in a "one arrow and two stars" method, and the launch mission was successful.
The 01 group of satellites of Environmental Disaster Reduction II includes two 16-meter optical satellites, which have the characteristics of high maneuverability, high-precision control, high stability, strong load adaptability and long life. After the satellite enters orbit, it will replace the overdue environmental and disaster monitoring and forecasting small satellites A and B, which can serve a wide range of users in land and resources, water conservancy, agriculture, forestry, earthquake and other applications, and further meet the country's continuous supply of data in related fields. .
