CZ-4B successfully sent four satellites to space, validating the grid fin system-based control technology of first sub-stage landing area
At 11:22 on November 3, CZ-4B launch vehicle was ignited at Taiyuan Satellite Launch Center and successfully sent GF-7 satellite of the High Resolution Earth Observation System Special Project (high resolution special project for short) to the intended orbit. The launch vehicle also carried delicate high resolution experiment satellite, Sudan scientific experiment satellite 1#, and Tianyi 15# satellite.
