At 23:46 on June 27, 2022, Beijing time, my country used the Long March 4C carrier rocket at the Jiuquan Satellite Launch Center and successfully put the high score Satellite 03 was launched on the 12th. The satellite successfully entered the scheduled orbit and the launch mission was a complete success.

The satellite is mainly used in areas such as land census, urban planning, land rights confirmation, road network design, crop yield estimation and disaster prevention and reduction.
The star arrows launched this time were all developed by the chief executive of the Eighth Academy of China Aerospace Science and Technology Corporation. The reporter learned from the institute that this rocket’s first flight has many new states: in order to adapt to the high-density launch model, the launch site process optimization was applied for the first time, the fully autonomous alignment technology that can independently identify the launch direction was applied for the first time, and it was applied for the first time at the Jiuquan Satellite Launch Center Digital boost control and newly developed equipment from Wai'an realize the unification of Jiuquan and Taiyuan Satellite Launch Center . The fully autonomous alignment technology applied to the
long four model for the first time has been verified by actual measured data from multiple launch sites. Compared with traditional optical aiming that transmits azimuth angle deviations, fully autonomous aiming relies on inertial group measurement data for real-time orientation calculation and computer automatic binding. This method reduces the risk of personnel transfer and is not affected by climate environments such as blowing sand, strong winds, and showers, and improves the rocket's versatility and adaptability.
