China Siwei
Chinese civilian remote-sensing constellation
From Wikipedia, the free encyclopedia
China Siwei Surveying and Mapping Technology Co. Ltd. (China Siwei) is a subsidiary of the China Aerospace Science and Technology Corporation (CASC), is a leading operator of Earth observation satellites in China. The company is specialized in providing Earth Observation data through its advance satellite constellation named Gaojing (SuperView)[1] and Siwei Gaojing (SuperView Neo) Series. The satellites are designed for high-resolution imaging for various applications. Siwei Gaojing constellation is a key component of Chinese commercial and civilian remote sensing capabilities, aiming to complete with global leaders, such as Maxar and Airbus.

Challenges and development
The SuperView-1 01 and 02 launch faced challenges due to an incorrect orbital insertion, requiring significant propellant use to correct its position and become operational, potentially shortening the satellites' operational lifespan.[15] Despite this, the constellation has grown steadily, with successful launch in subsequent years. The introduction of autonomous "Self-driving" satellite in 2024 marks a significant technology advancement.[16]
