China Siwei
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 it's 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 capabilites, aiming to complete with global Leaders, like Maxar and Airbus.
Overview
China Siwei operates 14 Satellite under Gaojing and Siewi Gaojing constellation and planned to add 18 more Satellites into its constellation. The Constellation is divided into three series: SuperView Neo-1,[2] SuperView Neo-2[3] and SuperView Neo-3.[4]

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 shorteningthe 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]
