China launched a new synthetic aperture radar (SAR) imaging satellite called Gaofen-3 from the Taiyuan Satellite Launch Center in northern Shanxi Province.
According to Xinhua, the satellite, which was launched on a Long March 4C, is equipped with a radar payload that can produce high-resolution images of one meter. It will be used for civil applications such as 24-hour environmental monitoring, weather forecasting, disaster monitoring, and water resource assessments.
key points:
- “The launch of Gaofen-3 is expected to reduce dependence on data provided by foreign microwave imaging satellites,” Jiang XIngwei, deputy chief engineer of Gaofen satellite application system, said.
- IBTimes reported that Gaofen-3 would also be utilized to protect China’s maritime rights interests especially with the growing tension in the South China Sea. “The satellite will play an important role in monitoring the marine environment, islands and reefs, and ships and oil rigs,” Xu Fuxiang, head of Gaofen-3 project, said.
- The new satellite was developed by Beijing-based China Academy of Space Technology and has a lifespan of eight years. Boasting of its 12 imaging modes, Gaofen-3 is the best player among the SAR family as it can easily switch into different settings, with the ability to take photos on land or water and detailed photos of particular locations.
- Gaofen-3 also features spatial resolution ranging between 1 meter and 400 meters, and its broadest viewing spectrum could reach up to 65- kilometers. It can reportedly produce clear photos of all roads, buildings, and boats, Shanghai Daily reported.
- This is the first Chinese satellite that will cater to civilian users and would “serve many different needs of many different users.
