April 29, 2022; At 04:11 UTC (00:11 EDT) today, CASC launches Two Remote sensing Satellites; SuperView Neo 1-01 and 02 from Jiuquan Satellite Launch Center (JSLC) aboard a Long March 2C (ChangZheng-2C) launch vehicle. The satellite successfully entered the predetermined orbit, and the launch mission was a complete success.

The Siwei's SuperView Neo 1-01 and 02 satellites provided by China Siwei Surveying and Mapping Technology Co.Ltd (China Siwei), a leading firm in providing RS satellite data and geospatial information services in China.

SuperView Neo (China Siwei/ CAST)

SuperView Neo 1-01 and 02, designed and developed by China Academy of Space Technology (CAST), are two commercial earth observation satellites of 0.5m resolution. The Satellites mainly serve in the traditional satellite remote sensing application industry such as resource and environment monitoring and management, ecological civilization construction, emergency management, etc., and also aim at the emerging market including smart water conservancy, 3D real scenes, urban information model, smart agriculture and intelligent transportation. It's 4D feature improves the agile imaging capability of the satellite by optimizing the configuration of the satellite attitude control and measurement components:

  • The front, lower and rear three-view stereo imaging can realize the 3D reconstruction of the ground target; the five-strip stitching imaging can realize a large area one-time rapid imaging Coverage.

  • The multi-target imaging method of 20 targets in the same orbit makes rapid monitoring possible

  • It further optimized linear ground object tracking, active push-broom imaging, and north-south push-broom imaging along the earth have greatly improved imaging efficiency and satellite data.

  • Acquisition capability; the high-efficiency data transmission system with large-capacity storage capability and the phased array antenna are used together to realize high-speed data download in fast maneuvering.
