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.

The Siwei's SuperView Neo 01/02 satellite is equipped with two high-precision space target imaging cameras, and the photosensitive pixels are replaced from traditional TDI CCDs to the most advanced CMOS devices. Image quality reaches new heights. As a follow-up series of Gaojing-1 satellites, the two cameras of the SiD-01/02 satellite have optimized it's total mass more than 60 kilograms, and the resolution has been continuously improved within the sub-meter level.

This mission is the 416th flight of the Long March series of launch vehicles, ( the sea launch of Long March 11 was cancelled before the launch) and the 12th launch of this year 2022 from China. LM-2C Launch Vehicle is a liquid two-stage launcher designed and manufactured by China Academy of Launch Vehicle Technology (CALT), a subsidiary of CGWIC. This is the 61st launch of LM-2C.

China Great Wall Industry Corporation (CGWIC) is a commercial organization authorized by PRC government to provide commercial launch services, satellite systems and to carry out space technology cooperation. Under the guidance of CASC (China Aerospace Science & Technology Corporation), CGWIC can provide fast, stable and reliable "one-stop" quality services to both international and domestic customers.

Since Long March launch vehicles entered the international market in 1990, CGWIC has completed 69 commercial launches for 69 international satellites (including 12 IOD communication satellites and 3 IOD remote sensing satellites) and 39 domestic satellites. In addition, CGWIC has conducted 42 rideshare missions, sending 27 international payloads (including 1 IOD remote sensing satellite) and 95 domestic payloads into orbits.
