China Successfully Launches Two High-Resolution Satellites Aboard Long March-2C.

Science and Technology | Dated: 03 Mar 2025

In February 2025, China successfully launched two new satellites, 'Siwei Gaojing-1 03' and 'Siwei Gaojing-1 04,' into sun-synchronous orbit approximately 500 kilometers (km) above Earth using the Long March-2C carrier rocket. The rocket was launched from the Jiuquan Satellite Launch Center in Northwest China.

🎯 Key Highlights:

  • - These satellites are equipped with high-resolution optical imagers and will be used for data collection to support natural resource management, urban planning, and other commercial applications.
  • - This launch marks the 561st flight mission of the Long March carrier rocket series.
  • - In February 2025, China successfully launched two high-resolution satellites, 'Siwei Gaojing-1 03' and 'Siwei Gaojing-1 04', into a 500 km sun-synchronous orbit using the Long March-2C rocket from Jiuquan Satellite Launch Center. These satellites will support natural resource management, urban planning, and commercial operations.

💡 Other Important Facts:

  • (i) The satellites are part of the China Siwei New Generation Commercial Remote Sensing Satellite System (SuperView constellation), operated by China Siwei under CASC. The Shanghai Academy of Space Technology (SAST) developed these satellites, adding to the existing 9-satellite constellation deployed in near-polar orbits.
  • (ii) Developed by CALT (China Academy of Launch Vehicle Technology), the Long March-2C is a two-stage launch vehicle with storable propellants.
  • (iii) It measures 43 meters in length, 3.35 meters in width, and has a lift-off mass of 242.5 metric tons (MT). This mission marks the 561st flight of the Long March series.
