Science and Technology | Dated: 11 Sep 2025

On September 9, 2025, at 03:48 Beijing Time, GeeSpace, a Chinese space technology company, successfully launched 11 satellites for its Geli Constellation using the Smart Dragon-3 (SD-3) rocket. The mission was carried out from the Taiyuan Satellite Launch Center, near Rizhao city in East China’s Shandong Province.

🎯 Key Highlights:

  • - The Geli Constellation is owned by GeeSpace, a subsidiary of Gee Technology Group, and aims to establish a large-scale satellite network to provide Internet of Things (IoT) communication services to global users.
  • - In its first phase, the constellation will comprise a total of 75 satellites by the end of 2025, strengthening China’s role in the global commercial satellite communication sector.
  • - The 11 satellites launched were deployed into a Sun-synchronous orbit (SSO), which allows them to pass over the same region at consistent local solar times, enabling precise Earth observation and resource monitoring.

💡 Other Important Facts:

  • (i) The constellation’s purpose includes scientific research, land resource mapping, crop yield prediction, and disaster prevention and relief operations, contributing to agriculture, environmental monitoring, and emergency response.
  • (ii) The launch vehicle, Smart Dragon-3 (SD-3), was developed by the China Academy of Launch Vehicle Technology (CALT). It is a four-stage solid-propellant carrier rocket designed to deliver spacecraft to Sun-synchronous orbit or Low Earth orbit (LEO).
  • (iii) The SD-3 rocket has a payload capacity of 1.5 tonnes to a 500 km Sun-synchronous orbit. This launch marked its seventh flight mission, demonstrating growing reliability and China’s increasing launch frequency in the small satellite sector.
