China Launches Geely-04 Satellite Constellation to Boost IoT and Vehicle Communication Services.

Science and Technology | Dated: 16 Aug 2025

In August 2025, China successfully launched the fourth batch of Geely-04 satellites under the Geely Future Mobility Constellation (GEESATCOM) to enhance global Internet of Things (IoT) connectivity, maritime operations, and inter-vehicle communication. The mission involved 11 Low Earth Orbit (LEO) satellites deployed via a Smart Dragon-3 (SD-3) rocket from an offshore platform near Rizhao, Shandong Province.

🎯 Key Highlights:

  • - The mission was executed by Geespace, the commercial aerospace subsidiary of Zhejiang Geely Holding Group, with satellite launch operations conducted from the Taiyuan Satellite Launch Center. Geespace has been operating its LEO constellation since 2018 with a focus on autonomous driving, high-precision positioning, and IoT services.
  • - With this launch, Geespace expanded its Geely-04 GEESATCOM IoT constellation from 30 to 41 satellites. The company aims to complete the deployment of a 72-satellite network by the end of 2025, enabling seamless global IoT coverage.
  • - The Smart Dragon-3 (SD-3) rocket, also known as the Jielong-3, served as the launch vehicle. Measuring 31 meters in length, 140 tonnes in weight, and using solid propellant, the SD-3 is capable of delivering payloads of up to 1,500 kilograms into a 500-kilometer Sun-Synchronous Orbit (SSO).

💡 Other Important Facts:

  • (i) Developed by the China Academy of Launch Vehicle Technology (CALT), the SD-3 rocket is designed for rapid deployment and cost-effective space missions. This launch marked the sixth flight of the SD-3 series, further solidifying its reliability for commercial satellite missions.
  • (ii) The Geely LEO Satellite Programme supports various applications, including maritime monitoring, autonomous vehicle navigation, and remote sensing. These satellites enhance real-time data transfer between land, sea, and air-based systems, benefiting sectors like transportation, logistics, and public safety.
  • (iii) China’s accelerated deployment of the Geely satellite constellation is part of its broader strategy to lead in global space-based IoT services. The initiative also strengthens China’s commercial space sector, aligning with the country’s long-term space and technology development goals.
