China Successfully Launches Yaogan-46 Satellite

China has successfully launched the Yaogan-46 satellite using a Long March-7A carrier rocket from the Wenchang Space Launch Site on November 3, 2025. The satellite, developed by the Fifth Academy of China Aerospace Science and Technology Corporation, is designed for disaster prevention and mitigation, land and resources surveying, and water conservancy and meteorology. The model development team implemented strict quality control measures and continuously optimized the development process to ensure success.

Key Takeaways:

• The Yaogan-46 satellite was launched using a Long March-7A carrier rocket from the Wenchang Space Launch Site on November 3, 2025.
• The satellite is primarily developed by the Fifth Academy of China Aerospace Science and Technology Corporation and is used for disaster prevention and mitigation, land and resources surveying, and water conservancy and meteorology.
• The model development team implemented strict quality control measures and adhered to the principle of "quality first" to ensure success.
• The team continuously optimized the development process and went all out to win the battle, faithfully shouldering the responsibility and working together to ensure success.
• Despite facing high technical difficulty and tight development time, the team strictly implemented relevant requirements and simultaneously focused on quality and ensuring progress.
• The model development team thoroughly applied product assurance methods, fully integrating organizational-level risk control into the entire development process.
• The team specifically planned risk control and quality verification work, carrying out the "four checks, three comparisons, and two considerations" approach and inviting experts in the field to conduct on-site briefings and oversight on key on-orbit operations of the satellite.
• The team successfully managed the deployment and allocation of test team personnel, ground testing equipment, and tooling, ensuring that mission progress was not affected and that personnel and products were safe.
• Going forward, the model development team will uphold the principles of "quality first" and "responsibility as if it were life itself," aiming to ensure the stable operation of the satellite in orbit.
