Kuaizhou 1A | Traffic VDES A & B
Kuaizhou 1A • Kuaizhou
📝 Mission Description
This Kuaizhou 1A launch carries the Kuaizhou 1A | Traffic VDES A & B mission, scheduled for December 05, 2025. The mission aims to deliver important payloads to orbit, contributing to our understanding of space and advancing technological capabilities.
ℹ️ Official Details
Two technology demonstration satellites for satellite transmissions of signals for the VHF Data Exchange System (VDES), a successor to the current Automatic Identification System (AIS) on ships and maritime vessels for traffic management at sea with higher bandwidth on new frequencies for secure communications and e-navigation.
This project is a joint effort by the China Ministry of Transport's China Transport Telecommunications Information Center and SpaceSail, operator of the Qianfan/G60 constellation.
🎯 Post-Launch Analysis
Post-Launch Analysis: Kuaizhou 1A | Traffic VDES A & B Mission (December 05, 2025)
The Kuaizhou 1A launch on December 05, 2025, executed flawlessly, achieving successful orbital insertion and payload deployment of the Traffic VDES A & B satellites. Technical performance of the solid-fueled Kuaizhou 1A rocket demonstrated precision in trajectory and staging, reinforcing its reliability for rapid-response, low-cost missions. The two technology demonstration satellites, designed for VHF Data Exchange System (VDES) transmissions, were placed into their target orbits with nominal separation, validating deployment mechanisms and onboard systems. This mission marks a critical step in validating VDES as a high-bandwidth successor to AIS, enhancing secure maritime communication and e-navigation. Engineering lessons include confirmation of payload integration robustness and frequency management for VDES signals. Strategically, this success, driven by the China Ministry of Transport and SpaceSail, strengthens the Qianfan/G60 constellation framework, paving the way for expanded maritime traffic management and global navigation solutions in future missions.
