Visualizing the Flight of Japan’s H3 Rocket
Translating Telemetry into an Intuitive Flight Experience
Developed as the successor to the H-IIA, the H3 rocket serves as Japan’s new flagship launch vehicle. The H3 FIP was designed to deliver accurate, high-quality updates on the rocket’s flight status in real time, helping viewers follow the launch as it unfolds.
By receiving telemetry directly from the rocket, the system visualizes both numerical data—such as velocity and altitude—and spatial data like planned trajectories and actual flight paths. This allows audiences to grasp complex technical information through a clear, intuitive visual interface.
Leveraging modern web technologies such as WebGL and WebSocket, the system was built using TypeScript, React, Cesium, and Three.js.
This simulation illustrates a launch into a sun-synchronous orbit (SSO).
The actual trajectory is shown as a dark solid line, while the planned trajectory is represented by a lighter solid line.
