The Japan Aerospace Exploration Agency (JAXA) has successfully launched its fifth H-3 rocket, which is carrying the Michibiki No. 6 satellite. This satellite will enhance Japan’s positioning system, an essential component of its own version of the U.S. Global Positioning System (GPS). The launch occurred at 5:30 p.m. from the Tanegashima Space Center located in Kagoshima Prefecture, and the satellite was successfully positioned into its intended orbit.
The Michibiki satellite series plays a vital role in Japan’s space infrastructure. It delivers high-precision location data with centimeter-level accuracy, which is essential for the country’s future independence in navigation systems. Japan aims to have seven Michibiki satellites operational by fiscal 2025, with plans to eventually expand to 11, thereby reducing its dependence on external GPS sources. The H-3 rocket, developed by JAXA and Mitsubishi Heavy Industries, has achieved success after overcoming a setback in 2023, and its upcoming launches will be critical for Japan’s space ambitions.
