Businesses engaged in rocket propulsion avionics, satellite components, sensors, communications equipment, software testing systems and space data analytics may also benefit from the project. The need for supporting technologies across the satellite and launch value chain is anticipated to rise as governments expand their space projects.

For this development, the Asia Pacific region is especially crucial. Precedence research claims that nations including South Korea, China, India and Japan are investing more in space exploration, communications networks and satellite launches. Thus, the regions expanding their commercial and government space technology ecosystems may benefit from Japan's ongoing H3 missions and QZSS expansion.

Impact on Satellite Market

The global satellite market size was estimated at USD 362.28 billion in 2025 and is predicted to increase from USD 391.99 billion in 2026 to approximately USD 780.24 billion by 2035, expanding at a CAGR of 7.97% from 2026 to 2035.

The development of satellite-based navigation infrastructure is directly aided by the launch of Michibiki 7. Japan's QZSS is intended to enhance positioning and timing services by integrating with GPS. Transportation logistics, mapping, agriculture, infrastructure management, emergency response and autonomous technologies all depend more on these capabilities.

Growing reliance on space-based technology by the military and government is another factor driving the satellite business. Key satellite applications include military surveillance, scientific research, commercial communications, navigation, and space observation, according to a precedent study.
