TOKYO — Japan’s space agency said Sunday it successfully launched a navigation satellite on its new flagship H3 rocket as the country seeks to have a more precise location positioning system of its own.
The H3 rocket carrying the Michibiki 6 satellite lifted off from the Tanegashima Space Center on a southwestern Japanese island.
Everything went smoothly and the satellite successfully separated from the rocket as planned about 29 minutes after the liftoff, said Makoto Arita, H3 project manager for the Japan Aerospace Exploration Agency, or JAXA.
Officials said it is expected to reach its targeted geospatial orbit in about two weeks.
Japan currently has the quasi-zenith satellite system, or QZSS, with four satellites for a regional navigation system that first went into operation in 2018. The Michibiki 6 will be the fifth of its network.
Michibiki’s signals are used to supplement American GPS and will further improve positioning data for smartphones, car and maritime navigation and drones.
Japan plans to launch two more navigation satellites to have a seven-satellite system by March 2026 to have a more precise global positioning capability without relying on foreign services, including the U.S., according to the Japan Science and Technology Agency. By the late 2030s, Japan plans to have an 11-satellite network.
Sunday’s launch, delayed by a day due to the weather, was the fourth consecutive successful flight for the H3 system after a shocking failed debut attempt last year when the rocket had to be destroyed with its payload.
Japan sees a stable, commercially competitive space transport capability as key to its space program and national security and has been developing two new flagship rockets as successors to the mainstay H2A series — the larger H3 and a much smaller Epsilon system. It hopes to cater to diverse customer needs and improve its position in the growing satellite launch market.
