– To be supplied for all 7 next-generation Earth observation satellites by Japanese space startup 'Axelspace' – Slated for launch in July 2026 aboard a Falcon 9 rocket, enabling daily high-precision monitoring of identical regions
Nikon, a legendary name in optics, is further solidifying its presence in the space observation business, expanding far beyond consumer camera lenses.
According to space industry sources and Nikon Rumors on the 19th, Nikon's custom-built space telescopes have been selected to power all seven next-generation Earth observation satellites, known as ‘GRUS-3’, developed by Tokyo-based microsatellite startup Axelspace.
Identifying Aircraft Models from 585 km Above
The telescopes built for the GRUS-3 satellites represent the culmination of Nikon's decades-long expertise in applied optics and precision engineering. Integrated seamlessly with Axelspace’s proprietary image sensor units, they achieve exceptional resolution and image stability despite the strict size and weight constraints of microsatellites.
Operating from an altitude of 585 km, the GRUS-3 satellites will offer a Ground Sampling Distance (GSD) of 2.2 meters—a level of precision sharp enough to distinguish specific aircraft models parked on airport runways. Furthermore, with a remarkable single-swath width of 28.3 km, a single shot can capture the entirety of Tokyo's 23 core wards at once, combining wide-area coverage with high-resolution imagery.
A 7-Satellite Constellation: "Every Day, Same Place"
The true strength of this project lies in the constellation system formed by launching seven identical satellites simultaneously.
Once all seven GRUS-3 satellites become fully operational, they will be capable of re-imaging the exact same location once every day for regions at latitudes of 25 degrees or higher. This significantly enhanced revisit rate is expected to meet the surging real-time demand for Earth observation data across various sectors, including precision agriculture, forestry monitoring, disaster response, security, and infrastructure management. Notably, the new model includes a 'Coastal Blue' band, which enhances marine observation capabilities by making it easier to track underwater topography and seagrass beds.
Nikon's Space DNA: Inherited from Apollo 15 in 1971
The partnership between Nikon and Axelspace is built on a track record of success. Nikon previously supplied custom optics for the very first GRUS-1 satellite launched in December 2018, as well as four subsequent satellites launched in March 2021.
"Ever since a Nikon camera was carried aboard NASA’s Apollo 15 mission in 1971, our optical technologies have constantly pushed boundaries in the harsh environment of space," said Yasuhiro Ohmura, President and CEO of Nikon. "We are honored to continue our partnership with Axelspace and contribute to the advancement of Earth observation and the broader space industry."
The seven GRUS-3 satellites, powered by Nikon’s optical eyes, are scheduled to lift off in July 2026 or later from Vandenberg Space Force Base in California, carried into orbit by SpaceX's Falcon 9 rocket.
