A Bold Leap into the Future of Earth Observation

Japan’s innovative Axelspace Corporation is making waves in the satellite industry with an ambitious plan to launch seven next-generation Earth observation (EO) microsatellites by 2026. This move promises to expand their microsatellite constellation significantly, enhancing global observation capabilities.

Meet the GRUS-3: Revolutionizing Earth Monitoring

The new satellites, dubbed GRUS-3, will elevate Axelspace's capabilities, allowing for broader and more frequent surveillance of our planet. Designed to cater to an array of sectors—from environmental preservation to real estate management—these satellites will meet the surging demand for high-quality EO data.

Building on Success: The GRUS-1 Legacy

Currently, Axelspace operates a successful fleet of five GRUS-1 microsatellites, which provide essential services to over 30 countries. The GRUS-3 initiative is set to enhance this legacy, enabling daily imaging of select locations at the same time and spot under optimal sunlight conditions, thanks to a sun-synchronous orbit positioned at 585 km above Earth.

Massive Data Capture and Advanced Technology

Each GRUS-3 satellite boasts an impressive swath width of 28.3 km, with a capacity to capture up to 2.3 million square kilometers daily across all seven satellites. Featuring a spatial resolution of 2.2 meters, the GRUS-3 isn’t just about capturing stunning images; it also includes cutting-edge sensors for monitoring everything from plant health to coastal ecosystems.

Leadership Vision: Expanding Horizons

Yuya Nakamura, President and CEO of Axelspace, stated, "With the launch of seven GRUS-3 microsatellites, we will observe wider areas more frequently than ever before. This will enhance services for our current customers and allow us to tackle emerging market needs." His vision reflects Axelspace's commitment to redefining EO data utilization.

The Road Ahead: Launch Plans and Technology Verification

The journey toward realizing this grand vision begins with the launch of GRUS-3a, a test microsatellite scheduled for no earlier than June 2025. This initial launch will help validate the performance and functions of the GRUS-3 design across various missions.

Creating a Space-Empowered Society

Founded in 2008, Axelspace operates with two core business strands: AxelLiner, focusing on microsatellites for client missions, and AxelGlobe, which delivers EO data via its proprietary satellite network. Nakamura emphasizes, "By leveraging our unique technology in microsatellite design and operations, we aspire to make space accessible to everyone worldwide."

Grus Constellation: More Than Just a Name

The GRUS series of satellites, each weighing around 100 kg, is not just a technical marvel; it symbolically references the Grus constellation, mirroring how these satellites travel the globe like a flock of cranes—each playing a crucial role in expanding our understanding of Earth.
