GRUS‑3 Satellite Capabilities
A Next-Generation Earth Observation Microsatellite
About the GRUS‑3α Demonstrator
The GRUS‑3α satellite serves as a proof-of-concept demonstrator for the GRUS‑3 program. Launched on 23 June 2025 via SpaceX’s Falcon 9 Transporter‑14 mission, GRUS‑3α validated the satellite bus and advanced optical system in orbit. The successful demonstration ensures that the full GRUS‑3 constellation will provide reliable, high-quality Earth observation data once deployed in 2026.
About the GRUS‑3 Satellite
GRUS‑3 is a next-generation Earth-observation microsatellite developed by Axelspace Corporation. It captures high-resolution imagery at 2.2 metres and provides frequent global coverage for environmental monitoring, precision agriculture, disaster response, and infrastructure management. The full constellation is scheduled for launch in 2026.
GRUS‑3 satellites feature multispectral imaging with red edge and near-infrared bands, allowing detailed analysis of land, vegetation, and coastal areas. The constellation’s frequent revisit capabilities (up to 3 days) make it ideal for monitoring rapidly changing environments and supporting timely decision-making across commercial and government sectors.
2.2 Metre Ground Resolution Imagery
Enables detailed observations for mining, agriculture, infrastructure, and environmental monitoring.
Multispectral Data and Wide Coverage
Includes red edge and near-infrared bands for advanced land and vegetation analysis.
Frequent Revisits with Full Constellation
Provides revisit times of up to 3 days, supporting timely monitoring and decision-making.
Key Features and Benefits of GRUS‑3
- Captures high-resolution 2.2 metre optical imagery for precise analysis of Earth's surface, land use, and infrastructure.
- Features multiple spectral bands, including Panchromatic, Coastal Blue, Blue, Green, Red, Red Edge, and Near-Infrared, enabling detailed environmental and agricultural monitoring.
- Sun-synchronous orbit at ~585 km altitude allows global coverage and consistent imaging conditions for reliable time-series analysis.
- Swath width of 28.3 km with maximum capture length of 1,356 km, balancing coverage area and high resolution.
- Frequent revisits (up to 3 days) and multispectral diversity support disaster response, precision agriculture, forest monitoring, and infrastructure management.
