Axelspace is developing the next-generation GRUS-3 constellation to meet growing market demands for flexibility, higher frequency, and interoperability, building on the operational experience of GRUS-1. This paper introduces the GRUS-3 mission, scheduled for a 7-satellite launch in 2026. The constellation aims to achieve daily revisits in mid-latitudes and triple the daily area coverage of GRUS-1. Key features include 2.2m panchromatic resolution, an added Coastal Blue band, and sensor compatibility with Sentinel-2. GRUS-3 will offer flexible data products via the AxelGlobe platform to serve diverse user needs.
