GRUS 1, 2, 3

GRUS [AXELSPACE]

GRUS is a constellation of three 80 kg Earth observation micro-satellites developed by Axelspace. They are equipped with high-performance optical telescopes, which enable them to take images with 2.5 m ground resolution and over 50 km swath.

GRUS can obtain panchromatic images (having sensitivity in all bands from visible to near infrared and normally expressed in grayscale format) and multi-spectral images (having sensitivity only in a specific band; blue, green, red, red edge and near infrared respectively). The ground resolution is 2.5 m for panchromatic images, 5.0 m for multi-spectral images.

GRUS satellites are equipped with high-performance telescopes with cutting-edge image sensors and the swath of its image spans over 50km to realize efficient covering of the entire globe. By launching many GRUS satellites, it enables to update every information around the globe every day, and to apply those data to various industries including agriculture, forestry, fishery, mapping, GIS and disaster monitoring.

The three first-generation GRUS satellites will be launched in 2017, with more satellites planned to follow.
