GRUS is a next-generation remote-sensing microsatellite, the building block of Axelspace’s Earth observation constellation. Even with its mass of around 100kg, it will enable us to obtain images with 2.5m ground resolution. The first satellite was launched in 2018 followed by many more in the oncoming years, making high-frequency Earth monitoring a reality.
The large constellation of GRUS satellites will update the imagery of the Earth every day, enabling new and more meaningful uses in industries like agriculture, forestry, fishing, mapping, GIS and disaster monitoring.
GRUS will produce images in the panchromatic (grayscale) spectrum with 2.5 m of ground resolution, i.e. the minimum discernible distance between two separate objects. Additionally, it will take multispectral (color) images in the blue, green, red, “red edge” (useful for vegetation analysis) and near-infrared bands. Despite being a microsatellite,
GRUS will use the latest in optical and sensor technology to deliver images spanning more than 50 km in width, allowing for highly efficient coverage of the planet.
GRUS-1B, 1C, 1D and 1E is planning to be launched soon.
