Axelspace Publishes the First Light of GRUS Satellite

AxelGlobe Service Ever Closer to Release

Since the previous announcement, progress continues on the check-out operations of the first GRUS satellite, which was developed by Axelspace Corporation (HQ: Tokyo, Japan; President and CEO: Yuya Nakamura) and was successfully launched on December 27, 2018. As we have confirmed the correct operation of the on-board optical apparatus, we release today the satellite’s first light image.

At the same time we continue our progress toward the release of the AxelGlobe platform, perfecting the constellation’s automatic operation system, working on the consolidation of the image quality and on the web portal. The platform is expected to be released in May.

Below are the details of GRUS’s first light image.
