Description
ATLAS-2 is Astrolight’s second generation SDA compatible low SWaP laser communication terminal designed for space-to-ground and space-to-space links. It is optimized for transmission of large volumes of payload data and low data rate return links, making it ideal for Earth observation data relay and distribution. The terminal can self-calibrate in-orbit, providing actionable data that increases overall link reliability. ATLAS-2 is optimized for operation with Astrolight’s OGS-2.5 optical ground station.
