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