About the mission: PIXL-1

PIXL-1 is a joint CubeSat mission of the Institute of Communications and Navigation at the German Aerospace Center (DLR-IKN) and TESAT to test laser communications for CubeSats. Concisely, PIXL-1 is a technology demonstrator for the optical demonstration payload in the framework of the OSIRIS program. Within this project, the DLR-IKN and TESAT develop and manufacture in cooperation highly compact optical communication payloads for small spacecrafts. The commercialization of the optical payload will take place under the designation “CubeLCT”.

At its core, the PIXL-1 mission bases on a 3U cube satellite platform from GomSpace and will take and transfer high-resolution pictures via laser to the ground. For this, several ground stations are at hand worldwide to maintain best quality and highest response times.
