Tesla-C

Overview

Tesla-C is an Optical Bench targeted at the small satellite market to allow for Direct-to-Earth laser communication links. It enables an increased bandwidth with higher security, at comparable on-board resource constraints. Tesla-C was designed, integrated, tested and qualified for flight in partnership between Nedinsco and TNO.

Tesla-C is part of Thales Alenia Space’s Optel-μ satellite communication terminal for microsatellites. The compact and robust design of Tesla-C enables Low-Earth-Orbit satellites to transmit up to 2 Gbps from a satellite to an optical ground station.
