The CubeLCT is a Laser Communication Transmitter for Direct-to-Earth downlinks. It was specifically developed for CubeSat mission in cooperation with DLR-IKN. Its underlying goal was to be the smallest LCT in the world, which could be recently achieved by its successfully held Critical Design Review.
The CubeLCT enables through its small size, weight, and power approach new big data applications for CubeSats, making it a real game changer.
To name some technical benchmarks, the CubeLCT’s size is just 0,3U (approx. 10x10x3cm) by weighing just 350 gram. Thereby it’s able to maintain a sustainable Direct-to-Earth connection to a dedicated ground station over a distance of up to 1,500 km by a data rate of 100 Mbps.
