Ground station prototype based on a Ritchey-Chretien telescope with a
coaxial tracking system and commercial mount.

We expect the cost of each ground station in its final configuration to be under $9,000, a figure crucial for duplicability and widespread adoption to allow the construction of a ground station network. The same hardware could be shared among multiple bands,
together with laser downlink users, to spread deployment cost.

CONCLUSION
Building on a number of past missions directed at exploring the use
of VLC on satellites, we have described a highly economical and
space-efficient bidirectional communication system designed for
use on small satellites and as an emergency beacon. Using state-ofthe-art deep learning technology, we are able to implement a system for use in optical communications that is capable of optimizing
itself. This system is shown to have a number of unique advantages
and can be easily commercialized based on present levels of maturity. The flight version of the optical communication payload is
under development and is expected to be integrated into the CubeSat by the end of 2017.
