The OpComms Team's longest successful test transmitted a binary signal over a 10km link

Optical Communications is a student-led project aiming to develop the capability to establish high-bandwidth data links over free space. The group began work at the beginning of the 2014-2015 academic year, under the leadership of Thomas Teisberg and Logan Herrera. It was initially formed to investigate the possibility of space-based optical communications, with the intent to participate in the NASA CubeQuest Challenge, a competition for small satellite design. Since its inception, the Optical Communications group has evolved to focus on the establishment of long-distance optical links, with the eventual goal of integrating this technology into a CubeSat form-factor satellite for the purposes of space-based communication. In its first year of existence, the group developed a system involving mechanized altitude/azimuth mounts, an original receiver device consisting of a Fresnel lens and photodetector, and a MATLAB pointing algorithm based on reference point alignment. The group’s final test resulted in the successful establishment of an optical link over 10 kilometers.

The current team leads are Sasha Maldonado and Elizabeth Hillstrom.
