New Optical Communication Capabilities Using Nanosatellites

In this paper, the benefits derived from the exploitation of nanosatellites for complex telecommunication missions are presented, along with their limitations, and laser technology is identified as a viable solution to dramatically increase the downlink and crosslink capabilities of such miniature platforms. Then, the critical technological issues concerning the integration of an optical telecom terminal on a nanosatellite platform are discussed, considering the perspective advancements in areas such as power generation, propulsion and attitude control. The incompatibility of laser terminals pointing requirements with the current and perspective nanosatellite attitude stability has been identified as the most critical issue to be addressed in order to implement optical links on nanosatellites. A possible solution is presented at the end of the discussion.
