Lightweight Inter-Nanosatellite Communications System

To address the Army"s need for novel nanosatellite laser communication systems, Physical Optics Corporation (POC) proposes to develop a new Lightweight Inter-Nanosatellite Communications (LINC) system. This system is based on unique integration of a new optical tracking scheme, with a compact common optical antenna for transmitter and receiver, and novel implementation of smart computer-on-module technology. The innovation in using MEMS mirrors and lightweight telescopes for pointing and tracking will enable the system to achieve extremely low-volume (<431 cm^3), low-mass (<0.5 kg), low-power budget (~8 W), high intersatellite communication rates>2 Gbps, low bit-error-rate<10^-6, and highly accurate tracking to communicate with fore and aft satellites based on a 3-kg SMDC-ONE nanosatellite in a simple 10-20 satellite ring constellation, which directly address the SMDC Responsive Space program requirements. In Phase I, POC will demonstrate LINC feasibility by conducting technical analysis and simulation and initial small-scale proof-of-concept prototype testing. In Phase II, POC plans to further refine the design and develop a reliable, launch-ready system integrated into a nanosatellite bus for initial testing and potential transition to a complete nanosatellite laser communication system.
