Mobile Phased Array Antenna using Through the Air Link Optical Component (TALOC) Technology

Silversword Software and Services, LLC (4S) is developing a novel, robust, Free Space Optical (FSO) communications technology entitled Through the Air Link Optical Component (TALOC), applicable for use on military aircraft, both manned and unmanned.  TALOC provides a foundation for measuring range and pose angle between airborne platforms that enables formation of a phase array antenna.  A key use case for phase array is making a highly localized Radio Frequency (RF) link between an Unmanned Airborne Vehicle (UAV) and a ground station.  During Phase 2, we will perform a detailed design and build of a laboratory demonstration system using Commercial Off-the-Shelf (COTS) and custom components.  Demonstration hardware will include optical, electronic and software elements.  Two demonstration stages are envisioned.  For stage 1, the number of test articles is limited and the mechanical structures are at breadboard level.  For stage 2, optics, electronics, and software will be improved based on stage 1 findings.  Stage 2 mechanical structures will move in the direction of aircraft mounting.  Finally, Phase 2.5 work will include production prototype level design for all elements and will lead to phase array system flightworthiness for a relevant environment.  Phase 2 option work includes detailed design review and initiation of production prototype development in preparation for a flight demonstration.    Phase 2 technical objectives are:  Design the antenna element demonstration unit using COTS and custom components  Design a Signal Seed Unit (SSU) surrogate demonstration unit   Acquire demonstration components and test for performance functionality  Design and fabricate stage 1 demonstration optical, electronic, and mechanical components  Write stage 1 demonstration operational software  Test stage 1 Electro-Optic, electronic, and mechanical subsystem assemblies for performance   Conduct stage 1 demonstration  Prioritize risk areas going forward and potential mitigation strategies  Conduct cycle of design, fabrication, component testing, software development, subsystem performance testing and demonstration for stage 2  Perform Technology Readiness Level (TRL) assessment to show TRL 5 or greater   Develop production prototype plans for Phase 2.5.
