Completed TRL 7 (started at 5, targeting 7)
This project is to develop the DSM inter-satellite communication solutions through modeling and simulation. The DSM mission concept for the purpose of modeling and simulation methodology development involves a constellation of 24 small satellites orbiting an icy moon of the planet Saturn around 100 km altitude in 3 planes, as observing nodes for science measurement. The notional communication architecture contains a Relay direct to Earth and constellation observing node inter-satellite links (ISL). A QualNet/STK simulation model of the Relay and constellation ISL optical and RF links is developed for the design and optimization of the link and orbital parameters, as well as the inter-networking protocols. Delay Tolerant Networking (DTN) is utilized in the application layer modeling. End-to-end traffic modeling and simulation is performed to define and validate the notional communication architecture, operation concepts, link design, networking protocol and topology. The use of optical multiple access (OMA) swarm arraying technique for the DSM inter-satellite communication is investigated also.
Qualnet/STK simulator is capable of modeling DSM concept for the ISL communication solutions, from S/C flight system to end-to-end multi-layer data traffic simulation. The results enable the system planner to validate performance and effectiveness of the notional communication architecture, link design and mission operation concepts. Essential for TRL advancement to develop DSM ISL solutions. The modeling and simulation methodology developed in this study is applicable to all DSMs in near earth and deep space such as L1/L2 and Cislunar space.
Optical Multiple Access (OMA) technology is game changing/groundbreaking innovation for DSM constellation. New higher-resolution and precision science missions are possible with this technology. OMA service is very suitable for LunaNet. OMA is next generation swarm optical communication for the payload of launch vehicle.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is a mature technology (TRL 7) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
