Blink Astro, LLC proposes a Phase II SBIR development effort that includes prototyping the ION-DTN protocol on our Phase I downselected microcontroller, integrated radio design, and a final demo of 3 ION-DTN nodes simulating a real-world scenario. Creation of a market strategy and supporting marketing collateral materials will also be developed for the end product as it is being advanced from TRL 3 to TRL 4 at the conclusion of effort. Potential NASA Applications (Limit 1500 characters, approximately 150 words) This solution has immediate applicability in enabling deep space communication or swarm constellation science missions. As NASA begins to more broadly adopt small satellites, the need for a small form factor, lower power, delay and disruption tolerant radio becomes paramount, especially as more novel mission concepts outside of Low Earth Orbit emerge. Blinks ION-DTN Radio offers a cost-effective, turnkey solution to meeting DTN demands for future NASA missions and enables small satellite missions of greater scale and scientific return. Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words) Non-NASA commercial applications for the Blink® ION-DTN Radio range from real-time aircraft tracking to commercial LEO satellite constellations. Of particular interest to Blink®, is the near-term applicability of the ION-DTN Radio with its LEO satellite constellation for IoT connectivity.
