The Department of Defense (DOD) is seeking proposals for the Small Business Innovation Research (SBIR) Phase I program. The specific topic of the solicitation is "High-Speed, Cross-Domain Data Transfer" and is being solicited by the Navy. The objective of the research is to identify, develop, and demonstrate technologies that enable high-speed, wireless data transfer across the air-sea interface via unmanned platform teaming. The current challenge is to wirelessly transfer sensor data from advanced sensor payloads on unmanned underwater vehicles across the air-sea interface for analysis in a timely manner. The current state-of-the-art uses acoustic methods with low-data bandwidth, and existing techniques like buoys are not effective for dynamic missions. The goal is to develop a methodology that leverages multi-spectrum technology (acoustic, radio, and optical) and unmanned teaming to achieve high-data rates (greater or equal to 10 Mb/s) across the air-sea interface. The Phase I effort involves developing a methodology that incorporates unmanned platform teaming and diverse communication technologies, including initial modeling and proof-of-concept. Phase II focuses on demonstrating the methodology in a relevant environment, while Phase III involves commercialization and dual-use applications. The technology has potential applications in the private sector, such as oil and gas exploration, harbor operations, and infrastructure inspections. The project duration is not specified, and funding specifics can be found on the solicitation agency's website.
