Summary

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.

Description

OUSD (R&E) CRITICAL TECHNOLOGY AREA(S): FutureG;Integrated Network Systems-of-Systems; Trusted AI and Autonomy

 

OBJECTIVE: Identify, develop, and demonstrate technologies that enable high-speed, wireless data transfer across the air-sea interface via unmanned platform teaming.

 

DESCRIPTION: The problem: Advanced sensor payloads are being developed for unmanned underwater vehicles to detect and identify subsea threats. The challenge is to wirelessly transfer the sensor data from these payloads, in a timely manner, across the air-sea interface for analysis.

 

The current state-of-the-art: Generally, modern underwater communication links use acoustic methods whose biggest shortcoming is low-data bandwidth (< 1 Mbps) [Refs 1, 2]. Currently, high-speed wireless data transfer from underwater platforms requires the platform to surface and establish a radio link or be physically recovered by a crewed platform, interrupting the mission, and revealing the platform’s location. Additionally, the time it takes to acquire and process the data may render the information obsolete, reducing its effectiveness for decision making.

 

Techniques to assist the passage of data through the sea surface, like buoys, are typically passively drifting or moored to a single location, reducing their effectiveness in supporting dynamic missions that cover large areas. With the advancement of autonomous systems, teaming between air, surface, and subsea unmanned platforms combined with new communication techniques, such as those that leverage multiple parts of the frequency spectrum [Refs 3–5] (i.e., acoustic, or optical frequencies underwater, and RF frequencies above water), have the potential to enable cross-domain command and control, and high-speed data transfer. High-speed, underwater, optical communication links have been demonstrated in the lab [Refs 6, 7], but their applicability to a relevant environment is not proven. This STTR topic aims to develop and demonstrate a methodology that leverages multi-spectrum technology (i.e., acoustic, radio, and optical)—paired with unmanned teaming—to enable high-speed communications across the air-sea interface in a wide range of water types. Data rates across the air-sea interface of greater or equal to 10 Mb/s are required, and the size, weight, and power (SWaP) of the components should be compatible with unmanned platforms.

 

PHASE I: Develop a methodology that incorporates unmanned platform teaming (i.e., air, surface, and underwater) with diverse communication technologies (i.e., acoustic, radio, and optical) to achieve high-data rates across the air-sea boundary. The methodology should include initial modeling of the communication links, and of relevant unmanned platform teaming behaviors to serve as a proof-of-concept for the proposed solution. Metrics such as communication range, throughput, persistence, and reliability should be investigated. Specific sensor technology and unmanned platforms should be identified, and the intended operating environment conditions specified. References to relevant work are encouraged and awardees may include an initial demonstration of communication technologies—and/or unmanned teaming—in simulated or relevant environments to further reinforce the legitimacy of the proposed solution. The Phase I effort will include prototype plans to be developed under Phase II.

 

PHASE II: Demonstrate the methodology developed in Phase I in a relevant environment. Sensors identified in Phase I should be produced or procured, and integrated into the unmanned platforms, also identified in Phase I. The methodology should be tested in a simulated environment before being deployed in a relevant environment. Unmanned teaming behavior should be developed to support the methodology identified in Phase I. Data from lab and field testing should be used to validate the models within the proposed solution.

 

PHASE III DUAL USE APPLICATIONS: Develop commercialization of the device, manufacturing methods, and finalize device form factor and capabilities. Evaluate market potential for military and civilian applications and assess required infrastructure for continued technology readiness level (TRL) and manufacturing readiness level (MRL) development.

 

Persistent situational awareness of the underwater domain is applicable for several private sector applications. Oil and gas can leverage this technology to survey challenging drill sites and inspect underwater infrastructure. Harbor operations, such as hull inspection, security, and infrastructure inspections would benefit as well. Unmanned teaming has the potential to reduce the need for, and risk to, crewed operations. Pairing this with advanced laser sensors will enable higher quality inspections for better decision making.

The Department of Defense (DOD) is seeking proposals for the topic of "Advanced Enabling High-Speed Technologies" in their SBIR 24.4 Annual solicitation. The Defense Advanced Research Projects Agency (DARPA) is specifically interested in technologies related to additive manufacturing techniques, materials, propulsion combined cycles, and hot structures. They are also looking for advancements in the understanding and characterization of novel fluid dynamics that enhance propulsion performance. The objective is to achieve coherence between a cooperating set of commodity devices, resulting in increased thrust to weight, fuel efficiencies, and propellant mass fractions. This solicitation is open for Phase II proposals only, and Phase I proposals will not be accepted or reviewed. Phase II will involve designing and evaluating enabling technologies at the system and subsystem level, as well as advancing modeling and simulation tools. Physical hardware proposals should include development, installation, integration, demonstration, and/or test and evaluation of the proposed prototype system. Software or advanced tool development proposals should have a development approach anchored in the physics of the problem and ways to validate the software against existing test data. The Phase II effort consists of a base period of 12 months and an option period of 12 months. Phase III of this project will focus on transition and commercialization of the developed technologies. The proposer is required to obtain funding from private sector or non-SBIR Government sources to develop the prototype software into a viable product or non-R&D service for sale in military or private sector markets. The technologies developed under this topic will have applications in both commercial and military sectors, including commercial transportation, high-speed delivery, and responsiveness to fluidic environments. For more information and to submit proposals, interested parties can visit the DOD SBIR 24.4 Annual topic page on the SBIR website (https://www.sbir.gov/node/2492697).
