Description

The Department of Defense (DOD) is seeking proposals for the development of a subminiature digital pitot-static sensor (SDPSS) as part of their Small Business Innovation Research (SBIR) program. The objective is to improve GPS-denied navigation on small unmanned aircraft systems (UASs). The current air-data systems used in aircraft have limitations that create integration challenges, especially for small UASs. The Navy is looking for a new class of digital pitot-static sensors that can overcome these challenges. The sensor should be able to fit within a cylindrical volume of 0.25 inches in diameter and 5 inches long, and contain all necessary readout electronics. It should also provide accurate pressure altitude and indicated airspeed measurements, as well as outside air temperature measurements. The sensor should have a bidirectional digital serial interface and support multiple addressable sensors on the same bus. It should also have built-in self-test capabilities and non-volatile storage for calibration tables and operating parameters. The development will be conducted in two phases, with the option for further refinement and validation in Phase II. The ultimate goal is to transition the technology into various unmanned aviation programs within the DoD and potentially the commercial sector.

DOD SBIR 24.4 Annual - Multilayer Waveguide Optical Gyroscope
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the development of a high-end tactical miniature optical waveguide gyroscope for future U.S. Army missions. The current inertial navigation systems used by the Army are large and expensive, and smaller alternatives such as Micro-Electro-Mechanical (MEMS)-based sensors do not meet the Army's requirements for cost, accuracy, stability, and survivability. The goal is to develop a low-cost and lightweight 6-axis Inertial Measurement Unit (IMU) with high-tactical performance. The desired performance includes a gyro bias stability of 0.2 degrees/hour, scale factor error less than 50 ppm, and angular random walk less than 0.05 degree/root-hour. The gyroscope should also have a high bandwidth, high dynamic range, and low sensitivity to extreme shock and vibration environments. The solicitation focuses on the feasibility of new optical waveguide gyroscope technologies, such as the integrated Silicon waveguide Optical Gyroscope (iSOG). The Phase I of the project involves proving the feasibility of a multi-level waveguide optical sensor coil, while Phase II focuses on designing and delivering a prototype waveguide optical gyroscope. The final phase aims to develop an Inertial Sensor Assembly (ISA) consisting of three gyros and three accelerometers. The technology has potential applications in commercial IMUs and military autonomous modular payloads. The project is open for proposals until March 31, 2025.

DOD SBIR 24.4 Annual - Autonomous Optical Sensors
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic of "Autonomous Optical Sensors" as part of their SBIR program. The objective of this project is to develop a portable optical sensor that can capture high-quality real-time imagery data during missile tests. The sensor will be positioned near a missile launcher or target to analyze the terminal phase of the flight in remote locations where proper test infrastructure is unavailable. The Autonomous Optical Sensor (AOS) system will incorporate high-speed imaging cameras with advanced artificial intelligence and machine learning capabilities. The sensor will operate autonomously for an extended period with either a battery or renewable energy source and wirelessly receive setup and calibration data from a centralized command center. In Phase I, the awardee will research and define an integrated AOS configuration that includes various types of optical sensors and develop an AI framework to manage the system. Phase II will involve creating a prototype of the AOS and refining the integrated system design for optimal performance. The potential impacts of this technology include collecting real-time imagery for air traffic management at airports or surveillance of sensitive areas. It can help track flights, assist in airspace coordination, and alert operators of potential safety or security concerns. The project duration is not specified, but the solicitation is open until March 31, 2025. For more information and to submit a proposal, visit the DOD SBIR website.

Department of Defense
The Department of Defense (DOD) is seeking proposals for the development of an Unmanned Aerial Systems (UAS) Passive Detection, Tracking, and Identification System for Ground Vehicles. The goal of this Army Small Business Innovative Research (SBIR) topic is to develop a passive sensor system capable of detecting, tracking, and identifying single and multiple drones threatening ground vehicles. The system should have a range of up to 2km and provide full hemispherical coverage. It should also include a soldier user interface control panel and the ability to alert at least one operator. The system should be able to operate in wooded/dense environments or large metropolitan areas and be installable on tactical and combat ground vehicles, including Army watercraft. In Phase I, the technical feasibility of passive sensors for drone detection will be determined through computer simulations. The possibility of using passive electromagnetic acoustic, optical, and other innovative sensing for processing multiple drone signatures will be demonstrated. The classification of drone signatures using these passive sensor systems will also be explored. In Phase II, the solution to achieve the capabilities outlined in Phase I will be developed. Optimum materials for the development of passive low-power consumption sensors for UAS detection, tracking, and identification will be identified. Principles of building networks of passive sensors that utilize fast processing capabilities will be developed, along with learning algorithms for drone identification. The system will be evaluated for compliance with the GVSC owned vehicle base kit in the GVSC Vehicle Protection Integration Lab (VPIL). A prototype system will be delivered to GVSC for evaluation and demonstration. Phase III will focus on expanding the capabilities of the solution to simulate different environments and conditions, demonstrating its applicability for municipal security, law enforcement, and commercial vehicles.

DOD SBIR 24.4 Annual - Lightweight Longwave Bolometer Sensor Components
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic "Lightweight Longwave Bolometer Sensor Components" as part of the SBIR program. The objective of this topic is to develop components that enable low size, weight, and power (SWAP) thermal bolometer-type longwave thermal sensor payloads. These components should have equal or better performance than current commercial offerings while driving down SWAP. The components of interest include lens, focal plane, and readout and processing embedded hardware. The components should be ready for integration into a camera module by the end of Phase II. Thermal longwave infrared (LWIR) capabilities are crucial for many Army applications, especially for small Unmanned Aircraft Systems (UAS). However, the size, power, and weight constraints often limit the performance of these sensors. This topic aims to develop components that reduce the weight of thermal payloads while increasing their capabilities and keeping unit costs low. The project will have a Phase I and Phase II, with Phase I proposals accepting a cost of up to $250,000 for a 6-month period of performance. During Phase I, firms should design a proposed component with stakeholder input, analyze the SWAP-C impact of the component, and discuss how it will support the objective sensor payload. Phase II will involve completing the component design, fabricating, testing, and characterizing the component for integration into a lightweight sensor payload. Firms will also refine the design, define relevant interfaces, and lay out a high-level plan for integration. The potential applications of this research include smartphone camera augmentation, UAV camera augmentation, home security systems, and climate tech development. The project references academic research on bolometer manufacturing methods and the efficacy of leveraging colloidal quantum dots (QDs) for IR light sensing. Military contractors have also contributed to the research in the LWIR sensor and bolometer manufacturing spaces.
