Augmented Reality Navigation Application For Space Habitats

This program will develop an innovative Augmented Reality Navigation (ARNAV) application to help guide astronauts through important tasks within and about space habitats that require navigation and guidance capabilities. Using advanced vision and inertial processing combined with novel Rapidly-exploring Random Tree* (RRT*) algorithms for path planning and Random Finite Set (RFS)-based localization, the novel ARNAV software will provide efficient, optimal, and effective route guidance to human operators by leveraging in-network databases and the environmental data around them. Resulting AR information and visual cues will be relayed to a handheld mobile device with portability to heads up displays (HUDs), and provide key, streamlined, and real-time navigational updates throughout important and mission-critical tasks and procedures. The software architecture will balance provision of relevant and meaningful data with rich AR visualizations, while limiting extensive non-essential feedback, in order to ensure effective, yet practical, operation. Pattern and feature recognition algorithms, including pre-processing delineation routines, 3-D coordinate tracking for feature recognition, utilities for mitigating scene clutter and primary error sources, and the innovative path optimization and localization strategies will be integrated into a prototype ARNAV application. The ARNAV framework will include access to all developed algorithms, database and mapping structures, processing architectures, and a user interface design for AR overlays. Phase I will focus on developing the associated algorithms and ARNAV software application for simulations and performance assessment in representative emulated testing, along with human usability evaluations, to establish accuracy and effectiveness measures for the system.

The ARNAV system will be directly applicable to NASA’s crewed exploration missions. This application will enhance operational and procedural capabilities inside and outside space habitats, with extension to integration with astronaut spacesuits, helmet visors, and existing spacecraft display units. Direct mission applications include the Lunar Gateway, Human Landing System, or Artemis Base Camp.

The ARNAV algorithms apply to commercial and defense systems requiring effective and efficient guidance, particularly within emergency, tactical, or time- and precision-critical situations. Non-NASA applications include navigation for factory or logistics workers, Emergency Medical Technician utilization during triage, and guiding medical industry staff to equipment and patients.

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

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.
