2023 Entrepreneurs Challenge Winner Skyline Nav AI: Revolutionizing GPS-Independent Navigation with Computer Vision
NASA sponsored Entrepreneurs Challenge events in 2020, 2021, and 2023 to identify innovative ideas and technologies from small business start-ups with the potential to advance the agency’s science goals. To help leverage external funding sources for the development of innovative technologies of interest to NASA, SMD involved the venture capital community in Entrepreneurs Challenge events. Challenge winners were awarded prize money, and in 2023 the total Entrepreneurs Challenge prize value was $1M. Numerous challenge winners have subsequently received funding from both NASA and external sources (e.g., other government agencies or the venture capital community) to further develop their technologies.
Skyline Nav AI, a winner of the 2023 NASA Entrepreneurs Challenge, is pioneering GPS-independent navigation by leveraging cutting-edge computer vision models, artificial intelligence (AI), and edge computing.
Skyline Nav AI’s flagship technology offers precise, real-time geolocation without the need for GPS, Wi-Fi, or cellular networks. The system utilizes machine learning algorithms to analyze terrain and skyline features and match them with preloaded reference datasets, providing up to centimeter-level accuracy in GPS-denied environments. This capability could enable operations in areas where GPS signals are absent, blocked, degraded, spoofed, or jammed, including urban canyons, mountainous regions, and the Moon.
Skyline Nav AI’s flagship technology at work in New York to provide precise location by matching the detected skyline with a reference data set. The red line shows detection by Skyline Nav AI technology, the green line marks the true location in the reference satellite dataset, and the orange line represents the matched location (i.e., the location extracted from the satellite dataset using Skyline Nav AI algorithms). Skyline Nav’s visual navigation technology can deliver accuracy up to five meters, 95% of the time. The AI-powered visual positioning models continuously improve geolocation precision through pixel-level analysis and semantic segmentation of real-time images, offering high reliability without the need for GPS.
In addition to its visual-based AI, Skyline Nav AI’s software is optimized for edge computing, ensuring that all processing occurs locally on the user’s device. This design enables low-latency, real-time decision-making without constant satellite or cloud-based connectivity, making it ideal for disconnected environments such as combat zones or space missions.
Furthermore, Skyline Nav AI’s technology can be integrated with various sensors, including inertial measurement units (IMUs), lidar, and radar, to further enhance positioning accuracy. The combination of visual navigation and sensor fusion can enable centimeter-level accuracy, making the technology potentially useful for autonomous vehicles, drones, and robotics operating in environments where GPS is unreliable.
“Skyline Nav AI aims to provide the world with an accurate, resilient alternative to GPS,” says Kanwar Singh, CEO of Skyline Nav AI. “Our technology empowers users to navigate confidently in even the most challenging environments, and our recent recognition by NASA and other partners demonstrates the value of our innovative approach to autonomous navigation.”
Skyline Nav AI continues to expand its influence through partnerships with organizations such as NASA, the U.S. Department of Defense, and the commercial market. Recent collaborations include projects with MIT, Draper Labs, and AFRL (Air Force Research Laboratory), as well as winning the MOVE America 2024 Pitch competition and being a finalist in SXSW 2024.

NASA Stennis Celebrates Key Testing, Operations Milestones in 2024 NASA Exhibit Puts Visitors in Test Conductor Seat NASA Stennis Hosts Mississippi Kween Gator Speaks
Gator SpeaksNASA/Stennis This time of year is one Gator enjoys. The ending of one year and beginning of another provides the opportunity to reflect, reset, and refocus.
This is true at NASA Stennis, a place that powers space dreams, or for someone who enjoys staying up to date with all the happenings around NASA Stennis – you!
In 2024, Gator witnessed the legacy of excellence continue at the south Mississippi NASA center. There were milestones reached with RS-25 engine testing and preparations for testing NASA’s new exploration upper stage for future Artemis missions, the center continued to fuel the space market with its support of commercial companies at the E Test Complex, and it was announced the historic in-space payload mission for the NASA Stennis Autonomous Systems Laboratory team would continue.
Another bright spot at NASA Stennis is range operations. The partnership between NASA Stennis and Skydweller Aero represents the first big step in this area. In 2024, NASA Stennis entered into an agreement with Skydweller Aero for the company to operate its solar-powered autonomous aircraft in the site’s restricted airspace.
It marks the first agreement between NASA Stennis and a commercial company to use the center’s unique capabilities to support testing and operation of uncrewed systems.
The future is indeed bright. The new year is like the NASA Stennis buffer zone. The 125,000-plus acre buffer zone enables many opportunities for site achievement and advancement, much like a new year does.
We all can make 2025 the best year to date by building on what we have accomplished and setting bold, new goals.
Here is to 2025 – a year of focus, ambition, and collaboration. Together, we can turn our goals into achievements and make this year one of our best yet.
Happy New Year!

A model of NASA’s SLS (Space Launch System) rocket is part of the holiday display in the Mississippi Governor’s Mansion in Jackson, the official residence of state Gov. Tate Reeves. The model symbolizes the longtime relationship and shared history between the state of Mississippi and NASA’s Stennis Space Center near Bay St. Louis, Mississippi, the nation’s largest rocket propulsion test site. Built in the 1960s, NASA Stennis tested Apollo rocket stages that carried humans to the Moon and every main engine that helped launch 135 space shuttle missions. It now is testing engines and systems for NASA’s Artemis missions and operates as a powerful aerospace and technology hub for the region and state. “We are grateful for our ongoing relationship with the state of Mississippi,” NASA Stennis Director John Bailey said. “We appreciate every opportunity to highlight the role NASA Stennis and the state play in helping to power the nation’s human space exploration program. We look forward to 2025 and continuing our work to test engines and systems that will help launch Artemis missions back to the Moon and beyond.” NASA Stennis/Troy Frisbie NASA Stennis Director Hosts Java with John
NASA Stennis Director John Bailey hosts a Java with John session on Dec. 10 with employees representing the Office of the Chief Financial Officer, Office of STEM Engagement, Office of Diversity and Equal Opportunity, Office of the Chief Human Capital Officer, and the center’s Autonomous Systems Laboratory team. Java with John is an employee-led discussion in a casual environment aimed at fostering a culture in which employees are welcome to share what matters most to them at work.
