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’s LEXI Will Provide X-Ray Vision of Earth’s Magnetosphere
A NASA X-ray imager is heading to the Moon as part of NASA’s Artemis campaign, where it will capture the first global images of the magnetic field that shields Earth from solar radiation.
The Lunar Environment Heliospheric X-ray Imager, or LEXI, instrument is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center in Florida no earlier than mid-January, with Firefly Aerospace’s Blue Ghost Lander. The instrument will support NASA’s goal to understand how our home planet responds to space weather, the conditions in space driven by the Sun.
NASA’s next mission to the Moon will carry an instrument called LEXI (the Lunar Environment Heliospheric X-ray Imager), which will provide the first-ever global view of the magnetic environment that shields Earth from solar radiation. This video can be freely shared and downloaded at https://svs.gsfc.nasa.gov/14739.
Credits: NASA’s Goddard Space Flight Center Once the dust clears from its lunar landing, LEXI will power on, warm up, and direct its focus back toward Earth. For six days, it will collect images of the X-rays emanating from the edges of our planet’s vast magnetosphere. This comprehensive view could illustrate how this protective boundary responds to space weather and other cosmic forces, as well as how it can open to allow streams of charged solar particles in, creating aurora and potentially damaging infrastructure.
“We’re trying to get this big picture of Earth’s space environment,” said Brian Walsh, a space physicist at Boston University and LEXI’s principal investigator. “A lot of physics can be esoteric or difficult to follow without years of specific training, but this will be science that you can see.”
What LEXI will see is the low-energy X-rays that form when a stream of particles from the Sun, called the solar wind, slams into Earth’s magnetic field. This happens at the edge of the magnetosphere, called the magnetopause. Researchers have recently been able to detect these X-rays in a patchwork of observations from other satellites and instruments. From the vantage point of the Moon, however, the whole magnetopause will be in LEXI’s field of view.
In this visualization, the LEXI instrument is shown onboard Firefly Aerospace’s Blue Ghost Mission 1, which will deliver 10 Commercial Lunar Payload Services (CLPS) payloads to the Moon. Firefly Aerospace The team back on Earth will be working around the clock to track how the magnetosphere expands, contracts, and changes shape in response to the strength of the solar wind.
“We expect to see the magnetosphere breathing out and breathing in, for the first time,” said Hyunju Connor, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the NASA lead for LEXI. “When the solar wind is very strong, the magnetosphere will shrink and push backward toward Earth, and then expand when the solar wind weakens.”
The LEXI instrument will also be poised to capture magnetic reconnection, which is when the magnetosphere’s field lines merge with those in the solar wind and release energetic particles that rain down on Earth’s poles. This could help researchers answer lingering questions about these events, including whether they happen at multiple sites simultaneously, whether they occur steadily or in bursts, and more.
These solar particles streaming into Earth’s atmosphere can cause brilliant auroras, but they can also damage satellites orbiting the planet or interfere with power grids on the ground.
“We want to understand how nature behaves,” Connor said, “and by understanding this we can help protect our infrastructure in space.”
The LEXI team packs the instrument at Boston University. Michael Spencer/Boston University The CLPS delivery won’t be LEXI’s first trip to space. A team at Goddard, including Walsh, built the instrument (then called STORM) to test technology to detect low-energy X-rays over a wide field of view. In 2012, STORM launched into space on a sounding rocket, collected X-ray images, and then fell back to Earth.
It ended up in a display case at Goddard, where it sat for a decade. When NASA put out a call for CLPS projects that could be done quickly and with a limited budget, Walsh thought of the instrument and the potential for what it could see from the lunar surface.
“We’d break the glass — not literally — but remove it, restore it, and refurbish it, and that would allow us to look back and get this global picture that we’ve never had before,” he said. Some old optics and other components were replaced, but the instrument was overall in good shape and is now ready to fly again. “There’s a lot of really rich science we can get from this.”
Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. NASA Goddard is a lead science collaborator on LEXI. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development of seven of the 10 CLPS payloads carried on Firefly’s Blue Ghost lunar lander, including LEXI.
