Our Evolution—When GPS Fails
XPHERA's technology has evolved significantly since our early days of using GPS for city navigation. While GPS provided a foundational layer of location awareness, its limitations in precision and environmental context led us to explore more advanced solutions to meet the demands of immersive augmented reality experiences.
This is why XPHERA has built XEarth from the ground up—the Visual Positioning System (VPS) and Geospatial Platform powered by artificial intelligence. Comprising of over 11 billion geospatial data points, XEarth is a visual grid of the entire earth to allow anyone to instantly pinpoint their own location without GPS or internet connection, using just visual cues. We reduce dependency on “the invisible utility” of GPS and IoTs by providing an alternative framework to localize people and objects with sub-foot accuracy (≤ 6 inches) in less than half a second in GPS and internet-denied environments — enabling real-time emergency response, situational awareness, and precise navigation.
XEarth integrate high-precision laser scanning, computer vision (CV), and artificial intelligence to create an advanced Visual Positioning System (VPS). Laser scanning allows us to capture detailed spatial data with millimeter-level accuracy, ensuring that virtual elements align seamlessly with the real-world environment.
The computer vision algorithms we employ process images and video in real-time, recognizing and interpreting environmental features to provide accurate spatial orientation. Artificial intelligence models, trained on large datasets, enhance this system's adaptability by improving object detection, scene understanding, and motion tracking. Since 2021, we have integrated multiple geospatial data pipelines, and have aggregated over 11 billion geospatial data points across the entire earth.
Our technical stack is designed for scalability and reliability, enabling integration into diverse applications—from immersive navigation to tradition top-down maps. By continuously refining our methods and leveraging advancements in CV and AI, we ensure that our technology meets the highest standards for precision and performance.
Our Evolution—When GPS Fails
GPS for Guidance
Global Positioning System (GPS) technology, while widely utilized for navigation, has inherent limitations that affect its accuracy and reliability. Under optimal conditions—such as an unobstructed view of the sky—GPS-enabled devices can achieve accuracy within a 4.9-meter radius. However, this precision significantly diminishes in environments where signal obstruction or reflection occurs.
Urban areas with dense concentrations of tall buildings, often referred to as "urban canyons," pose significant challenges to GPS accuracy. Structures like skyscrapers can block or reflect GPS signals, leading to multipath errors where signals bounce off surfaces before reaching the receiver. This phenomenon causes the receiver to calculate positions based on both direct and reflected signals, resulting in inaccuracies. Additionally, materials such as metal and concrete exacerbate signal attenuation and reflection, further degrading positional accuracy. Underground subways yield GPS unusable.
