Also known as: Universal Positioning System, UPS
A hardware-free GPS alternative that tracks movement anywhere on Earth using device-embedded sensors and neural networks.
GPS fails in 90 percent of environments where humans and objects spend time, including indoors, underground, dense urban areas, forests, and remote regions. Alternative beacon systems are prohibitively expensive to install and maintain.

Juxta is developing the Universal Positioning System (UPS), a revolutionary GPS alternative designed to track people and objects anywhere on Earth without requiring new external hardware. Unlike traditional GPS systems that rely on satellites, beacons, or infrastructure installations, Juxta leverages sensors already embedded in smartphones and devices—such as accelerometers, gyroscopes, and inertial measurement units (IMUs)—to provide precise location tracking in environments where GPS fails.
Conventional GPS technology has fundamental limitations that make it unsuitable for real-world tracking needs. Over 90 percent of human and object movement occurs indoors or in areas where GPS signals cannot penetrate, including warehouses, hospitals, underground facilities, dense urban environments, forests, and remote regions. GPS signals are blocked by thick walls, cannot function underground, and fail in areas with weak or jammed signals. Additionally, alternative beacon-based systems like Bluetooth Low Energy (BLE) or Ultra-Wideband (UWB) require expensive infrastructure, costing upwards of $250,000 per site to install and maintain. These limitations leave critical blind spots in location monitoring across logistics, defense, healthcare, and emergency response sectors.

Juxta's approach uses neural networks pre-trained on a room's layout to understand how a device's IMU measurements correspond to real-world location updates. The system generates synthetic sensor data through 3D simulations of physical spaces, creating a cross-reference between simulated data and real-life sensor measurements. When millions of people or objects move through a space, they gather sensor data that the system uses to build confidence models. If a device has specific sensor measurements (A, B, C) at a particular location, the system can predict that other devices with identical measurements will be at the same location. This synthetic fingerprinting approach enables rapid deployment without requiring manual data collection in each new space.

Juxta claims to achieve approximately half-meter accuracy anywhere on Earth—indoors, outdoors, underground, or in any environment where humans or objects travel. The technology works in GPS-denied spaces including tunnels, battlefields, dense urban areas with skyscrapers, and underwater environments. Because the system relies on sensors already present in devices rather than external infrastructure, it offers truly universal coverage without the need for satellites thousands of miles above Earth or beacons installed throughout facilities.

The platform serves multiple industries and use cases. In logistics and warehousing, Juxta enables real-time asset tracking and inventory management without infrastructure investment. Healthcare facilities can monitor patient and equipment location in hospitals where GPS fails. Defense and military applications benefit from unjammable tracking in contested environments. Emergency response teams can coordinate operations in underground or GPS-denied spaces. The technology also supports consumer applications, allowing businesses to instantly map areas and make them location-aware within minutes.

Juxta operates on a software-based model requiring no new hardware deployment. The system is remotely deployable, cost-effective compared to traditional beacon systems, and functions offline. The company targets businesses, defense agencies, and consumers seeking reliable location tracking in environments where GPS is inadequate. The hardware-free approach eliminates the capital expenditure barriers associated with beacon infrastructure, making location awareness accessible to organizations of all sizes.

Juxta's founder envisions expanding location monitoring to cover ten times the space that GPS currently covers, effectively making visible the 90 percent of human and object movement that remains invisible to existing systems. The company aims to monitor location in every indoor and outdoor space where humans and objects travel, positioning UPS as a fundamental replacement for GPS with significantly broader applicability.
