Problem
Traditional GPS solutions for mobile devices often suffer from accuracy limitations due to signal obstructions and environmental factors, resulting in positioning errors of several meters. This inaccuracy restricts the functionality of location-based applications, particularly in urban environments and indoor spaces. Existing solutions often require expensive infrastructure or complex 3D mapping to achieve higher precision.
Solution
Zephr provides a networked GPS solution that enhances the accuracy of mobile and wearable devices by leveraging a collaborative approach. The technology interconnects satellite measurements across multiple devices, turning each device into a base station that contributes to an ensemble error correction. This method improves location accuracy by 5X-10X, achieving sub-meter precision without relying on external infrastructure. Zephr's software-based solution is delivered as an SDK that can be easily integrated into existing mobile applications to upgrade GPS accuracy. The technology maintains user privacy by minimizing, anonymizing, and protecting user information.
Target Audience
The primary target audience includes developers of mobile applications in augmented reality, gaming, mobility, logistics, delivery services, fitness, and other location-based services, as well as manufacturers of mobile devices and wearables.
