April 13, 2023

On April 12th, Gizcoupon reported that Qualcomm and Xiaomi successfully tested the meter-level positioning feature on the Xiaomi 12T Pro smartphone, which is powered by the Snapdragon 8+ Gen 1 mobile platform, in Germany. The meter-level positioning feature significantly improves the smartphone’s location accuracy, providing excellent user experience for map navigation, driving, and other location-based applications.

Xiaomi fully utilized Qualcomm meter-level positioning technology for smartphones and Trimble RTX correction service. Previously, the Xiaomi 11 Pro/Ultra was the first commercial smartphone in China to feature Qualcomm meter-level positioning technology.

Meter-Level Positioning

Meter-level positioning accuracy can improve the user experience of smartphones in many scenarios, such as using ride-hailing apps to provide accurate pickup locations for drivers and passengers, recording outdoor exercise routes for fitness apps, and optimizing lane-level accuracy and providing more map details and precise directions for real-time navigation apps.

Combining Qualcomm’s meter-level positioning technology for smartphones with Trimble RTX correction service has brought extremely high location accuracy to commercial smartphones. Integrating Trimble RTX with Snapdragon mobile platforms can enhance the location accuracy of flagship smartphones and achieve higher precision.

The three parties have conducted high-precision validation tests, including driving tests, in various scenarios, such as suburban roads and urban highways. The test results show that the mobile device can achieve meter-level accuracy with a 95% confidence level.
