The Xiaomi 12T Pro supports the QZSS L1 and L5.
QZSS (Quasi-Zenith Satellite System) L1 and L5 are specific frequency bands used by the QZSS system, which is a satellite navigation system developed by Japan.
QZSS is designed to provide accurate positioning and timing information in the Asia-Oceania region, complementing other global navigation satellite systems (GNSS) like GPS (USA), GLONASS (Russia), and Galileo (Europe).
QZSS L1 operates on the same frequency as GPS L1 and other GNSS systems. It provides standard positioning services (SPS) and is used for general navigation and timing purposes.
QZSS L5 is a new frequency band that offers more precise positioning capabilities compared to L1. It is designed for safety-of-life applications and critical infrastructure where high accuracy and reliability are essential.
