01
Next-Generation GNSS SoC with Full-Constellation Support
The K601 module is powered by the advanced TC1720, a proprietary RF and baseband integrated GNSS positioning chip designed for reliable, high-performance computing. It tracks multi-frequency signals across all major global satellite constellations, including GPS, BDS, GLONASS, Galileo, QZSS, and NAVIC. Featuring a 128-channel engine, the module ensures rapid signal acquisition and robust tracking capabilities across demanding operational conditions.
02
Superior Navigation Performance
Featuring a proprietary positioning algorithm and on-chip sensor fusion, the K601 combines GNSS and IMU data for reliable positioning in challenging environments such as urban canyons. Adaptive interference detection and mitigation further ensure stable operation under complex electro magnetic conditions.
03
Ultra-Compact Footprint & Low Power Consumption
The K601 adopts a compact 12mm × 16mm LGA 24-pin package, ideal for space- and power-sensitive applications. With only 100mW power consumption during tracking, it is well suited for intelligent driving, unmanned systems and handheld devices.
