WKG0254T06Y01 is a high-performance, low-power multi-GNSS navigation and positioning module. It is based on the AT6850 SoC, an 8th-generation low-power chipset from Zhongke Micro. The chip integrates an RF front-end, digital baseband, multi-constellation signal processing engine, and power management unit, providing high integration and simplified external circuitry.

WKG0254T06Y01 supports GNSS signal reception in the L1 frequency band, including BDS (BeiDou Navigation Satellite System), GPS, GLONASS, and Galileo. It supports both single-constellation and multi-constellation positioning. The module also supports BeiDou-2 and BeiDou-3, enabling standalone BeiDou positioning and timing.

With high sensitivity, low power consumption, and compact design, the module is suitable for applications such as vehicle positioning and navigation, power system timing, 4G/5G communication timing, and IoT positioning devices.
