GNSS / BeiDou Modules

18×18mm Compact GNSS Module WKG0184T06Y01

WKG0184T06Y01 is a high-performance, low-power multi-GNSS navigation and positioning module. It is equipped with the AT6850-7N76 SoC, the 8th-generation low-power chipset from Zhongke Micro. This chipset integrates an RF front-end, digital baseband, multi-constellation signal processing engine, and power management unit, resulting in high integration and simplified external circuitry.

Product Overview

WKG0184T06Y01 is a high-performance, low-power multi-GNSS navigation and positioning module. It is equipped with the AT6850-7N76 SoC, the 8th-generation low-power chipset from Zhongke Micro. This chipset integrates an RF front-end, digital baseband, multi-constellation signal processing engine, and power management unit, resulting in high integration and simplified external circuitry.

 

WKG0184T06Y01 supports GNSS signal reception in the L1 frequency band, including China’s BDS (BeiDou Navigation Satellite System), the U.S. GPS, Russia’s GLONASS, and the EU’s Galileo. It enables both single-system positioning and multi-constellation positioning. The module supports BeiDou-2 and BeiDou-3, and allows standalone BeiDou positioning and timing.

 

With advantages such as high sensitivity, low power consumption, and cost-effectiveness, the WKG0184T06Y01 is well suited for applications including vehicle positioning and navigation, power system timing, 4G/5G communication timing, and IoT positioning devices.


Key Features


l WKG0184T06Y01 supports both single-constellation (BDS or GPS) and multi-constellation positioning. It is configurable to operate with any single GNSS system or in combined modes, including BDS, GPS, GLONASS, and Galileo.

l Supports A-GNSS for fast cold start and rapid positioning under weak signal conditions

l Cold start sensitivity: -148 dBm

l Hot start sensitivity: -156 dBm

l Reacquisition sensitivity: -160 dBm

l Tracking sensitivity: -162 dBm

l Position accuracy: 1.5m (CEP50)

l TTFF: ≤23s

l Low power consumption (~30mA @5V)

l Built-in 18×18×2mm ceramic antenna(customization size available)

l Integrated LNA

l Fast hot start (<1s) with onboard capacitor

l Standard NMEA-0183 output


Applications


l Vehicle navigation and tracking

l Power timing / 4G/5G synchronization

l IoT positioning devices

l UAV (drones)

l Portable devices


Assisted GNSS


Supports A-GNSS, providing assistance data such as ephemeris, approximate position, and time.

This significantly reduces Time-To-First-Fix (TTFF), even in weak signal environments.


Output Protocol


The module outputs data via UART interface using NMEA-0183 protocol.
