WKG0184T03Y01 is a high-performance, low-power GNSS multi-mode positioning module. It is
based on the AT6850B-7N22 SoC, which integrates RF front-end, baseband processing, BDS
signal processing engine, and power management.
The module supports:
BDS-2 and BDS-3
B1I and B1C signals
Standalone BeiDou positioning and timing
It features high sensitivity, low power consumption, and cost efficiency.
2. Key Features
Supports BDS-2 / BDS-3 (B1I, B1C)
Supports A-BDS for fast cold start and rapid positioning under weak signal conditions
Cold start sensitivity: -148 dBm
Hot start sensitivity: -156 dBm
Reacquisition sensitivity: -160 dBm
Tracking sensitivity: -162 dBm
Position accuracy: 1.5m (CEP50)
TTFF: ≤23s
Low power consumption (~30mA @5V)
Built-in 18×18×2mm ceramic antenna(customization size available)
Integrated LNA
Fast hot start (<1s) with onboard capacitor
Standard NMEA-0183 output
3. Applications
Vehicle navigation and tracking
Power timing / 4G/5G synchronization
IoT positioning devices
UAV (drones)
Portable devices
4. Assisted GNSS
Supports A-BDS, providing assistance data such as ephemeris, approximate position, and
time. This significantly reduces Time-To-First-Fix (TTFF), even in weak signal environments.
5. Output Protocol
The module outputs data via UART interface using NMEA-0183 protocol.
