WKG0254T00Y01 supports multiple satellite navigation systems, including China's BDS (BeiDou Navigation Satellite System), the U.S. GPS, Russia's GLONASS, Japan's QZSS, and SBAS (WAAS, EGNOS, GAGAN, MSAS). With 32 tracking channels, it can simultaneously receive GNSS signals from up to six satellite systems and enable multi-constellation positioning and navigation.
Featuring high sensitivity, low power consumption, and cost-effectiveness, WKG0254T00Y01 is ideal for applications such as vehicle navigation, handheld positioning devices, and automotive rearview mirrors.
l WKG0254T00Y01 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: 2.5m (CEP50)
l TTFF: ≤32s
l Low power consumption (~30mA @5V)
l Built-in 25×25×4mm ceramic antenna(customization size available)
l Integrated LNA
l Fast hot start (<1s) with onboard capacitor
l Standard NMEA-0183 output
Applications
l Automotive rearview mirror systems
l Handheld positioning devices
l Marine and vehicle navigation
l Tracking and location-based services
l Portable electronic devices
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.
The module outputs data via UART interface using NMEA-0183 protocol.
