RAC-W101

The RAC-W101 is a single-frequency high-precision positioning module that offers comprehensive high-precision positioning capabilities with dynamic accuracy of less than 2.5 meters. It meets the strict requirements of industrial-grade positioning as well as personal usage needs. The product does not require a differential station or use L2 or B3 precise codes. Unlike traditional high-precision satellite positioning technologies, our solution eliminates the reliance on differential technology, significantly reducing costs. It is primarily used in vehicle pre-installation, TBOX, and domain controller integration scenarios.   Performance Indicators Frequency Points GPS/QZSS: L1 C/A BDS: B1 B1I B1C GLONASS: L1 GALILEO: E1 Positioning Accuracy <2.5m CEP Velocity Accuracy 0.1m/s CEP Sensitivity Tracking: -167dBm Acquisition: -160dBm Cold Start: -148dBm Hot Start: -159dBm TIFF Cold Start Time: Average≤30s Warm Start Time: Average<5s Hot Start Time: Average <2s Time Pulse 1s Update Rate 1~10Hz (Optional) PPS 100ms (1pps = 1Hz = 1 time/second) Operational Limitations Altitude: <18,000 m Speed: <500 m/s Acceleration: <4g Output Protocol NMEA 0183/UBX Protocol Baud Rate Default 9600bps Optional [115200/38400bps] (Customizable) Physical Characteristics Operating Voltage DC 3.3V Power Consumption 15mA@3.3V Functional Interface UART Interface Module Dimensions Length: 10.1mm*Width: 9.7mm*Height: 2.5mm Stamp hole package Module Model Description Single positioning chip Operating Temperature -30~85℃ Storage Temperature -40~125℃
