The RAC-F1 satellite positioning receiver is a decimeter-level high-precision device designed for the military and defense sector. It features a built-in satellite reception antenna and offers comprehensive positioning capabilities, meeting both industrial-level positioning requirements and personal use needs. In complex environments such as overpasses, tree cover, and interference from building glass curtain walls, it can still maintain stable signal output, ensuring real-time and accurate positioning. The device is primarily used in military positioning, lane-level navigation, autonomous driving, and other related scenarios.   Performance Indicators Frequency Points GPS/QZSS: L1 C/A BDS: B1 B1I B1C GLONASS: L1 GALILEO: E1 Positioning Accuracy External/Internal Static: 1.0/0.2m (2σ) External/Internal Dynamic: 0.6/0.5m (2σ) Velocity Accuracy 0.1m/s Sensitivity Tracking: -165dBm Acquisition: -148dBm TIFF Cold Start Time: Average < 42s Warm Start Time: Average < 5s Hot Start Time: Average < 1s Update Rate 1~10HZ (Optional) Communication Protocol NMEA 0183/UBX Protocol (Optional 4G Communication) Baud Rate 115200bps [Optional: 9600/38400] Physical Characteristics Operating Voltage DC 5.0V (Optional Wide Voltage Range 8~36V) Power Consumption Tracking: 260mA@5V Acquisition: 280mA@5V Function Interface UART/RS485/RS232/CAN Product Dimensions Φ151mm*High 45mm IP Protection Rating IP65 Operating Temperature -30~80℃ Storage Temperature -40~85℃
