The for Raspberry Pi expansion board with GNSS (Global Navigation Satellite System) function supports GPS, Beidou (BDS) and QZSS multiple satellite systems, and has the advantages of fast positioning, accurate positioning and low power consumption. Take me with you, and your for Raspberry Pi will be able to easily achieve global positioning. Based on for Raspberry Pi 40PIN GPIO interface design, suitable for Raspberry Pi series motherboards, for Jetson Nano Supports GPS, Beidou (BDS) and QZSS multiple satellite systems Supports EASY self-generated orbit prediction function for fast positioning Supports AlwaysLocate function for intelligent control of periodic mode Supports DGPS, SBAS (WAAS/EGNOS/MSAS/GAGAN) Supports serial communication baud rate range: 4800-115200bps (default 9600bps) [GNSS parameters] Signal frequency band: GPS L1 (1575.42Mhz), BD2 B1 (1561.098MHz) Number of channels: 33 tracking channels, 99 acquisition channels and 210 PRN channels C/A code SBA: WAAS, EGNOS, MSAS, GAGAN Horizontal positioning accuracy: Autonomous positioning: Less than 2.5mCEP Time to first fix @ -130dBm (EASY function turned on): Cold start: Less than 15s Warm start: Less than 5s Hot start: Less than 1s Sensitivity: Acquisition: -148dBm Tracking: -163dBm Recapture: -160dBm Dynamic performance: Altitude (max): 18000m Speed (max): 515m/s Acceleration (max): 4G [My other parameters] Communication interface:UART Serial port baud rate:4800-115200bps (default 9600bps) Update rate:1Hz (default), 10Hz (max) Communication protocol:NMEA 0183, PMTK Supply voltage: 5V/3.3V Operating current:13mA Operating temperature:-40℃-85℃ Color:As Shown Material:plastic Package Contents: 1 * expansion boar
