{"title":"GPS-RTK Dead Reckoning Breakout - ZED-F9R (Qwiic)","handle":"sparkfun-gps-rtk-dead-reckoning-breakout-zed-f9r-qwiic-1","url":"/products/sparkfun-gps-rtk-dead-reckoning-breakout-zed-f9r-qwiic-1","description":"This high-precision GNSS breakout is built around the u-blox ZED-F9R, combining RTK positioning with Automotive Dead Reckoning (ADR) sensor fusion. It fuses a 3D IMU sensor, wheel ticks, a vehicle dynamics model, correction data and GNSS measurements to provide accurate and continuous positioning.The ZED-F9R is a 184-channel u-blox F9 engine receiver for GPS, GLONASS, Galileo and BeiDou. It operates as an RTK rover, so it needs a base station or correction source, and is well suited to autonomous robots and vehicles working in dense urban areas, covered spaces, short tunnels or parking garages.Two Qwiic connectors make I2C connection solder-free, while 0.1\"-spaced pins are broken out for breadboard use. The board also includes an integrated u.FL antenna connector, and it requires a suitable external antenna and cable for operation.Configuration can be handled through u-blox u-center or the SparkFun Arduino Library, including settings such as baud rates, update rates, geofencing, spoofing detection, external interrupts and SBAS/D-GPS. An on-board rechargeable battery powers the RTC to help reduce time-to-first-fix, and v1.2 updates the board silkscreen.Features:2x Qwiic ConnectorsIntegrated u.FL connector for use with antenna of your choiceConcurrent reception of GPS, GLONASS, Galileo and BeiDouReceives both L1C/A and L2C bandsBuilt-In Accelerometer and GyroscopeSoftware ConfigurableGeofencingOdometerSpoofing DetectionExternal InterruptPin ControlLow Power ModeMany others!Supports NMEA, UBX, and RTCM protocols over UART or I2C interfacesSpecifications:GNSS Receiver: 184-Channel GNSS ReceiverHorizontal Position Accuracy: 0.01m with RTKMax Navigation Rate: Up to 30HzTime to First Fix - Cold: 24sTime to First Fix - Hot: 2sMax G: ≤4GMax Altitude: 80km (49.7 miles)Max Velocity: 500m/s (1118mph)Velocity Accuracy: 0.05m/sHeading Accuracy: 0.2 degreesTime Pulse Accuracy: 30nsVoltage: 5V or 3.3V but all logic is 3.3VCurrent: ~85mA to ~130mA (varies with constellations and tracking state)Dimensions: 43.18mm x 50.8mm (1.7in x 2.0in)Weight: 11.05g","vendor":"SparkFun","product_type":"GNSS Breakout","in_stock":true,"options":[],"variants":[{"id":15858,"title":"Default Title","sku":"SF-GPS-22693","mpn":"GPS-22693","price":622.05,"on_sale":false,"in_stock":true,"available_quantity":3}]}
