{"title":"SparkFun Triband GNSS RTK Breakout - UM980","handle":"sparkfun-triband-gnss-rtk-breakout-um980","url":"/products/sparkfun-triband-gnss-rtk-breakout-um980","description":"The SparkFun Triband GNSS RTK Breakout features the UM980 GNSS high precision RTK position module from Unicore Communications. The UM980 is a 1408-Channel GNSS Receiver based on the Nebulas IV™ that is able to simultaneously track GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b/E6, Beidou B1I/B2I/B3I/B1C/B2a/B2b, QZSS L1/L2/L5, and SBAS. With this board, you will be able to know where your (or any object's) X, Y, and Z location is within roughly the width of your fingernail. When an RTK solution is reached, the module can achieve a horizontal accuracy of about 8mm (~0.3 inches) and vertical accuracy of 15mm (~0.59 inches). The UM980 is capable of both rover and base station operations.\nWe've included a rechargeable backup battery to keep the latest module configuration and satellite data available. This battery helps 'warm-start' the module, decreasing the time-to-first-fix dramatically. This module features a survey-in mode, allowing the module to become a base station and produce RTCM 3.x correction data. A SMA connector is included for a secure connection to a Triband GNSS antenna.\nCurrently, serial UART is only supported on the UM980 module. All three serial UART ports have been broken out to the USB-C connector via CH340, 4-pin locking JST connector, and BlueSMiRF header. Unique pins have also been broken out to the edge of the board. Various jumpers are also included to configure power and LEDs.\n\n\nGet Started with the SparkFun UM980 Triband GNSS RTK Breakout Guide\nFeatures:\n\nModule has a typical low power-consumption of ~480mW\n1408-Channel GNSS Receiver based on the Nebulas IV™\nConcurrent reception of GPS, GLONASS, Galileo, BeiDou, QZSS\n\nGPS: L1C/A, L1C*, L2P(Y), L2C, L5\nGLONASS: L1, L2\nGalileo: E1, E5a, E5b, E6*\n\nBeidou: B1I, B2I, B3I, B1C, B2a, B2b*\n\nQZSS: L1, L2, L5\nSBAS\n\n\nHorizontal Accuracy\n\nAutonomous: 1.5m\nDGPS: 0.4m\nRTK: 0.8cm + 1ppm\n\n\nVertical Accuracy\n\nAutonomous: 2.5m\nDGPS: 0.8m\nRTK: 1.5cm + 1ppm\n\n\n50Hz Data Update Rate*\n\nTime-To-First-Fix:\n\nCold: 30s\nWarm: 20s\nHot: 5s\n\n\nCoCom Limits\n\nMax Altitude: 18000m\nMax G: <5G\nMax Velocity: 515m/s\n\n\nVelocity Accuracy (RMS): 0.03m/s\nTime Accuracy (RMS): 20ns\nSupports NMEA, RTCM, and Unicore (w/ specific firmware) protocols over UART\nIntegrated SMA connector for use with multiband GNSS antenna of your choice\nVoltage: 5V or 3.3V but all logic is 3.3V\nUSB Type C Connector\nESD Protection Diodes for USB Data Lines\nBuilt-in Resettable PTC Fuse 6V/1.5A\nCH340 USB-to-serial converter on UART1 Port\nLocking JST Connector for UART2 Port\nBlueSMiRF Footprint for UART3 Port\nBackup Battery for Hot Start\nLEDs\n\nPWR: Power Indicator\nPVT: Position, Voltage, Time\nPPS: Pulse-Per-Second Indicator\nRTK: Reak-Time-Kinematic Fixed Solution Indicator\n\n\nJumpers\n\nSHLD: USB Shield\nVSEL: Voltage Select for Locking JST Connector Port\nPWR: Power LED\nPVT: Position, Voltage, Time LED\nPPS: Pulse-Per-Second LED\nRTK: Real-Time Kinematic LED\nBT-VCC: Voltage Select for Bluetooth Port\nVANT: Voltage Antenna Select\n\n\nDimensions: 2.0in. x 2.0in.
