{"title":"4G GNSS-RTK Positioning Kit (EMEA & Thailand)","handle":"4g-gnss-rtk-high-precision-positioning-kit-emea-thailand-gps-glonass-galileo-bds-qzss","url":"/products/4g-gnss-rtk-high-precision-positioning-kit-emea-thailand-gps-glonass-galileo-bds-qzss","description":"Designed for high-accuracy navigation projects, this kit uses Network RTK to deliver 5 cm + 1 ppm centimetre-level positioning across a typical 15-20km operational range. Its onboard 4G module receives RTCM correction data from a CORS network via the Ntrip protocol, removing the need for a local base station when CORS coverage and 4G signal are available.The receiver tracks GPS, GLONASS, Galileo, BDS and QZSS, with multi-band support to help reduce ionospheric interference and multipath effects. It can converge in under 10 seconds and outputs positioning data through a flexible Gravity interface with selectable I2C or UART for microcontrollers and single-board computers.Deployment is centred around inserting a 4G SIM card and configuring the unit with CORS account credentials. The kit includes the RTK Mobile unit, GNSS antenna, 4G/LTE right-angle rubber duck antenna, flathead screwdriver, plug-in terminal block and a 30cm PH2.0-4P connection cable. DFRobot also provides a product wiki for setup information.Features:Network RTK over 4G: Receives RTCM correction data from a CORS network via Ntrip.Centimetre-level positioning: Delivers 5 cm + 1 ppm accuracy over a typical 15-20km operational range.No local base station required: Uses an established CORS network instead of a 3-5km local radio link.Multi-constellation GNSS: Supports GPS, GLONASS, Galileo, BDS and QZSS.Multi-band reception: Supports bands including GPS L1/L5, Galileo E1/E5a and BDS B1l/B2a.Fast convergence: Achieves convergence in under 10 seconds.Gravity interface: Selectable I2C and UART signal outputs for project integration.Autonomous Rover: Build a rover, autonomous lawnmower, or delivery bot that navigates with pinpoint precision.Asset Tracking: Create a high-precision tracker for fleet vehicles, expensive equipment, or even a lost drone.Data Logging: Map a precise trajectory, conduct simple land surveys, or create a set of fixed monitoring points for science projects.Outdoor Robotics: Give any outdoor robot a reliable, centimeter-level understanding of its position in the world.Specifications:Power Interface: Gravity interface, 3.3~5VType-C: For 4G module power (requires separate power supply)Output Signal: I2C / UARTAntenna Interface: SMAReception Bands:GPS/QZSS: L1 C/A, L5GLONASS: L1Galileo: E1, E5aBDS (BeiDou): B1l, B2aDefault Constellations: GPS + GLONASS + Galileo + BDS + QZSSConcurrent Tracking Constellations: 4+ QGNSSSBAS: WAAS, EGNOS, MSAS, GAGANFunction: RTKHorizontal Positioning Accuracy:Autonomous: 1 mRTK: 5 cm + 1 ppmVelocity Accuracy: 0.03 m/s1PPS Accuracy: 20 nsRTK Convergence Time: < 10 sSensitivity:Acquisition: -145 dBmTracking: -165 dBmReacquisition: -157 dBmDynamic Performance:Max Altitude: 10000 mMax Velocity: 500 m/sMax Acceleration: 4 gNavigation Update Rate (RTK): 1 HzRaw Data Output Rate (GNSS): 1 HzProtocol: NMEA 0183 / RTCM 3.xWeight: about 380gSupported Countries/Regions: EMEA & ThailandFor best results, use it outdoors away from tree shade, bridges and strong electromagnetic interference. The 4G module requires separate Type-C power and should be powered first; check CORS account coverage before setup.","vendor":"DFRobot","product_type":"GNSS RTK Kit","in_stock":true,"options":[],"variants":[{"id":15613,"title":"Default Title","sku":"DF-KIT0212","mpn":"KIT0212","price":284.05,"on_sale":false,"in_stock":true,"available_quantity":86}]}
