{"title":"Quadband GNSS RTK Heading Breakout - LG580P (Qwiic)","handle":"sparkfun-quadband-gnss-rtk-with-heading-breakout-lg580p-qwiic","url":"/products/sparkfun-quadband-gnss-rtk-with-heading-breakout-lg580p-qwiic","description":"This high-precision positioning breakout is built around the Quectel LG580P GNSS module, giving projects centimetre-level RTK positioning plus instantaneous heading when used with two GNSS antennas. Unlike systems that need to move before they can infer direction, the dual-antenna setup can determine heading from a standstill.The receiver supports quad-band, multi-constellation GNSS across GPS, GLONASS, Galileo, BDS, QZSS and NavIC, with correction support for RTK/RTCM, SBAS and selected PPP services. It is suited to demanding navigation work such as robotics, autonomous vehicles, precision agriculture and mapping systems.Connectivity is designed for both quick prototyping and embedded builds. The board includes solder-free Qwiic connectors for I²C communication, plus broken-out UART, SPI and CAN interfaces, USB-C, status LEDs, mounting holes and antenna connections. Documentation includes design files, board dimensions, a hookup guide, QGNSS software and LG580P application notes.Note: According to Quectel, I²C support is still under development and is expected via a future firmware update. Corrections for some PPP services, such as HAS E6, have not yet been implemented.Features:GNSS module: Quectel LG580P quad-band, GNSS moduleConcurrent signal reception: 5 + QZSSFrequency bands: L1, L2, L5, E6 frequency bandsCorrections: RTK and RTCM correctionsSBAS augmentation: WAAS, EGNOS, BDSBAS, MSAS, GAGAN, KASS, ASECNA, SouthPAN, and SDCMPPP services*: BDS PPP-B2b, QZSS CLAS, MADOCA-PPP, and Galileo HAS*Heading: Instantaneous heading using two GNSS antennasSignal performance: Professional-grade interference detection and elimination algorithmsAlgorithms: Advanced RTK and heading algorithmsGNSS constellation: GPS (USA)GNSS constellation: GLONASS (Russia)GNSS constellation: Galileo (EU)GNSS constellation: BDS (China)GNSS constellation: QZSS (Japan)GNSS constellation: NavIC (India)SBAS system: WAAS (USA)SBAS system: SDCM (Russia)SBAS system: EGNOS (EU)SBAS system: BDSBAS (China)SBAS system: MSAS (Japan)SBAS system: GAGAN (India)SBAS system: KASS (Korea)SBAS system: ASECNA (Africa)SBAS system: SouthPAN (Aus/NZ)Mounting: Four mounting holesQwiic: 4-pin JST Qwiic connector* (x2)USB: USB-C connectorBackup: Backup batteryLG580P: High-precision RTK, and Heading GNSS moduleInterface: UART (x3)Interface: SPI* (x1)Interface: I2C* (x1)Interface: CAN* (x1)Specifications:Breakout board dimensions: 1.70\" x 1.80\" (43.2mm x 45.7mm)Mounting holes: Four mounting holesMounting hole compatibility: 4-40 screw compatiblePTH pins: 25 PTH PinsQwiic connectors: 4-pin JST Qwiic connector* (x2)UART interfaces: UART interfaces (x3)USB connector: USB-C connectorBlueSMiRF/Serial-to-UART header: 6 PTH pins (BlueSMiRF/Serial-to-UART)Locking JST connector: 4-pin locking JST connectorPWR LED: Red 3.3V power indicatorPPS LED: Yellow Pulse-Per-Second indicatorRTK LED: White RTK correction indicatorHEAD LED: Green heading status indicatorPVT LED: Blue PVT status indicatorSupply Voltage: 3.0–3.6VCurrent Consumption - Normal Operation Acquisition: 98mA (323.4mW) (Acquisition)Current Consumption - Normal Operation Tracking: 116mA (382.8mW) (Tracking)Current Consumption - Power Saving Mode Backup Mode: 18μA (59.4μmW) (Backup Mode)GPS frequency bands: L1 C/A, L5, L2CGLONASS frequency bands: L1, L2Galileo frequency bands: E1, E5a, E5b, E6BDS frequency bands: B1I, B1C, B2a, B2b, B2I, B3IQZSS frequency bands: L1 C/A, L5, L2C, L6NavIC frequency bands: L5SBAS frequency bands: L1L-band PPP - PPP: B2bL-band PPP - QZSS: L6L-band PPP - Galileo HAS: E6*Tracking Channels: 1040Horizontal Position Accuracy - Autonomous: 1mHorizontal Position Accuracy - RTK: 0.8cm + 1ppmVertical Accuracy - Autonomous: 1.5mVertical Accuracy - RTK: 1.5cm + 1ppmHeading Accuracy: 0.1°Velocity Accuracy Without Aid: 0.03m/sAccuracy of 1PPS Signal: 5nsRTK Convergence Time: 5sTime to First Fix - Cold Start: 28sTime to First Fix - Warm Start: 28sTime to First Fix - Hot Start: 1.8sSensitivity - Acquisition: -145dBmSensitivity - Tracking: -160dBmSensitivity - Reacquisition: -155dBmDynamic Performance - Maximum Altitude: 10000mDynamic Performance - Maximum Velocity: 490m/sDynamic Performance - Maximum Acceleration: 4gUpdate Rate - Default: 10HzUpdate Rate - Max: 20HzAntenna Interface: External active antennaAntenna Interface - Power Supply: ExternalUART: UART (x3)Baud Rate: 9600–3000000bpsDefault baud rate: 460800bpsProtocol: NMEA 0183/RTCM 3.x/QGCSPI: SPI* (x1)I2C: I2C* (x1)CAN: CAN* (x1)Operating temperature: -40°C to +85°CFootprint: 21mm × 16mm × 2.7mmWeight: 1.4gFeature status: *: Feature is still under developmentA strong fit for advanced GNSS rover, base station, heading and navigation builds where high update rates, multi-band reception and multiple host interfaces are needed.","vendor":"SparkFun","product_type":"GNSS RTK Breakout","in_stock":true,"options":[],"variants":[{"id":15864,"title":"Default Title","sku":"SF-GPS-28019","mpn":"GPS-28019","price":462.1,"on_sale":false,"in_stock":true,"available_quantity":22}]}
