{"title":"RTK Express GNSS Surveying Kit","handle":"sparkfun-rtk-express-kit","url":"/products/sparkfun-rtk-express-kit","description":"This field-ready kit is made for centimetre-level global positioning measurements using GNSS RTK. It centres on the RTK Express, a Bluetooth® enabled multi-band GNSS receiver based on the Espressif ESP32 and u-blox ZED-F9P.The kit is supplied in a carrying case and includes the RTK Express GNSS Receiver, RTK Kit Carrying Case, GNSS L1/L2 Multi-Band Antenna - TOP106, Antenna Interface Cable - SMA to TNC (300mm), 1/4\" to 5/8\" Antenna Thread Adapter, USB Wall Charger - 5V, 2A, USB A to C Cable - 0.8m, Data Cable and Radio Cable.It works with common GIS software on Android and iOS, and can send NMEA data over Bluetooth or TCP. For RTCM corrections, SparkFun generally recommends using a mobile phone as the radio backhaul, though external higher-power radios can be used if they support 57600bps.You will need to provide your own mono-pod or tripod and a phone/enclosure holder. The RTK Express is not designed for permanent outdoor mounting; for fixed installations, keep the receiver indoors or protected from the elements and run an SMA cable to the outdoor antenna.Features:SWMaps (Android and iOS)ArcGIS Survey123Field GeniusSurvPCSurvey MasterVespucciQGISQField (Android and iOS)Any GIS software that uses Bluetooth SPP or BLEAny GIS software that supports NMEA over Bluetooth or TCPSpecifications:GNSS Receiver: ZED-F9PConcurrent reception: GPS, GLONASS, Galileo and BeiDouBands received: L1C/A and L2CCurrent: 68mA - 130mA (varies with constellations and tracking state)Time to First Fix: 25s (cold), 2s (hot)PVT (basic location over UBX binary protocol): 25HzRTK: 20HzRaw: 25HzHorizontal Position Accuracy without RTK: 2.5mHorizontal Position Accuracy with RTK: 0.010mMax Altitude: 50km (31 miles)Max Velocity: 500m/s (1118mph)Approximate accuracy out of the box: 300mmAccuracy with RTCM corrections: 14mmBluetooth® Transceiver: ESP32 WROOMMicroprocessor: Xtensa® dual-core 32-bit LX6 microprocessorClock frequency: Up to 240MHzFlash storage: 16MBInternal SRAM: 520kBWiFi transceiver: Integrated 802.11 BGN WiFi transceiverBluetooth®: Integrated dual-mode Bluetooth® (classic and BLE)Encryption: Hardware accelerated encryption (AES, SHA2, ECC, RSA-4096)Deep sleep current: 2.5 µAInternal Battery: LiPo 1300mAh with 500mA chargingRadio Port: 3.3V TTL Serial (57600bps RTCM TX/RX)Data Port: 3.3V TTL Serial (115200bps NMEA)Display: Embedded OLED Display for available satellites, data logging, and more.Controls: Push button controlsWeight: 162g (entire device including battery)Dimensions: 132mm x 101mm x 32mm (5.2in x 3.9in x 1.2in)Qwiic Connector: 1x Qwiic ConnectorGIS software compatibility: Works with common GIS software including: SW Maps, SurvPC, Field Genius, et al.Antenna: GNSS Multi-Band L1/L2 Surveying AntennaGain: ≥5dBiLNA Gain: 40dBL1: 1555 to 1615MHzL2: 1198 to 1278MHzAntenna Impedance: 50 OhmOverall antenna weight: 335gBare antenna element weight: 160gBare antenna element weight details: including MMCX connector, with RF shieldAntenna dimensions: 148 x 55mmWaterproof rating: IP67Antenna connector: Female TNCAntenna thread: 5/8\"Included antenna thread adapter: 5/8\" to 1/4\"External radio support: 57600bpsmicroSD card support: any size up to 32GBCertified OSHW: US002050Optional items not included are a camera mono-pole or tri-pod, phone/enclosure holder, Telemetry Radios - 500mW and microSD Card - 16GB.","vendor":"SparkFun","product_type":"GNSS RTK Kit","in_stock":false,"options":[],"variants":[{"id":15789,"title":"Default Title","sku":"SF-GPS-18380","mpn":"GPS-18380","price":1401.3,"on_sale":false,"in_stock":false,"available_quantity":0}]}
