{"product_id":"sparkfun-rtk-surveyor-7","title":"SparkFun RTK Surveyor","description":"\u003cp\u003eThe SparkFun RTK Surveyor is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying, this preprogrammed device can also be used for autonomous driving, navigation, asset tracking and any other application where there is a clear view of the sky.\u003c\/p\u003e\n\u003cp\u003eThe RTK Surveyor can also be used as a base station. With the flick of a switch, two RTK Surveyors can be used to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth connection via an ESP32 WROOM enables the user to use the RTK Surveyor with their choice of GIS application on a phone or tablet. The built in battery allows field use for up to four hours and is compatible with common USB battery banks.\u003c\/p\u003e\n\u003cp\u003eThis device can be used in four modes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGNSS Positioning (~30cm accuracy)\u003c\/li\u003e\n\u003cli\u003eGNSS Positioning with RTK (1.4cm accuracy)\u003c\/li\u003e\n\u003cli\u003eGNSS Base Station\u003c\/li\u003e\n\u003cli\u003eGNSS Base Station NTRIP Server\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn \u003cstrong\u003ePosition\u003c\/strong\u003e mode the device receives L1\/L2 signals from a user-provided antenna and the high-grade GNSS receiver provides lat\/long and altitude with accuracies around 300mm.\u003c\/p\u003e\n\u003cp\u003eIn \u003cstrong\u003ePositioning with RTK\u003c\/strong\u003e mode the device receives L1\/L2 signals from the antenna and correction data from a base station. The correction data can be obtained from a cellular link to online correction sources or over a radio link to a 2nd RTK Surveyor setup as a base station.\u003c\/p\u003e\n\u003cp\u003eIn \u003cstrong\u003eBase Station\u003c\/strong\u003e mode the device is mounted to a temporary position (like a tripod) and begins transmitting correction data over a radio or internet connection. A base is often used in conjunction with a second unit set to 'Positioning with RTK' to obtain the 14mm relative accuracy.\u003c\/p\u003e\n\u003cp\u003eIn \u003cstrong\u003eBase Station NTRIP Server\u003c\/strong\u003e mode the device is mounted to a semi or permanently fixed position (like a roof) and connects over WiFi to transmit the correction data to a NTRIP caster so that any rover can access the correction data over a cellular or internet connection. This type of base is a very easy way to setup a very precise absolute correction source.\u003c\/p\u003e\n\u003cp\u003eTwo cables are provided with the RTK Surveyor allowing a user to plug on our easy to use Serial Telemetry Radios or their own radio link. If a local correction source is within 10km, a user can also use their phone to provide correction data over the Bluetooth link (no external radio needed!).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChanges:\u003c\/strong\u003e This version uses a reinforced edge mount SMA connector for better resiliency when a fixed 'stub' antenna is used.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The SparkFun RTK Surveyor is just the enclosed device and does NOT include an antenna, serial telemetry radio, or associated mounting pieces.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/sparkfun-rtk-surveyor-hookup-guide\/all?_ga=2.124928396.706307820.1631195057-1145740810.1627900761\" target=\"_blank\"\u003eGet started with the SparkFun RTK Surveyor Hookup Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eGNSS Receiver: ZED-F9P\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConcurrent reception of GPS, GLONASS, Galileo and BeiDou\u003c\/li\u003e\n\u003cli\u003eReceives both L1C\/A and L2C bands\u003c\/li\u003e\n\u003cli\u003eCurrent: 68mA - 130mA (varies with constellations and tracking state)\u003c\/li\u003e\n\u003cli\u003eTime to First Fix: 25s (cold), 2s (hot)\u003c\/li\u003e\n\u003cli\u003eMax Navigation Rate:\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003ePVT (basic location over UBX binary protocol) - 25Hz\u003c\/li\u003e\n\u003cli\u003eRTK - 20Hz\u003c\/li\u003e\n\u003cli\u003eRaw - 25Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eHorizontal Position Accuracy:\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003e2.5m without RTK\u003c\/li\u003e\n\u003cli\u003e0.010m with RTK\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eMax Altitude: 50km (31 miles)\u003c\/li\u003e\n\u003cli\u003eMax Velocity: 500m\/s (1118mph)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBluetooth Transceiver: ESP32 WROOM\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eXtensa® dual-core 32-bit LX6 microprocessor\u003c\/li\u003e\n\u003cli\u003eUp to 240MHz clock frequency\u003c\/li\u003e\n\u003cli\u003e4MB of flash storage\u003c\/li\u003e\n\u003cli\u003e520kB internal SRAM\u003c\/li\u003e\n\u003cli\u003eIntegrated 802.11 BGN WiFi transceiver\u003c\/li\u003e\n\u003cli\u003eIntegrated dual-mode Bluetooth (classic and BLE)\u003c\/li\u003e\n\u003cli\u003eHardware accelerated encryption (AES, SHA2, ECC, RSA-4096)\u003c\/li\u003e\n\u003cli\u003e2.5 µA deep sleep current\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eOverall Device\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInternal Battery: LiPo 1000mAh with 500mA charging\u003c\/li\u003e\n\u003cli\u003eRadio Port: 3.3V TTL Serial (57600bps RTCM TX\/RX)\u003c\/li\u003e\n\u003cli\u003eData Port: 3.3V TTL Serial (115200bps NMEA)\u003c\/li\u003e\n\u003cli\u003eWeight: 132g (entire device including battery)\u003c\/li\u003e\n\u003cli\u003eDimensions: 118mm x 79mm x 30mm (4.7in x 3.1in x 1.2in)\u003c\/li\u003e\n\u003cli\u003e1x \u003ca href=\"\/en-eu\/collections\/qwiic\" target=\"_blank\"\u003eQwiic\u003c\/a\u003e Connector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/c\/1\/b\/d\/8\/SparkFun_RTK_Surveyor-v13.pdf\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/e\/9\/1\/7\/f\/SparkFun_GPS_RTK_Surveyor-Eagle_Files.zip\" target=\"_blank\"\u003eEagle files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/sparkfun-rtk-surveyor-hookup-guide\/all?_ga=2.164384441.706307820.1631195057-1145740810.1627900761\" target=\"_blank\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_RTK_Firmware\" target=\"_blank\"\u003eFirmware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_RTK_Surveyor\" target=\"_blank\"\u003eHardware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":39450078609491,"sku":"GPS-18443","price":463.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/17369-GPS_RTK_Surveyor_-_Enclosed-01.jpg?v=1631278707","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/sparkfun-rtk-surveyor-7","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
