{"product_id":"sparkfun-rtk-surveyor","title":"SparkFun RTK Surveyor","description":"\u003cp data-mce-fragment=\"1\"\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. The 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 data-mce-fragment=\"1\"\u003eThe RTK Surveyor works with common GIS software for Android and iOS including SW Maps\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/sparkfun.github.io\/SparkFun_RTK_Firmware\/gis_software\/#sw-maps\" data-mce-fragment=\"1\" data-mce-href=\"https:\/\/sparkfun.github.io\/SparkFun_RTK_Firmware\/gis_software\/#sw-maps\"\u003eAndroid\u003c\/a\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\/\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/apps.apple.com\/us\/app\/sw-maps\/id6444248083\" data-mce-fragment=\"1\" data-mce-href=\"https:\/\/apps.apple.com\/us\/app\/sw-maps\/id6444248083\"\u003eiOS\u003c\/a\u003e,\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.microsurvey.com\/products\/fieldgenius-for-android\/\" data-mce-fragment=\"1\" data-mce-href=\"https:\/\/www.microsurvey.com\/products\/fieldgenius-for-android\/\"\u003eField Genius\u003c\/a\u003e,\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.carlsonsw.com\/product\/carlson-survce\" data-mce-fragment=\"1\" data-mce-href=\"https:\/\/www.carlsonsw.com\/product\/carlson-survce\"\u003eSurvPC\u003c\/a\u003e,\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/docs.sparkfun.com\/SparkFun_RTK_Firmware\/gis_software\/#survey-master\" data-mce-fragment=\"1\" data-mce-href=\"https:\/\/docs.sparkfun.com\/SparkFun_RTK_Firmware\/gis_software\/#survey-master\"\u003eSurvey Master\u003c\/a\u003e,\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/play.google.com\/store\/apps\/details?id=de.blau.android\u0026amp;hl=en_US\u0026amp;gl=US\" data-mce-fragment=\"1\" data-mce-href=\"https:\/\/play.google.com\/store\/apps\/details?id=de.blau.android\u0026amp;hl=en_US\u0026amp;gl=US\"\u003eVespucci\u003c\/a\u003e,\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/qgis.org\/\" data-mce-fragment=\"1\" data-mce-href=\"https:\/\/qgis.org\/\"\u003eQGIS\u003c\/a\u003e,\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/docs.qfield.org\/get-started\/\" data-mce-fragment=\"1\" data-mce-href=\"https:\/\/docs.qfield.org\/get-started\/\"\u003eQField\u003c\/a\u003e, and any GIS software that supports NMEA over Bluetooth.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThis device can be used in four modes:\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eGNSS Positioning (~30cm accuracy)\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eGNSS Positioning with RTK (1.4cm accuracy)\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eGNSS Base Station\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eGNSS Base Station NTRIP Server\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-mce-fragment=\"1\"\u003eIn\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003cstrong data-mce-fragment=\"1\"\u003ePosition\u003c\/strong\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003emode 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 data-mce-fragment=\"1\"\u003eIn\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003cstrong data-mce-fragment=\"1\"\u003ePositioning with RTK\u003c\/strong\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003emode the device receives L1\/L2 signals from the antenna and correction data from a base station.
