Designed and manufactured in Boulder, Colorado, USA, the SparkFun RTK Facet is your one-stop shop for high precision geolocation and surveying needs. For basic users, its incredibly easy to get up and running; for advanced users, the RTK Facet is a flexible and powerful tool. With just a few minutes of setup, the RTK Facet is one of the fastest ways to take centimeter-grade measurements. By connecting your phone to the RTK Facet Wirelessly, your phone can act as the radio link to provide correction data as well as receive the NMEA output from the device. This is exactly how $10,000 surveying devices have been operating for the past decade - we just made it easier, smaller, and a lot more economical.
Under the hood of the SparkFun RTK Facet is an ESP32 WROOM connected to a ZED-F9P as well as some peripheral hardware (LiPo fuel gauge, microSD, etc). Additionally, housed under the dome of the RTK Facet is a surveyor grade L1/L2 antenna. It is the same element found within our GNSS Multi-Band L1/L2 Surveying Antenna. The built-in antenna has an ARP of 61.4mm from the base to the measuring point of the L1 antenna and an ARP of 57.4mm to the measuring point of the L2 antenna.
This device can be used in four modes:
GNSS Positioning (~30cm accuracy) - also known as 'Rover'
GNSS Positioning with RTK (1.4cm accuracy) - also known as 'Rover with RTK Fix'
GNSS Base Station
GNSS Base Station NTRIP Server
At Power On the device will enter Rover or Base mode; whichever state the device was in at the last power down. When the POWER/SETUP button is pressed momentarily, a menu is presented to change the RTK Facet to Rover or Base mode. The display will indicate the change with a small car or flag icon.
