The SparkFun RTK Surveyor GPS-18443 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.

GNSS Positioning (~30cm accuracy): In Position 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.

GNSS Positioning with RTK (1.4cm accuracy): In Positioning with RTK 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 set up as a base station.

GNSS Base Station: In Base Station 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.

GNSS Base Station NTRIP Server: In Base Station NTRIP Server 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 an 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 set up a very precise absolute correction source.

Note: The SparkFun RTK Surveyor is just the enclosed device and does NOT include an antenna, serial telemetry radio, or associated mounting pieces.
