SKU: GPS-18443 Category: Tag: Brand:

The SparkFun RTK Surveyor is an easy to use GNSS receiver for centimetre-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.   This unit requires an external antenna along with a TNC to SMA cable.

SKU: GPS-18443 Category: Tag: Brand:

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.

This device can be used in four modes:

  • GNSS Positioning (~30cm accuracy)
  • GNSS Positioning with RTK (1.4cm accuracy)
  • GNSS Base Station
  • GNSS Base Station NTRIP Server

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.

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 setup as a 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.

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 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.

Two 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!).

Note: The SparkFun RTK Surveyor is just the enclosed device and does NOT include an antenna, serial telemetry radio, or associated mounting pieces. These items will need to be purchased separately from the Hookup Accessories below.
