The RTK Surveyor Kit has everything you need to get centimeter level global positioning measurements using GNSS RTK. We've created a handy carrying case to protect the most expensive bits, allowing you to quickly attach the L1/L2 antenna and RTK Surveyor housing to the pole or tripod of your choice. The kit includes all the antenna bits, cables and chargers you need to jump right into the field.

The RTK Surveyor is a Bluetooth enabled multi-band GNSS receiver based on the ESP32 from Espressif and the ZED-F9P from u-blox. Flip the switch and you'll have 300mm approximate accuracy out of the box and 18mm accuracy with RTCM corrections. This kit provides the L1/L2 antenna, adapters, interface cables, and chargers needed for general GNSS use.

We generally recommend using your cellular phone as the radio backhaul for RTCM but you can also use your own, higher power radios as long as they support 57600bps. Sparkfun also recommend logging all data to your phone over Bluetooth. This is as simple as checking a box within SW Maps. But if you prefer to do long surveys, or need to deal with RAWX measurements where a phone will not be present, a microSD card should be purchased (any size up to 32GB).

Please keep in mind that you will need to provide your own mono-pod or tripod as well as a cell-phone type holder for securing the RTK Express Plus to your mono-pod or tripod. We've found this style clamp and this style clamp work well. Your mileage may vary.

Note: The L1/L2 antenna has a 5/8" thread which will fit most surveying platforms. The kit includes a 5/8" to 1/4" adapter as well which will fit most camera mono-pods and tripods. You may need additional adapters for your specific equipment.
