The SparkFun RTK Surveying 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. We 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). The RTK Surveying Kit works with common GIS software including SW Maps, SurvPC, Field Genius, and any GIS software that supports NMEA over Bluetooth.
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 Surveyor 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.

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Rookie - Basic hand tools are required and instructions will allow more freedom. You may need to make your own decisions on design. If sewing is required, it will be free-form.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

came for the documentation, stayed for the ease of use and accuracy.. in a world where there really aren't super cheap options for this kind of thing, i've found that this is one of very few "affordable" options (other than the unbundled board versions from sparkfun, emlid m2, etc..).. really like the switches, leds and overall ease - using a cellphone and new york state's ntrip (many states apparently will give you ntrip correction data for the cost of signing up..) we were able to get to cm accuracy with a cellphone and no sweat.. followed mounting product suggestions and got a jaunty surveying rover pole out of them..
Product is providing the expected features and specs Easy implementation in few minutes Very satisfied of this purchase
RTK Surveying is a cheap and ideal GNSS RTK device to test the MyCumulus Android app. Switching on, Bluetooth pairing, selecting the SparkFun RTK Surveying device in MyCumulus... and within a minute we got centimeter precision thanks to the NTRIP client in MyCumulus, streaming the RTCM correction data over Bluetooth. Especially as software developers, we don't need an expensive device that basically does the same as the SparkFun RTK Surveying.

I've been messing around with GPS surveying since the early 1990s, when Selective Availability was still a thing. Getting highly accurate absolute positional data has always been a challenge, one that is generally only solved by the application of large amounts of money. This kit removes that barrier! I use it in conjunction with SW Maps, a great free app (Android only, but no one who's serious about technology uses an iPhone anyway), and the NTRIP Client from Lance Lefebure (also free). I use it for RTK via an NTRIP server to give me corrections, but I'm considering getting a second unit to act as a base station for independence from corrections that are potentially over long baselines.
Very easy to set up, especially if you follow the Sparkfun guides. I added two phone clamps, and survey pole, and a survey level bubble. All up I probably have about $800 invested, which is amazing for the degree of absolute accuracy provided by the system. I pull the exported data into either QGIS or Autocad, depending on project needs. The workflow is simple.
Anyone who is interested in surveying accurately can bring this into their lives and perform great surveys with a minimal (equipment) learning curve - learning about surveying is another topic, but you can get some pretty good tuition online from any number of sources.
