The SparkFun RTK Express Kit is a comprehensive solution for achieving centimeter-level global positioning measurements using GNSS RTK. This kit is designed with convenience in mind, featuring a carrying case to protect the valuable components and allowing for quick attachment of the L1/L2 antenna and RTK Express housing to your chosen pole or tripod. The kit is complete with all the necessary antenna components, cables, and chargers, making it ready for immediate field use.
The RTK Express is a multi-band GNSS receiver that comes with Bluetooth® functionality. It is based on the ESP32 from Espressif and the ZED-F9P from u-blox. Once powered up, it offers an approximate accuracy of 300mm right out of the box, which can be refined to 14mm with RTCM corrections. The kit provides all the necessary L1/L2 antenna, adapters, interface cables, and chargers for general GNSS use.
The RTK Express Kit is compatible with common GIS software for Android and iOS, including SW Maps, Field Genius, SurvPC, Survey Master, Vespucci, QGIS, QField, and any GIS software that supports NMEA over Bluetooth. For RTCM radio backhaul, it is recommended to use your cellular phone, but you can also use your own higher power radios as long as they support 57600bps. All data can be logged to your phone over Bluetooth®, or if you prefer long surveys or need to deal with RAWX measurements where a phone will not be present, a microSD card should be purchased separately (any size up to 32GB).
For securing the RTK Express to your mono-pod or tripod, you will need to provide your own cell-phone type holder. Please note that the L1/L2 antenna has a 15.875mm thread which will fit most surveying platforms. The kit includes a 15.875mm to 6.35mm adapter which will fit most camera mono-pods and tripods. You may need additional adapters for your specific equipment.
It's important to note that the SparkFun RTK Express is not designed for permanent outdoor mounting. The L1/L2 antenna should be mounted outside with an SMA cable running to the RTK Express that is located inside or protected from the elements.
