SparkFun RTK Surveying Kit

SparkFun RTK Surveying Kit features everything that users need to get cm-level global positioning measurements using GNSS RTK. The surveying kit comes in a handy carrying case to protect the most expensive bits. This allows users to quickly attach the L1/L2 antenna and RTK Surveyor housing to the pole or tripod of their choice. The kit includes all the antenna bits, cables, and chargers that users 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. The users can flip the switch to 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.
