SparkFun RTK Express Kit
Description SparkFun RTK Express Kit Offers a Bluetooth enabled multi-band GNSS receiver Comes with USB A to C cable Receives both L1C/A and L2C bands Embedded OLED display USB wall charger: 5 V The SparkFun RTK Express Kit is a Bluetooth-enabled multi-band GNSS receiver based on the ESP32 from Espressif and the ZED-F9P from u-blox. Power it up and you'll have 300 mm approximate accuracy out of the box and 14 mm accuracy with RTCM corrections. This kit provides the L1/L2 antenna, adapters, interface cables, and chargers needed for general GNSS use. The RTK Express Kit has everything you need to get centimeter-level global positioning measurements using GNSS RTK. This is a handy carrying case to protect the most expensive bits, allowing you to quickly attach the L1/L2 antenna and RTK Express 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. 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 32 GB). Note: The L1/L2 antenna has a 5/8 inch thread which will fit most surveying platforms. The kit includes a 5/8 to 1/4 inch adapter as well which will fit most camera monopods and tripods. You may need additional adapters for your specific equipment.
