SparkFun RTK Express Kit

SparkFun RTK Express Kit includes everything needed to get centimeter-level global positioning measurements using GNSS RTK. A handy carrying case is included for protection and allows quick attachment of the L1/L2 antenna and RTK Express housing to a pole or tripod. The kit includes all the antenna bits, cables, and chargers needed to jump right into the field.
