Reach is a compact and affordable multi-GNSS RTK receiver with built-in IMU. It can provide coordinates down to centimeters in RTK mode. RTK mode requires a pair of receivers: one is stationary which provides corrections, another one moving which applies corrections and provides its precise coordinates. Reach runs open-source RTK engine “RTKLIB” written by Tomoji Takasu.
PLEASE NOTE THAT TWO RECEIVERS ARE REQUIRED FOR RTK MODE.
