[November 19, 2019: postscript] If you are considering installing as an RTK reference station, the new model AgriBus-GMiniR designed for RTK is the best choice.

Procedures for RTK-positioning using AgriBus-GMini (hereinafter referred to as GMini)First, we will explain how to set the station as a reference station (Base). In order to distribute Base data to the Internet,The PC must always be connected to the Internet.

Preliminary steps – (A)

Change the settings of the u-blox’s GNSS modules on the GMini to those for the base station.

(Install the u-center on Windows PCs and write the configuration files for the base station to the GMini.)
