The controller is equipped with a remarkable 5.5" TFT display that boasts a resolution of 1920 x 1080 pixels and a brightness of 500 nits, along with a compact QWERTY keyboard. The S55G enables users to work in real-time with RTK corrections while simultaneously recording raw data for post-processing. It also supports the use of an external antenna SA85, which can further enhance the precision of the collected data, allowing users to achieve high accuracy in their field work, approximately < 1 cm.
