South NaviStation_ is an integrated high-performance system based on Android, consisting of a total station and a GNSS RTK receiver, which is designed to perform combined surveying. Using NaviStation there is no need to lay down the points of plan-altitude justification, calculate and equalize moves, carry out additional processing of total station and GNSS receiver measurements. NaviStation will take care of these time-consuming and costly operations. All you need is to install the device and perform a tacheometric survey, while the coordinates of all standing points will be determined by the GNSS RTK receiver. Full synchronization of the total station and the GNSS receiver will provide a joint coordinate solution not only of course points, but also of all survey points.
