High-Precision Multi-Frequency GNSS Receiver 4GNSS Start for Accurate Positioning

4GNSS Start is a multi-frequency GNSS receiver of geodetic class with an external antenna. It is intended for high-precision determination of object location. It was created to be used as a base station for generation and transmission of RTK-requests, as well as for their reception and operation in the classic RTK mode, as well as in PPP and PPP-RTK modes. Receives signals of GLONASS, GPS, BeiDou, Galileo satellite systems. Control, configuration and work with the receiver is carried out using its own software Web Survey
