Transforming the way the world works



The Trimble BD920-W3G module has been designed for applications requiring centimeter accuracy in a compact package. By integrating wireless communications on the same module the task of receiving and transmitting data such as RTK corrections is greatly simplified. A single intuitive web interface allows a variety of use cases to be supported. In addition to GNSS base and rover setups with Wi-Fi or UMTS modem the module also allows simultaneous customer access to the internet.

Both GNSS and communication components are fully shielded. This design ensures the high quality signals are protected from the sources of EMI on the host platform. It also significantly reduces radiated emissions which speeds compliance certification and time to market.
