Trimble SNM910 field cellular modem
Contact us about this product
The new IBSS provides GNSS correction information over the Internet using cellular services instead of relying solely on site radio communications, which can be subject to range limitations and black spots. IBSS is an add-on subscription to Trimble modular base stations and all rovers. To leverage the service, contractors simply connect their base stations to the IBSS using a wireless Local Area Network (LAN) or cellular modem technology to provide GNSS corrections over longer distances than normally possible with radio and repeater technology. The Trimble SNM910 cellular modem is designed specifically to connect a Trimble base station to the Internet and the IBSS server in situations where a wired LAN connection is not practical or desirable.
The new service extends precise GNSS coverage to remote or offsite project areas such as borrow pits, dump sites or other projects within a 30 kilometer (18 mile) range and provides more flexibility for the setup of GNSS infrastructure on large projects. This is especially useful for companies running multiple projects within a 30 kilometer (18 mile) radius to solve radio outage problems on large projects or in difficult terrain. Location RTK accuracies can be achieved using IBSS at greater distances. This is useful for new site reconnaissance or for initial site works such as setting site limits, clearance lines or silt fencing and topsoil stripping without the need to set up a local base station.
