Connected Base Station for Construction, Ag and Geospatial

Trimble has introduced the R750 GNSS modular receiver, a connected base station for use in civil construction, geospatial and agricultural applications. The R750 provides improved base station performance, giving contractors, surveyors and farmers reliable and precise positioning in the field.

The Trimble R750 utilizes a single Maxwell 7 ASIC with 336 GNSS tracking channels and offers all GNSS constellations plus the latest signals (such as GPS L1C and BeiDou-III). Featuring a built-in 4G LTE modem, Wi-Fi, Bluetooth and Ethernet, the Trimble R750 can broadcast RTK corrections to rovers via the internet, such as receiving corrections from an NTRIP base station or VRS network. It also easily connects to the receiver Web User Interface to configure settings and functions, like GNSS data logging.

The R750 can broadcast real-time kinematic (RTK) corrections for a wide range of applications, including seismic surveying, monitoring, civil construction, precision agriculture and more. Access to all available satellite signals provides improved performance and reliability when used with a Trimble ProPoint GNSS rover. ProPoint gives users improved performance in challenging GNSS conditions.

Key users in geospatial will include:

  • Land surveyors in the areas of cadastral, topographic, construction, pipeline and mine, typically using the Trimble R750 as a base station.
  • Geodetic surveyors, including national and state mapping agencies working on static observation campaigns for projects like geoid slope validation surveys and crustal movement monitoring, and Departments of Transportation (DOTs) doing control network surveys for road and rail.
  • Seismic surveyors doing natural resource exploration via a vehicle-mounted rover system and often operating in remote and wooded locations.

Featuring a built-in LTE modem, the R750 can provide corrections via the internet, making it easier to extend the range of a base station anywhere with cellular coverage. The built-in modem also provides remote access and management, delivery of email alerts and notifications, and data transfer capabilities between the field and the office.

“The ability to manage the base station remotely and to receive status notifications about the unit while in the office reduces downtime and the need to travel to the site,” said Scott Crozier, vice president of Trimble Construction Field Solutions.

Combined with Trimble 4D Control real-time monitoring software, users can capture high-frequency 3D positions for alarming and reporting on movement. The R750 offers multiple communication methods that provide flexibility for customers on how they deploy their monitoring system.
