Trimble R750 / R750-2 Help

Welcome to the Trimble® R750 / R750-2 GNSS Receiver Help.

The R750 and the R750-2 (also known as Model 2) modular GNSS receivers are ideal for the following site development and construction applications:

  • Base station for precision GNSS applications such as site positioning and machine control

  • Location RTK for site vehicle and supervisors

  • Precision RTK rover on-site

  • System integrator applications using Location GNSS augmentation, including RTX, OmniSTAR, Location RTK, SBAS, DGPS RTCM, and Precision RTK

The receiver has a keypad and display, so you can configure the receiver without using a controller or computer. The receiver can optionally record GNSS data to the internal memory, and transfer the data over a internal LTE modem, Wi-Fi, Bluetooth, serial, or ethernet connection.

The R750-2 receiver (available from end of May 2025 in select countries) has the following additional features:

  • Internal UHF radio:

    • Dual-band (selectable):

      • 410 to 475 MHz: Worldwide excluding S. Africa, Thailand, and UAE (depending on the local licensing) (P/N 218500-50).

      • 900 MHz: Fully integrated, internal 900 MHz radio; Tx/Rx 1 W transmit power (P/N 218500-50).

    • 450 MHz only (ETSI compliant for S. Africa, Thailand, and UAE):

      • 403 to 473 MHz (P/N 218500-40).

    • No UHF (P/N 218500-00).

  • Maxwell™ 7 technology dual-chipset for 672 tracking channels.

  • Worldwide 4G LTE modem with extended global carrier support.

For more information, see Standard features.

Unless otherwise noted, this information covers both receiver models.

The label on your receiver shows if you have an R750 or R750-2. P/N 118500‑xx is an R750. P/N 218500‑xx is an R750-2.
