Overview

The BRx7 is Carlson’s all-new multi-GNSS, multifrequency smart antenna. The BRx7 provides robust performance and high precision in a compact, rugged package with tilt compensation ability. With multiple wireless communication ports and an open GNSS interface, the BRx7 can be used in a variety of operating modes.

Use the BRx7 as a precise network rover to work with your GNSS VRS network, or set up your BRx7 as an easy-to-use base-rover package with industry-leading performance via the internal long range and spread-spectrum radio or cellular communication via Carlson’s Listen-Listen, a unique cloud- based low latency service that eliminates baseline length restrictions of UHF radios. With only an Internet connection, you can enjoy a simple, easy-to-use base-rover solution that can also support a single base with multiple simultaneous rover connections.

The BRx7 provides state-of-the-art RTK performance when receiving corrections from a static base station or network RTK correction system. With multiple connectivity options, the BRx7 allows for RTK corrections to be received over radio, cell modem, Wi-Fi, Bluetooth, or serial connection. The BRx7 delivers centimeter-level accuracy with virtually instantaneous initialization times and cutting edge robustness in challenging environments.

The BRx7 also features proprietary SureFix® technology to provide high fidelity information about the quality of the RTK solution, allowing enhanced and improved RTK accuracy, availability, and precision.

The built-in web user interface (WebUI) can be used to monitor and control the receiver status and operation, as well as to upgrade the BRx7 with new firmware and activations. The BRx7 is immune from magnetic interference, and is both Athena™ -enabled and Atlas®-capable (subscription required).

  1. Depends on multipath environment, number of satellites in view, satellite geometry, and ionospheric activity
  2. Depends also on baseline length
  3. Requires a subscription from Hemisphere GNSS
  4. Higher error can be observed in the GPS RTK solutions with tilts over 30°
