Carlson BRx7 GNSS Receiver

Carlson BRx7 GNSS Receiver

The BRx7 GNSS recevier from Carlson Software saves time and increases productivity by accurately compensating for tilt, and comes standard with dual, hot-swappable batteries for up to 12 hours of uninterrupted efficiency.



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 cloudbased 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

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.
