Carlson BRX7 Base Receiver for Total Station Survey Equipment

The Carlson BRx7 GNSS Base Receiver is a compact, multi-constellation base station designed for total-station survey workflows, delivering high-precision RTK corrections to rovers or robotic total stations in the field. As a base or rover, it supports internal long-range and spread-spectrum radio, or cellular connectivity through Carlson's Listen-Listen cloud RTK service, enabling flexible correction paths and reducing baseline-length constraints compared with traditional UHF links. With multi-GNSS tracking and dual hot-swappable batteries, the BRx7 provides robust field performance and can operate for up to 12 hours on two 7.2 V, 3400 mAh packs. A built-in 4G LTE modem (nano SIM required) supports cellular corrections and remote data access, making it suitable for network RTK and cloud-enabled workflows in construction, mapping, and civil surveying.
