Carlson Software is now offering its next-generation multi-frequency, multi-GNSS BRx7 smart antenna.

The BRx7 is a full redesign of Carlson’s flagship GNSS receiver, delivering high-level specifications, performance and value for surveyors, contractors, engineers and GIS professionals.

Weighing 2.8 pounds with batteries, the BRx7 saves time and increases productivity by accurately compensating for tilt. It comes standard with dual, hot-swappable batteries for 11+ hours of uninterrupted efficiency. The BRx7 provides 800+ channels, 8gb of memory, and is designed with a rugged, compact IP67-rated housing.

Best-in-class RTK performance is provided by the Athena GNSS engine, supporting multi-frequency GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS and Atlas L-band capability. In addition, the BRx7 uses proprietary SureFix technology to provide a high-fidelity quality indicator of the RTK solution, allowing users an extremely high confidence in their current accuracy.

The BRx7 provides RTK baselines up to 50 km with fast acquisition times when used with Carlson Listen-Listen, as well as UHF, spread spectrum, cellular, Bluetooth and Wi-Fi wireless communication.

Well-suited to a variety of operating modes, the BRx7 can be deployed as a powerful base with additional access to BeiDou phase 3 satellites in a base-rover setup, or as a lightweight, powerful network rover.

“The BRx7 represents the next generation of GNSS technology,” said Butch Herter, Carlson’s director of hardware development. “Through this total redesign in partnership with our manufacturer, Hemisphere GNSS, we’ve brought the technology and functionality above the competition while retaining the ease-of-use, durability, and superior support that Carlson is known for.”

The smart antenna comes with a dual-band radio module that is capable of both 400 MHz and 900 MHz operation. This allows for the long range capability of the UHF 400 MHz signal plus the ability to switch to the 900 MHz frequency-hopping spread spectrum (FHSS) signal for better performance in noisy radio environments.

The BRx7 introduces a new INS-based sensor-fusion platform to support enhanced tilted pole measurements for land survey applications. This new design allows for easy calibration, is immune to magnetic interference, and is extremely reliable in virtually any environment.

“The BRx7 represents the advanced technology, durability, and ease-of-use that our customers have come to expect,” said Bruce Carlson, founder and president of Carlson Software. “By redesigning this system from the ground up, we are offering our customers both unparalleled performance and versatility, but also a value that’s unbeatable in the market today.”
