Benefits and Uses of the Carlson BRx7 GNSS Receiver

Architects, engineers, and developers require tools to help them gather information to establish property lines and create maps. But not all devices deliver the required accuracy.

The advent of GPS technology, particularly the GNSS, made the survey process more efficient and accurate to the benefit of the mapping and surveying sector.

Global Navigation Satellite System technology has been making significant strides, and it now offers a navigation system that can work in any location without limitations. The system uses satellite signals to gather location information on Earth’s surface for different applications.

For the best results in specific projects, surveyors utilize 3 techniques of GNSS measurement with multiple processes: real-time kinematic (RTK) observations, static GNSS baseline, and continuously operating reference stations (CORS).

But as it is in every market, some products are superior to others: not all GNSS systems are made equal. Some, such as the Carlson BRx7 GNSS Receiver, are more advanced and well-equipped for the job.

But what makes the BRx7 GNSS Receiver the best in its class?


Stringent precision approaches in all stages of flight are not usually achievable with most GNSS systems in the market. This is where augmentation systems, such as the ones used by the Carlson BRx7 GNSS Receiver, prove useful.

Real-time kinematic (RTK) augmentation can achieve sub-decimeter level accuracy through multi-frequency GPS, Galileo, and GLONASS.

As a result, the benefits in multi-constellation surroundings are numerous. Users enjoy continuity, reliability, high signal-to-noise ratio, and multipath errors mitigation.

BRx7 guarantees better accuracy and reliability through the GNSS engine and SureFix. Other benefits include improved availability, RTK accuracy, and reliable precision.

The SureFix processor uses various inputs to weigh and provide the right RTK solution in environments near or under canopies.


Carlson is an intuitive and familiar software without a steep learning curve. The Carlson BRx7 receiver is lightweight, and you can use it as a base to send corrections to GNSS Rovers, RTK UAVs, or use it as a rover.

The receiver has dual removable batteries and an excellent user interface. It has various LEDs for Bluetooth, Data Link, satellite, and power. This makes it easy to operate.

Software updates can be through any WiFi-capable device such as tablets and smartphones.

Wireless Connectivity

The Carlson BRx7 boasts an integrated Quad-Band GSM, dual-band UHF transceiver, Bluetooth and Wi-Fi.

The receiver comes with Carlson Listen-Listen ready for an over-the-cloud correction. This is through a cellular data network for those that use BRx7 as the base station. The cloud-based service circumvents the distance limitations of UHF radios.

But that doesn’t mean the UHF radio signal is not good. In contrast, it is the best in its class in terms of range and spread spectrum.

Listen-Listen has RTK drone support and can manage multiple rover connections.

Cost-Friendly Surveying

GNSS RTK gives a centimeter-level accuracy and eliminates investing in additional infrastructure. Establishments such as forestry and park management will sometimes need to survey utility infrastructures or GIS and thematic mapping. Carlson is EGNOS ready to cut the cost of surveying.


GNSS technology has the potential to reduce project timelines for almost any project.

In many cases, one surveyor using GNSS-capable technology can function faster and complete tasks at double the speed of two or three workers using an obsolete surveying method.

And since more can be done in the same amount of time, users will be able to increase the size of the project. They can use the Carlson BRx7 technology and conduct surveys over greater distances and more extensive swathes of land.

Smaller crews and faster workflows translate to savings—the more the savings, the better the profit margin for the organization.


With a tilt compensation ability, a housing rated at IP67, and rugged construction, the Carlson BRx7 is perfect for the remote outdoors. But that’s not all.

It comes with 8GB of memory to support its functionality and has more than 800 channels. The memory is expandable to 32 GB with an SD card.

Athena GNSS engine RTK performance is the best in its class for mapping, construction, engineering, and topographic surveys.

BRx7 also uses Amazon Web Services for unlimited bandwidth, speed, and processing power and has a working time of up to 12 hours.

Carlson BRx7, The Best in Class GNSS Receiver

Once you decide to join the party of those enjoying the benefits of GNSS technology in surveying and mapping, you need a device you can rely on. The Carlson BRx7 has the connectivity, performance, speed, and accuracy required in your next topographic and engineering Surveys, Construction, Mapping, and GIS project.
