The Carlson BRx6 Receiver

The Carlson BRx6 has been Bench-Mark’s best-selling surveying receiver for the past three years. This is the best all around piece of equipment we have to offer here at Bench-Mark. This is the receiver that has all of the features of the highest end GNSS manufacturers at a price that is actually reasonable. There is no need to pilfer your coffers in order to pay for this unit. The BRx6 is designed to quickly pay itself back, and is designed to last you for years to come. This is the network rover that will keep you ahead of the competition for years to come.


Multi Constellation GNSS and Triple Frequency

The BRx6 is Carlson’s multi-GNSS, multi-frequency smart antenna. With the Carlson BRx6 you receive corrections from; GPS, GLONASS, Galileo, BeiDou, and SBAS constellations at no extra charge. There is no need to activate the extra satellite constellations, they all come standard with the Carlson BRx6. To add to this, the BRx6 is also triple frequency. With a triple frequency receiver you have access to the most powerful GNSS signal yet L5. The L5 signal allows you to get performance otherwise impossible with traditional signals, in canopy positions. The L5 signal is powerful enough to get through tree canopies, allowing you to get shots that you would otherwise not have been able to get.


Surveyor Tough

The BRx6 provides robust performance and high precision in a compact and rugged package. With a surveyor tough aluminum body, the BRx6 is built to withstand whatever conditions you throw at it. The BRx6 is built to survive a 2 M pole drop. This is the receiver that is built with accidents in mind, and is built to survive them. The IP67 environmental rating means that Hemisphere’s BRx6 can withstand whatever conditions you face on site. This is the receiver that is built to last for years to come, and has the technology to compete that long as well.


Athena RTK Engine

The BRx6 also boasts the impressive SureFix technology. With SureFix, you can always be assured that the solution you are seeing is the true solution. While determining a a SureFix solution, the Carlson BRx6 runs two solutions in parrellel on the board level. It is doing the equivalent of recording a fixed solution, and dumping the antenna to determine if the fixed position is consistent. You can be assured that a SureFix solution is correct 99.9 % of the time. This is the data you can rely on every time.


Atlas L-band has the following benefits:

  • Positioning accuracy – Competitive positioning accuracies down to 2 cm
    RMS in certain applications.
  • Positioning sustainability – Advanced position quality maintenance in the
    absence of correction signals, using Hemisphere’s patented technology.

Powerful Communication

The BRx6 features the ability to send and receive corrections over both cell and UHF modems. The powerful 1 W internal Satel radio is one of the best in the industry. With an optimal range of 10 km, you barely have the need for an external base radio. This is the receiver that has the radio power to get every survey done. In fact the BRx6’s internal Satel radio is the best performing radio on Bench-Mark’s Range Test Baseline. Over 3.5 km with no line of site, the internal radio of the BRx6 has no issues receiving corrections and calculating a fixed position. Once we step out of the truck, the receiver nearly instantly fixes. Every other receiver we have tested on this baseline, has had some range issues. This is the ultimate internal radio.


The internal 4G cell modem also allows you to send and receive corrections over cell. The BRx6 is one of our favourite receivers to use on our own StormCaster internet RTK service. With StormCaster you can set up a permanent base at the office and as long as you have cell service, survey with unlimited range. With an internal cellular modem, you can run an an unlimited amount of rovers of the same base at multiple different job sites.


On top of the above mentioned communication options, the BRx6 also broadcasts a Wifi signal over which setup and updates can be applied. With the Web-UI you can quickly set up static data, a base and a rover with little to no hassle. This is the receiver that has an option for any kind of way you want to work.
