Carlson BRx7

The Carlson BRx7 is the latest GNSS receiver from Carlson to powered by Hemisphere’s industry leading GNSS technology. The BRx7 takes everything that made the beloved BRx5 and BRx6+ receivers so great and improves upon those ideas. The hot swappable batteries and compact size were adopted from the BRx5 and further improved upon, while the robust RTK engine and great Satel radios were taken from the BRx6. Sporting the brand new Phantom P40 board from Hemisphere, the BRx7 offers unparalleled performance.


Tilt Surveying

The Carlson BRx7 finally allows for tilt shots while surveying, up to an angle of 30°. With a 30° internal tilt sensor, you can get shots you thought were otherwise impossible. Whether the point is under a vehicle or directly next to a building, you can tilt the receiver to an angle where it can see more of the sky, ensuring your accuracy. The internal tilt sensor in the BRx7 offers 2 cm of compensation at 30°. Never have the calibration of your pole impact your results again.

Used Equipment

All of our used equipment is rigorously tested to ensure that it meets our used equipment standards. Before the instrument is sold, we test to ensure that the instrument specifications are as expected, and any broken parts are replaced or refurbished. Our standard testing regiment includes a range test to ensure the radios of any GNSS receiver are still operating within specifications. Our test course is a 3 km in city range test with no line of sight. This ensures the test is as close to what you experience in the field as possible. For total stations, we ensure that the unit is within expected calibration by shooting multiple points, with both sides of the total station. If work is required, we have an optical expert take a look and adjsut the unit. 

Next we ensure that the instrument has the latest firmware and drivers available. This is to ensure that the unit is working as well as possible when you receive it. In order to repair used equipment, we keep a range of parts for all Hemisphere recievers, and many of the other leading brands. This allows us to repair and refurbish instruments that are otherwise not supported by the manufacturer. Finally, the units are thoroughly cleaned to ensure they look as new as possible.
