Used Carlson BRx7

The Carlson BRx7 is offered as pre-owned surveying equipment, with condition options including Like New and Very Good, depending on availability. Used equipment is cleaned, inspected, tested, and calibrated before sale to verify that it operates within the expected specifications.

The listing offers several data collection configurations: BMT8 Android with FieldGenius, Mesa 4 with FieldGenius, Mesa 3 with Carlson software, or no data collector. You can also select a Base Accessory Kit, Rover Accessory Kit, or neither, allowing you to tailor the configuration to your existing field equipment.

Yes. The BRx7 can be configured as a base station, a rover, or a static GNSS receiver. Its internal UHF radio supports conventional base-and-rover RTK workflows, while its cellular connectivity provides another option for receiving or transmitting corrections.

Yes. The BRx7 supports NTRIP and network RTK workflows through its integrated cellular modem or a compatible external internet connection. You will need cellular or other internet access, along with credentials for a compatible correction service, to use network-based corrections in the field.

The BRx7 listing specifies an internal 1 W Satel radio with a range of up to 10 km. Actual base-to-rover distance depends on terrain, line of sight, antenna placement, interference, and radio configuration, so the maximum range should not be treated as a guaranteed working distance.

The BRx7 supports tilt compensation with a stated error of approximately 2 cm at pole tilts up to 30°, increasing to approximately 5 cm at tilts up to 60° when using a 1.8 m pole. These figures describe the specified tilt-compensation performance, so for measurements requiring the highest confidence, use the appropriate survey procedures and verify critical points independently.

The product listing specifies approximately 9 hours of operation with its hot-swappable battery setup. The receiver uses two removable batteries, allowing a depleted battery to be replaced while the other continues powering the unit; actual runtime depends on operating mode, radio and cellular use, and battery condition.

Yes. The BRx7 is compatible with Hemisphere’s Atlas L-band correction service, which receives corrections through satellite signals rather than relying on a local base station or cellular data connection. An appropriate Atlas subscription is required, and an active subscription or authorization should not be assumed to be included with a used receiver.

The BRx7 is designed to work with Carlson’s SurvCE and SurvPC field software, and the product listing also offers configurations with MicroSurvey FieldGenius. The specific controller and software combination matters, so choose the data collection option that matches your existing workflow or select a compatible controller and software package with the receiver.
