The Carlson BRx7 is a GNSS RTK receiver that delivers high precision and performance while being durable and compact.

The BRx7 has many communication options. Equipped with a GSM LTE modem, the receiver is ideal for working with VRS reference station networks with an accuracy of 8mm + 1ppm horizontally and 15mm + 2ppm vertically, and the built-in dual-band UHF radio enables base-rover measurement true GSM coverage. is missing. BRx7 also provides Carlson listen listen, a unique service that eliminates the uhf baseline length limit.
