Full constellation tracking and enhanced web capabilities in an ultra-compact package

Don't be fooled by its small size. The B125 packs in futureproof tracking of GPS, GLONASS, Galileo and BeiDou signals with the ability to perform centimeter-level RTK positioning all while being remotely accessed over Ethernet.

The B125 GNSS receiver board is an ultra-compact positioning engine capable of providing scalable positioning from sub-meter DGPS positioning to sub-centimeter RTK positioning. Low power consumption, comprehensive communication interfaces and peripheral support make the B125 extremely flexible and easy to integrate into any precise positioning application.
