Small board, full functionality

A compact, dual-frequency GNSS board

Product Info

"All-in-view" dual-frequency tracking

So much functionality in such a small package. The ultra-compact B111 GNSS receiver board is capable of providing scalable positioning from sub-meter DGPS to sub-centimeter RTK positioning. The lightweight board offers 226 universal channels for reliable, “all-in-view” tracking of GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS signals. The board’s flexible design—including its low power consumption, comprehensive communication interfaces and peripheral support—make it easy to integrate the B111 into any precise positioning application.

  • Compact, dual-frequency receiver
