Overview

Beitian BT-7112 is an RTK GNSS multi-frequency antenna designed to simultaneously receive GPS, GLONASS, Galileo, and BDS (BeiDou) signals. It is positioned as a four-system, multi-band antenna for high-precision surveying/mapping and other applications requiring stable signal reception.

Key Features

  • Multi-constellation, multi-band reception: GPS L1/L2, GLONASS G1/G2, GALILEO E1/E5b, BDS B1/B2/B3.
  • Polarization: RHCP; horizontal coverage: 360°.
  • Multi-feed point design to improve phase center and geometric center coincidence and reduce measurement error.
  • Lightning protection design inside the antenna (as described in the product material).
  • High LNA gain: 38±2 dB; low noise figure: ≀2.0 dB.
  • IP67 ingress protection for outdoor deployment.
  • Mechanical design includes four product fixing screw holes and silicone seals (as described in the product material).
