Overview

Beitian BT-564 is a foldable quadrifilar helical GNSS antenna with an SMA-J connector, designed for RTK/UAV navigation and other GNSS positioning receivers that need stable multi-constellation signal reception in a compact form factor. It supports GPS, BDS, GLONASS, GALILEO, SBAS, QZSS, and IRNSS signal bands and provides 360° horizontal coverage.

Key Features

  • Foldable design (up to 90°) to reduce volume
  • Multi-system, multi-band reception: GPS L1/L2/L5; BDS B1/B2/B3; GLONASS L1/L2/L3; GALILEO E1/E5a/E5b/E6; SBAS L1/L5; QZSS L1/L2/L5/L6; IRNSS L5
  • 360° horizontal coverage angle
  • Right-hand circular polarization
  • Low power consumption: operating current <50 mA (3.3–12.0 V)
  • Compact and lightweight: antenna weight ≤28 g
