Overview
The Beitian BT-722 is a GNSS timing antenna designed for satellite navigation positioning with broadband, anti-interference performance and out-of-band suppression. It supports multi-constellation, multi-band reception for high-reliability field deployments such as surveying, mapping, and precision agriculture.
Key Features
- Multi-constellation / multi-band support: GPS L1/L2/L5; BDS B1I/B2I/B3I/B1C/B2a/B2b; GLONASS L1/L2/L3; GALILEO E1/E5a/E5b/E6; SBAS L1/L5; QZSS L1/L2/L5/L6; IRNSS L5
- Multi-feedpoint symmetric antenna structure: very stable phase center; reduces antenna measurement error
- Interference suppression: anti-multipath chokes and wave-proof barrel design to suppress strong out-of-band interference and improve reliability
- High gain / low VSWR: improved low-elevation signal reception performance
- Outdoor-ready structure: IP67 waterproof grade; PC material designed for watertight performance and anti-discoloration for long-term outdoor use
- Lightning protection: YES
