Description

The AT600 Choke Ring Antenna is a high-performance, full-constellation GNSS antenna designed for demanding geodetic, surveying, and CORS (Continuously Operating Reference Station) applications. Built with a state-of-the-art choke ring structure, it offers exceptional multipath suppression and delivers sub-millimeter phase center accuracy, making it ideal for long-term, high-precision positioning tasks.

Engineered to support all current and future GNSS signals—including GPS, GLONASS, BeiDou, Galileo, QZSS, and L-Band—the AT600 ensures maximum satellite compatibility and signal reliability. Its robust design and IP67-rated housing protect it in the harshest environments, including extreme temperatures, high humidity, and rough field handling.

Whether you’re establishing a reference station, conducting high-accuracy deformation monitoring, or supporting precision agriculture, the AT600 offers unmatched stability, signal tracking, and durability.

Key Features

• Full-Constellation Support: Tracks GPS, GLONASS, BeiDou (BDS), Galileo, QZSS, SBAS, and L-Band signals.

• Sub-Millimeter Accuracy: Delivers ultra-stable and repeatable measurements with minimal phase center variation.

• Choke Ring Design: Advanced 3D choke ring structure minimizes multipath effects and enhances signal purity.

• High Gain with Low Noise: Built-in low-noise amplifier (LNA) provides ≥50 dB gain and ≤1.8 dB noise figure.

• Excellent Low Elevation Reception: Maintains strong signal tracking even when satellites are near the horizon.

• Rugged & Weatherproof: IP67-rated casing, operational in –40°C to +85°C temperatures, with 95% humidity tolerance.

• Standardized Calibration: Phase center calibration meets IGS and NGS standards for professional surveying.
