Stonex SA1800 GNSS Antenna

Stonex SA1800 GNSS Antenna – High-Precision 3D Choke Ring Antenna

The Stonex SA1800 GNSS Antenna is a high-performance geodetic antenna engineered to deliver superior multipath mitigation and sub-millimeter phase center stability across all GNSS frequency bands, including L-Band. Its 3D choke ring design makes it ideal for mission-critical applications such as CORS (Continuously Operating Reference Stations), deformation monitoring of bridges and buildings, geological and structural monitoring, and other precision surveying tasks.

Key Features of Stonex SA1800 GNSS Antenna

3D Choke Ring Design: Offers excellent reduction of multipath errors across all GNSS bands, enhancing precision and repeatability of measurements.

High Phase Center Stability: Sub-millimeter stability ensures consistent phase center performance essential for long-term monitoring and control networks.

Wide Signal Tracking: Strong ability to receive low-elevation satellite signals with high gain and wide beam width for robust performance in obstructed environments such as tree lines and urban construction zones.

Strong Anti-Interference Performance: Low-noise amplifier (LNA) with excellent out-of-band rejection suppresses electromagnetic interference (EMI) and maintains stable GNSS signal reception even near power grids, base stations, and radio modems.

Rugged and Weatherproof: IP67-rated enclosure made from Glass Fiber Reinforced Polymer (GFRP) protects internal components from dust and water intrusion for dependable outdoor use.

Global Constellation Support: Designed to track all major GNSS constellations including GPS, GLONASS, BeiDou, Galileo, and SBAS, enhancing performance for reference station workflows.

Applications of Stonex SA1800 GNSS Antenna

Reference Station Networks (CORS): Provides stable and accurate observations for permanent GNSS reference networks.

Structural & Infrastructure Monitoring: Used for monitoring deformation and movement in bridges, buildings, dams, and other critical structures.

Geoscience & Geological Surveys: Ideal for long-term geodetic and tectonic monitoring applications.

Precision Surveying: Enhances RTK and post-processed kinematic (PPK) workflows in survey operations, especially in challenging environments.
