Overview

This antenna is a full-band 3D chokecoil antenna covering GPS L1/L2, Beidou II B1/ B2/ B3, GLONASS L1/L2 and Galileo E1/E2/E5a/E5b/E6, which meets the networking requirements of CORS reference station and CORS reference station of the current GNSS measurement system. International advanced 3D structure choke design, equipped with anti-multi-path choke plate, waterproof, anti-UV cover, with stable phase center, high positioning accuracy, low elevation signal reception and so on.

Key Features

Full-band ：

GPS L1/L2/L5、BDS B1/ B2/ B3、GLONASS L1/L2、Galileo E1/E5a/E5b/E6、L-band

Strong anti-interference

performance

The pre-filtering scheme is

adopted to effectively suppress out-of-band interference

RTK positioning

accuracy

Multi-feed point design and symmetrical antenna structure are adopted to realize the

coincidence of phase center and geometric center, and

reduce the influence of antenna on measurement error.

Good reliability：

Lightning and waterproof design
