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


The pre-filtering scheme is 

adopted to effectively suppress out-of-band interference

RTK positioning 


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
