VLG WIRELESS TECHNOLOGY CO., LTD. Full band choke ring antenna VLG-CORS-R40QP

GPS L1/L2/L5,BDS B1/ B2/ B3, GLONASS L1/L2, Galileo E1/E2/E5a/E5b/E6

This antenna uses traditional 2D choke design, which cover full bands of 4 major satellite navigation systems. It has the satellite signal multipath effect suppression technology, which can reduce the influence of multipath effect on the measurement accuracy, and meet the current GNSS measurement system's CORS base station and CORS reference station networking requirements.

Description

Product Introduction:  

1. The antenna adopts multi-feed point design and a completely symmetrical antenna structure to realize the coincidence between the phase center and the geometric center, and reduce the influence of the antenna on the measurement error.  

2, The advanced 2D structure choke design, which equipped with anti-multipath choke plate as well as waterproof, UV-proof cover, with characteristics like stable phase center, high positioning accuracy, good reception effect at low elevation,  and so on.

3, The low noise part adopts the pre-filtering scheme to effectively suppress the out-of-band interference and improve the reliability of the system.  

4. The power supply circuit adopts lightning protection design, which can effectively protect the low noise amplifier and ensure that the antenna can still work normally in the outdoor harsh environment. 

5, Built-in voltage regulator circuit, antenna can work normally in a wide input voltage range.  

6. The radome is made of resin specially used for satellite antenna. The surface is resistant to salt fog and ocean atmosphere corrosion, which without obvious discoloration after 5 years under intense ultraviolet sunlight.
