Choke Ring GNSS Antenna with Strong Multipath Suppression

GNSS Antenna

Choke Ring GNSS Antenna with Strong Multipath Suppression 

GNSS antenna for base station that covers comprehensive GNSS support: GPS, GLONASS, Galileo, BeiDou as well as L-Band correction service.The antenna part adopts a multi-feed point design and a completely symmetrical antenna structure to ensure that the phase center coincides with the geometric center and reduce the influence of the antenna on the measurement error. The choke coil design is used to achieve excellent multipath suppression and high phase center stability , Good repeatability; unique waterproof and dustproof design, to ensure that the core unit and components are completely sealed, to meet the complex outdoor environment, can work outdoors for many years.

Key Features

01

High Phase Center Stability

2018-07-16
The antenna part adopts a multi-feed point design and a completely symmetrical antenna structure, which has a relatively stable phase center and reduces the impact of the antenna on measurement errors.
01

Tracking in Challenging Environments

2018-07-16
2.The unique waterproof and dustproof design ensures that the core unit and components are completely sealed to meet the complex outdoor environment and can work normally outdoors all year round.
03

More Ruggedized for Long Lasting Durability 

2018-07-16
3.The IP67 ruggedized cover is made of Glass Fiber Reinforced Polymer(GFRP) material. The newly designed choke rings are treated with a more robust double treatment for longer lasting durability in harsh environments.
04

Strong anti-interference ability

2018-07-16
4.Adopting pre-filtering and multi-stage filtering scheme, it can effectively suppress out-of-band strong interference signals
