Product Description:

GNSS Reference Station Antenna

EV004

Description

The EV004 is a multi-system full-frequency reference station antenna that is capable of covering BDS, GPS, GLONASS and GALILEO. It has been designed with a unique choke structure, which gives it a number of notable characteristics. These include a stable phase centre, an effective multi-path suppression effect, high positioning accuracy and good low elevation angle reception.

Technical Features

1. The phase centre accuracy is of the order of a few micrometres, the stability is high, and the repeatability is good.

2. The item is of a diminutive size and possesses a lightweight structure.
3. The apparatus features a distinctive choke and choke plate configuration that exhibits an exemplary multi-path suppression effect.
4. The device exhibits high gain at low elevation angles and demonstrates robust satellite tracking capabilities.

5. The device is rated IP67, which indicates that it is waterproof and dustproof, and therefore suitable for use in outdoor environments for extended periods of time.

Application
• Survey and mapping	• Earthquake monitoring
• Bridge deformation monitoring	• Automatic operation of docks
• Global navigation satellite system reference
