Overview

QT151 can receive signals in GPS, Galileo and Beidou frequency bands. The antenna has the characteristics of high gain, good low elevation angle gain,wide-angle circular polarization and stable phase center.
Widely used in fields such as autonomous driving, high-precision agriculture, surveying, geodesy, etc., it can replace Trimble AG15/15/35 series GNSS antenna and is compatible with multiple devices such as Trimble CFX/FM750.

Key Features

The antenna part adopts a multi-feed point design scheme to ensure the coincidence of the phase center and the geometric center, and minimize the influence of the antenna on the measurement error；

The antenna unit has high gain and beam width in the pattern to ensure the receiving effect of low-elevation signals, and it can still search satellites normally in some severely occluded occasions；

Anti-high and low temperature impact, waterproof, and UV protection cover, which provides protection for the antenna to work in the field for a long time.
