Overview

QT151 can receive signals in GPS, GLONASS, 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. It is suitable for the field of four-system, high-precision surveying and mapping, and is widely used in geodetic surveying, road construction, ocean surveying, terminal container operations and other occasions.

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.
