QUESCAN 40dB HG-GOYH7061 RTK GPS GNSS Antenna L1 L2 L-band 1575.42MHz 1227.6MHz GPS Antenna for Agricultural Surveying CORS

Overview

QT170(HG-GOYH7161) can receive signals in GPSL1/L2 BeiDouB1/B2/B3 GLONASSG1/G2 GalileoE1/E2b L-band. 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.
This RTK GNSS antenna supports four stars and nine frequencies. This product can be directly used on RTK equipment (no matter which brand), and is widely used in CORS base stations, geodetic surveying, high-precision positioning, agricultural machinery, autonomous vehicles, etc.

Key Feature

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
