GNSS Antenna U-GGBG7151

Introduction

Introduction

Features

1.Using multi feed point design to ensure the superposition of phase center and geometrical center which could minimize the influence of measurement error to lowest range

2. High gain of the antenna element and the direction map beam width to make sure the receiving satellites performance of low elevation mask

3. Resistance multipath effects board inside could reduce the measurement error caused by multipath

4. Water proof, shock proof and lightning resistance

Application

Survey antenna is the traditional RTK product standard antenna, can be widely used in land survey, marine survey, channel survey, seismic monitoring, bridge survey, container operation, etc.
