Introduction

ER-MA-02 Universal Measuring Antenna

Introduction

ER-MA-02 Universal Measuring Antenna is a high performance survey GNSS antenna which offers superior satellite signal tracking, including BeiDou, GPS, GLONASS and GALILEO. It meets the requirements of high precision and multi-constellation compatibility. It enables easy and flexible installations (magnetic mount, screws mount and pole mount) for many high-precision applications.

Features

Ruggedized Housing, Easy to Install: It is designed with brand new structure, enabling easy and flexible installations (magnetic mount, screws mount and pole mount) for many high-precision applications.

High Phase Center Stability: features a multi-point feeding deign to achieve greater phase center stability. It effectively improves measurement accuracy and provides better positioning solutions.

Tracking in Challenging Environments: The ability to receive low elevation signals with high gain and wide beam width makes ER-MA-02 an excellent choice for tracking visible satellites under challenging conditions.

Strong Anti-interference Performance: The antenna LNA features an excellent out-of-band rejection performance, which can suppress the electromagnetic interference, providing the stability and reliability of GNSS signals.
