ER-MA-03 GNSS Measurement Antenna

Introduction

The ER-MA-03 GNSS Measurement 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. And it can be used with a variety of receivers, suitable for various occasions.

Features

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-03 an excellent choice for tracking visible satellites under challenging conditions.

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

Durable, Easy-installation design for Precision Applications: The compact and lightweight design makes ER-MA-03 highly portable and suitable for outdoor operating in precision applications. Its IP67 protection keeps ER-MA-03 from dust and water for quite a long time.
