Introduction

ER-MA-01 GNSS Survey Antenna

ER-MA-01 GNSS Survey Antenna is a high performance multi-feed survey grade 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 of Survey Antenna

High phase center stability: a multi-point feeding design to achieve greater phase center stability. It effectively improves measurement accuracy and provides better RTK solution.

Tracking in Challenging Environments: The ability to receive low elevation signals with high gain and wide beam width makes ER-MA-01 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.

Ruggedized Protection: The light weight and small size ER-MA-01 Survey GNSS Antenna can lighten the loads of small unmanned vehicles, as well as a standard TNC female connector for easy integration. Its IP67 ruggedized design can protect it from dust and water.

GNSS Antenna Application Area

ER-MA-01 Survey Antenna covers the four-star multi-frequency external flying saucer antenna of GPS L1/L2/L5, GLONASS L1/L2/L3, BDS B1/B2/B3, GALILEO E1/E5a/E5b/E6, SBAS L1/L5 QZSS L1/L2/L5/L6, IRNSS L5, L-Band which meets the needs of multi-system compatible and high-precision users of current GNSS measuring equipment. It is widely used in geodesy surveying, navigation surveying, navigation, precision agriculture and marine surveying. It can also be applied to the military field according to the application conditions.
