ER-MA-04 Drone Antenna
Introduction
ER-MA-04 Drone Antenna is a high performance GNSS antenna designed for high precision positioning service and offers superior satellite signal tracking, including GPS, GLONASS, GALILEO and BeiDou. Its RTK level positioning accuracy makes it ideal to be integrated into application as surveying and mapping, and various UAVs operations.
Features
Advanced D-QHA Technology: Harxon’s D-QHA technology ensures ER-MA-04 more stable performance of wide-angle circular polarization (WACP), and smaller antenna phase center deviation (PCV).
Tracking in Challenging Environments: ER-MA-04 is able to track visible satellites under challenging conditions, providing the positioning solutions with high precision and reliable data.
Strong Anti-interference Performance: The antenna LNA features excellent out-of-band rejection performance, which can suppress the interference of magnetic disturbance, providing the stability and reliability of GNSS signals.
Small Size and Light Weight: The light weight and small size ER-MA-04 can lighten the loads of UAVs, as well as a standard SMA male connector for easy integration. Its IP67 ruggedized design can protect it from dust and water.
