Product Description

MG4N03A adopts a multi-feed point design to ensure the coincidence of the antenna phase center and the geometric center, providing measurement accuracy. Built-in low-noise amplifying module, using pre-filter and multi-stage filter to filter out interference signal, to ensure normal operation in harsh electromagnetic environment. Small size and light weight, effectively reduce the weight of the equipment.

Product Features

Product Advantages

Comprehensive GNSS support, including GPS, GLONASS, Beidou and Galileo
Robust low-elevation satellite tracking
Adopts multi-feed point design, ensures the performance of right-hand circular polarization and phase center, reduces the influence of measurement error
An internal multi-path-rejection board eliminatesmulti-path interference errors
High Gain, good reception for low-elevation satellite signals,ensure the signal can still be received normally in some severely occluded occasions
