Introduction

HX-MR401A is a housed multi-band multi-constellation smart antenna developed by Harxon. Combining Harxon’s world’s leading antenna technology with Unicore’s full-constellation full-frequency RTK positioning module UM980, HX-MR401A delivers precise positioning performance in a compact and integration-ready structure. it’s able to provide single point meter level accuracy, DGPS sub-meter level and RTK centimeter/millimeter level accuracy, very suited for various robotic lawn mower and unmanned aerial vehicle (UAV) applications

Key Features

Integrated Design and Compact Form Factor

The compact smart antenna with IP67 rated enclosure , weighing ≤40g and measuring Φ48*H38mm, greatly reduces the weight of UAVs and features low power consumption.
Precision-Tuned OEM GNSS Antenna

HX-MR401A is integrated with Unicore’s full-constellation full-frequency RTK positioning module UM980, which integrates RF, baseband and high precision algorithm.
High Performance RTK Positioning Module

Integrated with Unicore’s full-constellation full-frequency RTK positioning module UM980, which integrates RF, baseband and high precision algorithm, it can track multiple frequencies of all GNSS systems, enabling high-precision RTK positioning.
Strong Anti-Interference Performance

HX-MR401A equips a robust pre-filtered LNA that features an excellent out-of-band interference rejection performance, and the module features 60 dB narrowband anti-jamming and advanced jamming detection technology
