Overview
HX-MR405A is a new-generation housed multi-band, multi-constellation full-frequency smart antenna supporting BDS, GPS, GLONASS, Galileo, and QZSS. Integrating Harxon’s industry-leading GNSS antenna technology with Unicore’s full-constellation, full-frequency RTK positioning module UM980, the HX-MR405A combines the GNSS antenna and module into a compact and ruggedized enclosure, delivering reliable and precise positioning performance. It supports single point meter level accuracy, DGPS sub-meter level and RTK centimeter/millimeter level accuracy, making it highly suitable for applications requiring high-precision navigation and positioning, such as precision agriculture, construction machinery, machine control, and autonomous mining trucks.

Integrated Design and Compact Form Factor
HX-MR405A integrates the high-precision GNSS antenna and module into a single compact unit, ensuring excellent compatibility between the antenna and module while simplifying system integration and reducing development costs for engineers.
Ruggedized GNSS Antenna with High Phase Center Stability
The main part of HX-MR405A is a ruggedized GNSS antenna designed for tough environments. It offers full support for reliable and consistent satellite signals tracking, including GPS, GLONASS, Galileo and BeiDou, QZSS.
High Performance RTK Positioning Module
HX-MR405A is integrated with Unicore’s full-constellation full-frequency RTK positioning module UM980, which integrates RF, baseband and high precision algorithm. It can simultaneously track multiple frequencies of all GNSS systems.
Strong Anti-Interference Performance
The antenna equips a robust pre-filtered LNA to minimize de-sensing from high level out-of-band signals, and restraints possible electromagnetic interferences, offering strong anti-interference performance for consistent and reliable GNSS signals.
