Introduction

HX-ME407A is a highly integrated high-precision RTK antenna, engineered to deliver exceptional positioning performance. It combines a multi-constellation, multi-frequency GNSS antenna (supporting BDS, GPS, GLONASS, Galileo, and SBAS), a high-performance RTK module, a 4G antenna, a 4G module, a LoRa antenna, a LoRa module, and an MCU within a compact enclosure. This all-in-one solution ensures robust system stability, significantly streamlines the integration process, and accelerates time-to-market. HX-ME407A is the ideal positioning and navigation solution for demanding applications such as precision agriculture, UAVs, and autonomous robotics.

Key Features

Integrated Design and Compact Form Factor

HX-ME407A features a highly integrated, all-in-one design that combines OEM GNSS antenna, RTK module, 4G antenna, 4G module, LoRa antenna, LoRa module, and MCU into a single unit.
Precision-Tuned OEM GNSS Antenna

The main part of HX-ME407A is an OEM GNSS antenna engineered for maximum precision and reliability. Its multi-feed design ensures a highly stable phase center coincident with the geometric center, which minimizes measurement errors.
Tracking in Complex Environments

The antenna delivers exceptional high-gain performance with minimal signal loss, ensuring reliable satellite signal tracking. Its wide beam width covers a broad frequency range with high marginal gain, maintaining robust signal availability even at low elevations.
Strong Anti-Interference Performance

The advanced LNA (Low Noise Amplifier) excels in improved signal filtering and out-of-band rejection and restraints unwanted electromagnetic interferences, plus strong multi-path reduction capacity over all GNSS frequency bands
