Integrated Design and Compact Form Factor
The compact smart antenna weighs ≤80g and measures Φ90* H24.4mm, featuring stable structure, good consistency, and reliable electrical performance.
Precision-Tuned OEM GNSS Antenna
The main part of HX-ME402A is Harxon’s small size and high performance OEM GNSS antenna designed for high precision positioning. It excels in offering superior satellite signal tracking, including GPS, GLONASS, GALILEO, Beidou, QZSS and SBAS.
High Performance RTK Positioning Module
HX-ME402A is integrated with 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, enabling the module to output high-precision RTK positioning.
Strong Anti-Interference Performance
The antenna 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.
