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 GNSS Helical 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
