Product Introduction
Universal Compatibility
Supports all major global navigation systems (GPS L1/L2/L5, GLONASS, Galileo, Compass B1/B2/B3) across 1197-1612MHz frequency range, ensuring global positioning coverage.
High-Sensitivity Performance
Integrated 38dB Low-Noise Amplifier (LNA) with <1.0 noise figure captures weak signals in challenging environments, while <2mm phase center stability ensures centimeter-level accuracy.
Superior Signal Quality
≤2.0 V.S.W.R and Right-Hand Circular Polarization (RHCP) minimize signal loss. Axial ratio ≤3 (at 90° elevation) and front-to-back ratio ≥15dB reject multipath interference.
Robust & Energy Efficient
Wide voltage input (3.3V-12V) and low current consumption (25-40mA) make it ideal for battery-powered field equipment like drones and portable devices.
Optimized Radiation Pattern
High gain (≥6dB at zenith, ≥0dB at 20° elevation) and wide ±60° coverage ensure consistent performance across varied installation angles and moving platforms.
Application scenarios
Precision Agriculture: RTK-guided tractors requiring multi-band correction
Surveying & Mapping: Base stations needing stable phase center for geodetic work
Marine Navigation: Sailboats in open water requiring GLONASS/Galileo coverage
Drone Operations: UAVs performing LiDAR surveys in urban canyons
IoT Trackers: Long-term asset monitoring with low power consumption
