Product Introduction
Multi-System & Multi-Frequency Support
Compatible with GPS (L1/L2/L5), GLONASS, Galileo, and COMPASS (B2/B3), ensuring global signal coverage and adaptability for high-precision applications like UAV guidance and RTK surveying.
Advanced Spiral Design with Air Medium
Utilizes multi-arm spiral technology and air dielectric for high gain, stable phase center (<2mm error), and superior low-elevation satellite signal reception, ideal for obstructed environments.
Robust Durability
Features triple protective covers and IP67-rated construction, safeguarding against dust, water, and extreme weather conditions during fieldwork.
Low Noise & High Gain LNA
Integrated LNA with 38±2dB gain and <1.0dB noise figure enhances signal clarity, critical for precision tasks in remote or interference-prone areas.
Flexible Power & Customization
Operates on 3.3~12V DC with low current consumption (25~40mA), compatible with portable devices. Supports customization for specialized applications.
Application scenarios
UAV Navigation: Ensures centimeter-level accuracy for aerial mapping and drone-based inspections.
Portable RTK Surveying: Ideal for land surveyors requiring lightweight, high-precision equipment.
Disaster Response: Monitors terrain shifts in earthquake or landslide zones.
Precision Agriculture: Guides autonomous machinery for crop management.
Urban Infrastructure Mapping: Updates GIS databases with high-resolution data.
