Details
A compact, vehicle-ready full-frequency GNSS antenna designed for high-precision RTK positioning and measurement.
Full-frequency, multi-constellation reception helps reduce signal dropouts and improves positioning stability in complex environments.
Multi-constellation GNSS coverage supports more reliable satellite tracking for surveying, agriculture, and mobile applications.
Low-profile housing makes installation easier on vehicles, equipment, and other platforms where height matters.
UV-resistant materials and a built-in magnetic base support long-term outdoor use and quick temporary mounting.
Ideal for vehicle-mounted positioning, geodetic and channel surveying, precision agriculture, smart grid, and logistics.
