Description

This high-precision, low-profile external antenna is designed for advanced GNSS applications requiring centimeter-level accuracy and reliability. It supports multi-constellation and multi-band operation, making it ideal for demanding environments such as surveying, autonomous vehicles, smart farming, and GIS. The antenna is ground plane independent and features a pre-filter for enhanced signal quality, low power consumption, and a robust IP67-rated housing for outdoor use.
