📌 Overview
The BK-S65 All-in-One Miniaturized GNSS Anti-Jamming Module is a highly integrated GNSS protection terminal designed for small and medium-sized UAV platforms and other industrial applications requiring reliable positioning under complex electromagnetic environments.
With its 65mm array antenna, compact design, and low power consumption, this module provides effective wideband interference suppression and stable satellite navigation performance for B1/L1 frequency signals.
It integrates an antenna array, anti-jamming circuits, and a GNSS navigation receiver into one lightweight unit, achieving miniaturization, cost efficiency, and easy installation for UAV and robotic systems.
