丨 Product Introduction
AK411 It features high gain, low SWR, low noise figure for sub-meter precision positioning, plus compact size, easy integration, good stability and weather resistance. Adopting right-handed circular polarization for strong anti-interference, it is widely used in vehicle positioning, intelligent transportation, mechanical control, deformation monitoring, GIS and surveying.
Product Features:
1. Signal Processing: L1 band support, sub-meter accuracy, high weak-signal sensitivity, built-in LNA noise reduction for precise positioning.
2. Compatibility: Multi-satellite system (GPS, BeiDou, etc.) L1 signal support, stable reception in complex scenarios, improved positioning reliability.
3. Physical Characteristics: Compact & easy-integrated, stable ceramic build, temp/water/dust-proof, anti-electromagnetic interference, reliable in harsh environments.
4. Flexible Adaptation: Customizable structural parameters, stable performance, long lifespan, low long-term cost.
5. High Frequency Stability: Stable L1 signal reception amid temp/humidity changes, anti-frequency drift, sustained sub-meter positioning accuracy.
