LKF-1400FA is an anti-interference GNSS receiver designed for
high-precision positioning applications in complex electromagnetic
environments. The product breaks through the anti-interference
bottleneck of traditional GNSS receivers by integrating advanced
interference identification and suppression algorithms, enabling
stable and reliable satellite positioning performance even in
strong interference, weak signal, and multipath environments. It is
suitable for a wide range of critical applications, including
navigation, telemetry, and time-frequency synchronization.
Building on the proven architecture of mature GNSS receivers, the
1400FA undergoes systematic optimization for anti-interference
capabilities, adopting a modular design philosophy for easy
integration and scalable deployment, offering exceptional
engineering practicality and cost-effectiveness.
