CW-NFS1340
MEMS North Seeker
Product Overview
CW-NFS1340 is a high-reliability, cost-effective six-axis MEMS inertial sensor. The module internally compensates full-temperature parameters including zero bias, scale factor, non-orthogonality error and acceleration-related terms, maintaining high measurement accuracy for a long time. Adopting integral vibration reduction and sealing design, it is widely applied in navigation, control and measurement fields represented by inertial navigation and attitude stabilization.
Core Advantages
High performance, compact size, light weight and low power consumption. Full-temperature calibration and compensation from -45℃ to +80℃. Supports automatic zero-speed correction to maintain azimuth accuracy. Supports component zero-bias calibration function. 100% domestically sourced components. 4kHz high-speed sampling. Resistant to harsh mechanical environments.
