The SX3 architecture represents a new generation of MEMS inertial sensing, combining ultra-low noise, high stability, 600 Hz bandwidth, 10 kHz output rates and sub-20 µs latency in a compact platform. Designed for advanced stabilization, tracking, autonomy and navigation-assisted applications, SX3 demonstrates how modern MEMS technology is evolving beyond traditional motion control toward systems where measurement quality itself becomes a critical factor in overall mission performance.
