Precise inertial sensors are vital for robust navigation, stabilization, and event detection in defense systems. Devices such as accelerometers and gyroscopes transform physical motion into digital signals. Advanced sensor fusion techniques combine this basic data from multiple inertial sources to enhance accuracy, stability, and position estimation. Building on this, Edge AI enables sensors to interpret data autonomously, adapt to dynamic environments, and make context-aware decisions. Microsystem technologies (MEMS) provide a crucial foundation: miniaturization enhances mechanical robustness, reduces power consumption, and allows high integrability into complex systems. MEMS sensors offer compact, adaptive, and reliable components that support resilient and sovereign sensing capabilities ...
