MEMS (Micro-Electromechanical Systems) refers to miniaturized sensors and mechanical components that are integrated into Inertial Navigation Systems (INS). MEMS-based IMUs (Inertial Measurement Units) use micro-scale gyroscopes and accelerometers to measure motion, orientation, and acceleration, making them ideal for drones, robotics, automotive, and portable navigation systems.
How MEMS Works in INS?
MEMS Gyroscopes – Measure angular velocity for tracking orientation changes.
MEMS Accelerometers – Detect linear acceleration, helping estimate velocity and position.
Sensor Fusion – MEMS IMUs integrate GNSS, magnetometers, and LiDAR to improve navigation accuracy.
Applications of MEMS in INS
✔ Drones & UAVs – Provides stabilization and motion tracking.
✔ Automotive & Robotics Navigation – Used in self-driving cars and robotic systems.
✔ Wearable & Portable Devices – Enables motion tracking in consumer electronics.
Advantages of MEMS-Based INS
✔ Compact & Lightweight – Perfect for size-constrained applications.
✔ Low Power Consumption – Ideal for battery-powered devices.
✔ Cost-Effective – More affordable than FOG or RLG-based INS.
Challenges of MEMS-Based INS
✔ Higher Drift & Noise – More prone to long-term errors compared to fiber optic gyroscopes.
✔ Limited Accuracy for Long-Duration Navigation – Requires frequent GNSS updates to maintain precision.
