A gyroscope is a rotation-measuring sensor used in Inertial Navigation Systems (INS) to track angular velocity and determine an object’s orientation and movement. It is a key component of an Inertial Measurement Unit (IMU) and enables precise navigation in aircraft, ships, submarines, missiles, and autonomous systems.
How a Gyroscope Works in INS
Detects Angular Velocity – Measures the rate of rotation around an axis.
Calculates Orientation – By integrating angular velocity over time, the system determines roll, pitch, and yaw.
Assists in Dead Reckoning – Used alongside accelerometers to estimate position without GNSS.
Types of Gyroscopes in Inertial Navigation
Why Gyroscopes are Essential in INS
✔ Works Without GNSS – Used in submarines, missiles, and GPS-denied environments.
✔ Provides Stable Orientation Data – Crucial for flight control, navigation, and targeting systems.
✔ Integrated with IMU & INS – Combined with accelerometers and magnetometers for complete motion tracking.
