T/CI 064-2022 General Guidelines for Airborne Inertial Navigation Systems

Scope

Main technical content: 1. **Inertia**: The inherent property of an object to maintain its state of motion without change. 2. **Inertial Navigation**: An autonomous navigation system that uses inertial sensors to establish a directional reference and measure the acceleration of the vehicle to automatically calculate its instantaneous speed and position. 3. **Inertial Surveying**: A measurement system that uses the orientation maintained by inertia and the detected acceleration to determine the attitude and position of the vehicle. 4. **Navigation**: The process of guiding a vehicle to a predetermined destination. 5. **Navigation Parameter**: A parameter used to characterize measurable motion or position during navigation. 6. **Roll Angle**: The angle between the horizontal plane and the vehicle's lateral axis. 7. **Pitch Angle**: The angle between the vehicle's longitudinal axis and the horizontal plane. 8. **Yaw Angle**: The angular displacement of the vehicle's longitudinal axis relative to a predefined heading within the horizontal plane. 9. **Inertial Navigation System (INS)**: An autonomous navigation system that uses inertial sensors, a directional reference, and initial position information to determine the attitude, position, speed, and acceleration of the vehicle. 10. **Initial Alignment**: The process of determining the relationship between the input axis of the inertial sensors and the coordinate system used by the inertial navigation system. **Technical Requirements**: 4.1. **Qualification Assessment**: The devices submitted according to this guide should be products that have passed qualification assessment or been approved. 4.2. **General Requirements**: The inertial navigation device should be completely independent and autonomous, unaffected by external electromagnetic interference, and capable of continuously providing position, velocity, and attitude information. The device consists of basic components and customized comp
