In the context of inertial navigation, attitude refers to the orientation or position of an object relative to a reference frame, typically the Earth or a local coordinate system. It is defined by the object’s roll, pitch, and yaw angles, which describe its orientation in three-dimensional space.
Key Aspects of Attitude in Inertial Navigation:
Attitude Angles:
Roll: The rotation of the object around its longitudinal axis (typically the x-axis). It defines the object’s tilt to the left or right.
Pitch: The rotation around the lateral axis (typically the y-axis). It defines the up-and-down tilt of the object.
Yaw: The rotation around the vertical axis (typically the z-axis). It defines the object’s direction of travel or heading.
