AttitudeQuaternion class

The attitude in the aeronautical frame (right-handed, Z-down, X-front, Y-right), expressed as quaternion. Quaternion order is w, x, y, z and a zero rotation would be expressed as (1 0 0 0).

Properties

hashCode → int

The hash code for this object.

no setter, inherited

mavlinkCrcExtra → int

no setter, override

mavlinkMessageId → int

no setter, override

pitchspeed → float

Pitch angular speed

final

q1 → float

Quaternion component 1, w (1 in null-rotation)

final

q2 → float

Quaternion component 2, x (0 in null-rotation)

final

q3 → float

Quaternion component 3, y (0 in null-rotation)

final

q4 → float

Quaternion component 4, z (0 in null-rotation)

final

reprOffsetQ → List<float>

Rotation offset by which the attitude quaternion and angular speed vector should be rotated for user display (quaternion with w, x, y, z order, zero-rotation is 1, 0, 0, 0, send 0, 0, 0, 0 if field not supported). This field is intended for systems in which the reference attitude may change during flight. For example, tailsitters VTOLs rotate their reference attitude by 90 degrees between hover mode and fixed wing mode, thus repr_offset_q is equal to 1, 0, 0, 0 in hover mode and equal to 0.7071, 0, 0.7071, 0 in fixed wing mode.

final

rollspeed → float

Roll angular speed

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

timeBootMs → uint32_t

Timestamp (time since system boot).

final

yawspeed → float

Yaw angular speed
