# `t`

```elixir
@type t() :: %Common.Message.AttitudeQuaternionCov{
  covariance: [Float32],
  pitchspeed: Float32,
  q: [Float32],
  rollspeed: Float32,
  time_usec: XMAVLink.Types.uint64_t(),
  yawspeed: Float32
}
```

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).
