Expand description
Read model of the navigation solution.
Estimator (state + covariance) or intake (last fix): displays, autopilots
and alarms need the same answers — position, speed, direction, uncertainty,
age. NavigationSnapshot projects them from either producer, with no
internal representation: uncertainty is an ErrorEllipse, not a
covariance matrix.
Structs§
- Error
Ellipse - 1σ horizontal position error ellipse.
- Ground
Track - Course and speed over ground.
- Navigation
Snapshot - Vessel state at an instant, as far as the producer knows.
