Struct TargetObservation 

pub struct TargetObservation { /* private fields */ }

One sighting of a target: radar bearing and range, AIS position report, or any other position source.

Position is the common denominator from which tracks are built. Sources that also report course and speed over ground (AIS) add them; the track prefers them to values fitted from positions.

Implementations

impl TargetObservation

pub const fn new(target: TargetId, position: Position, at: Instant<Utc>) -> Self

Target at a position at an instant.

pub fn from_contact( target: TargetId, own: Position, contact: Contact, at: Instant<Utc>, ) -> Result<Self>

Radar plot: true bearing and range from own position at the time of the plot.

Errors

As rhumb_destination: a plot beyond a pole.

pub const fn with_ground_track(self, ground_track: GroundTrack) -> Self

Adds the target’s reported course and speed over ground.

pub const fn with_heading(self, heading: TrueCourse) -> Self

Adds the target’s reported heading.

pub const fn target(&self) -> TargetId

Target.

pub const fn position(&self) -> Position

Position.

pub const fn at(&self) -> Instant<Utc>

Time.

pub const fn ground_track(&self) -> Option<GroundTrack>

Reported course and speed, if any.

pub const fn heading(&self) -> Option<TrueCourse>

Reported heading, if any.
