Constructors
| ShipRelativePosition(AisTarget, AisTarget, Length, Angle, AisSafetyState, DateTimeOffset) |
Relative position instance |
Properties
| Bearing |
The bearing between the sips (Compass direction from From to To) |
| CalculationTime |
The time this record was calculated. |
| ClosestPointOfApproach |
Distance at closest point of approach |
| Distance |
The current distance between the ships |
| From |
Ship from which this relative position is seen (typically the own ship, but of course it's also possible to calculate possible collision vectors between arbitrary ships) |
| RelativeDirection |
Direction in which the other ship is seen from From when looking to the bow. A negative value means the other ship is on the port bow, a positive value on the starboard bow. Only available if the source ship has a valid heading. |
| SafetyState |
Safety state |
| TimeOfClosestPointOfApproach |
Time at which the closest point will be reached |
| To |
Ship to which this relative position is calculated |
Methods
| TimeToClosestPointOfApproach(DateTimeOffset) |
Calculate the time of closes approach with a given "now" |
