Public Functions

Trajectory(const Model &aModel)¶

Constructor (model)

Tabulated model = Tabulated::Load(File::Path(Path::Parse("/path/to/trajectory.csv")));
Trajectory trajectory = { model };

Parameters:: aModel -- A trajectory model

Trajectory(const Array<State> &aStateArray)¶

Constructor (state array)

Array<State> stateArray = { ... };
Trajectory trajectory = { stateArray };

Parameters:: aStateArray -- An array of states

Trajectory(const Trajectory &aTrajectory)¶

Copy constructor.

Parameters:: aTrajectory -- A trajectory

Trajectory &operator=(const Trajectory &aTrajectory)¶: Copy assignment operator.

bool operator==(const Trajectory &aTrajectory) const¶

Equal to operator.

Trajectory(...) == Trajectory(...);

Parameters:: aTrajectory -- A trajectory
Returns:: True if trajectories are equal

bool operator!=(const Trajectory &aTrajectory) const¶

Not equal to operator.

Trajectory(...) != Trajectory(...);

Parameters:: aTrajectory -- A trajectory
Returns:: True if trajectories are not equal

bool isDefined() const¶

Check if trajectory is defined.

Trajectory(...).isDefined();

Returns:: True if trajectory is defined

const Model &accessModel() const¶

Access trajectory model.

Returns:: Reference to trajectory model

State getStateAt(const Instant &anInstant) const¶

Get state at a given instant.

Trajectory trajectory = { ... };
Instant instant = { ... };
State state = trajectory.getStateAt(instant);

Parameters:: anInstant -- An instant
Returns:: State

Array<State> getStatesAt(const Array<Instant> &anInstantArray) const¶

Get states at a given instants.

Trajectory trajectory = { ... };
Array<Instant> instants = { ... };
Array<State> state = trajectory.getStatesAt(instants);

Parameters:: anInstantArray -- An array of instants
Returns:: Array of states

virtual void print(std::ostream &anOutputStream, bool displayDecorator = true) const¶

Print trajectory to output stream.

Trajectory trajectory = { ... };
trajectory.print(std::cout, true);

Parameters:

anOutputStream -- An output stream
displayDecorator -- If true, display decorator

Public Static Functions

static Trajectory Undefined()¶

Constructs an undefined trajectory.

Trajectory trajectory = Trajectory::Undefined(); // Undefined

Returns:: Undefined trajectory

static Trajectory Position(const physics::coordinate::Position &aPosition)¶

Constructs a trajectory from a given position.

Position position = Position::Meters({ 0.0, 0.0, 0.0 }, Frame::GCRF());
Trajectory trajectory = Trajectory::Position(position);

Parameters:: aPosition -- A position
Returns:: Static trajectory

Friends

friend std::ostream &operator<<(std::ostream &anOutputStream, const Trajectory &aTrajectory)¶

Output stream operator.

std::cout << Trajectory(...);

Parameters:

anOutputStream -- An output stream
aTrajectory -- A trajectory

Returns:

A reference to output stream
