ostk.astrodynamics.Trajectory

class Trajectory(*args, **kwargs)

Bases: pybind11_object

Path followed by an object through space as a function of time.

Overloaded function.

1. __init__(self: ostk.astrodynamics.Trajectory, model: ostk::astrodynamics::trajectory::Model) -> None

   Construct a Trajectory object from a model.

   Args:

   model (trajectory.Model): The model of the trajectory.

   Returns:

   Trajectory: The Trajectory object.

2. __init__(self: ostk.astrodynamics.Trajectory, states: list[ostk::astrodynamics::trajectory::State]) -> None

   Construct a Trajectory object from an array of states.

   Args:

   states (list[State]): The states of the trajectory.

   Returns:

   Trajectory: The Trajectory object.

Methods

access_model	Access the model of the trajectory.
get_state_at	Get the state of the trajectory at a given instant.
get_states_at	Get the states of the trajectory at a given set of instants.
is_defined	Check if the trajectory is defined.
position	Create a Trajectory object representing a position.
undefined	Create an undefined Trajectory object.

access_model(

self: ostk.astrodynamics.Trajectory,

) → ostk::astrodynamics::trajectory::Model

Access the model of the trajectory.

Returns:

The model of the trajectory.

Return type:

Model

get_state_at(

self: ostk.astrodynamics.Trajectory,

instant: ostk.physics.time.Instant,

) → ostk::astrodynamics::trajectory::State

Get the state of the trajectory at a given instant.

Parameters:

instant (Instant) -- The instant.

Returns:

The state of the trajectory at the given instant.

Return type:

State

get_states_at(

self: ostk.astrodynamics.Trajectory,

instants: list[ostk.physics.time.Instant],

) → list[ostk::astrodynamics::trajectory::State]

Get the states of the trajectory at a given set of instants. It can be more performant than looping calculate_state_at for multiple instants.

Parameters:

instants (list[Instant]) -- The instants.

Returns:

The states of the trajectory at the given instants.

Return type:

list[State]

is_defined(self: ostk.astrodynamics.Trajectory) → bool

Check if the trajectory is defined.

Returns:

True if the trajectory is defined, False otherwise.

Return type:

bool

static position(

position: ostk.physics.coordinate.Position,

) → ostk.astrodynamics.Trajectory

Create a Trajectory object representing a position.

Parameters:

position (Position) -- The position. Must be in the ITRF frame.

Returns:

The Trajectory object representing the position.

Return type:

Trajectory

static undefined() → ostk.astrodynamics.Trajectory

Create an undefined Trajectory object.

Returns:

The undefined Trajectory object.

Return type:

Trajectory
