Bases: Model

TargetScan trajectory model.

This model represents a trajectory that scans between two target locations on a celestial body.

Construct a TargetScan object.

Parameters:

start_lla (LLA) -- The starting location.
end_lla (LLA) -- The ending location.
start_instant (Instant) -- The starting instant.
end_instant (Instant) -- The ending instant.
celestial (Celestial) -- The celestial body. Defaults to Earth.WGS84().
step_size (Duration) -- The step size for the trajectory. Defaults to 1e-2 seconds.

Returns:

The TargetScan object.

Return type:

TargetScan

Methods

`calculate_state_at`	Calculate the state at a given instant.
`calculate_states_at`	Calculate the states at given instants.
`from_ground_speed`	Construct a TargetScan object from ground speed.
`get_celestial`	Get the celestial object of the target scan.
`get_end_instant`	Get the ending instant of the target scan.
`get_end_lla`	Get the ending LLA of the target scan.
`get_start_instant`	Get the starting instant of the target scan.
`get_start_lla`	Get the starting LLA of the target scan.
`get_step_size`	Get the step size of the target scan.
`is_defined`	Check if the model is defined.

calculate_state_at( self: ostk.astrodynamics.trajectory.model.TargetScan, instant: ostk.physics.time.Instant, ) → ostk.astrodynamics.trajectory.State¶

Calculate the state at a given instant.

Parameters:: instant (Instant) -- The instant.
Returns:: The state at the given instant.
Return type:: State

calculate_states_at( self: ostk.astrodynamics.trajectory.Model, instants: list[ostk.physics.time.Instant], ) → list[ostk.astrodynamics.trajectory.State]¶

Calculate the states at given instants. It can be more performant than looping calculate_state_at for multiple instants.

@param instants The instants.

Returns:: The states at the given instants.
Return type:: Array<State>
