class latom.analyzer.analyzer.Analyzer(body, sc)

Bases: object

Analyzer class defines the methods to analyze the results of a simulation.

Parameters

• body (Primary) – Instance of Primary class describing the central attracting body

• sc (Spacecraft) – Instance of Spacecraft class describing the spacecraft characteristics

Variables

• body (Primary) – Instance of Primary class describing the central attracting body

• sc (Spacecraft) – Instance of Spacecraft class describing the spacecraft characteristics

• phase_name (str) – Describes the phase name in case of multi-phase trajectories

• nlp (NLP) – Instance of NLP object describing the type of Non Linear Problem solver used

• tof (float) – Value of the time of flight resulting by the simulation [s]

• tof_exp (float) – Value of the time of flight of the explicit simulation [s]

• err (float) – Value of the error between the optimized simulation results and the explicit simulation results

• rm_res (float) – Value of the central body radius [- or m]

run_driver()

Runs the optimization.

Returns

failed – Returns the result of the optimization 0 or 1

Return type

int

get_time_series(p, scaled=False)

Access the time series of the simulation.

Parameters

• p (Problem) – Instance of Problem class

• scaled (bool) – Scales the simulation results

get_solution_dictionary(p, scaled=False)

Parameters

• p (Problem) – Instance of Problem class

• scaled (bool) – Scales the simulation results

Returns

sol – Dictionary containing the NLP solution

Return type

dict

get_solutions(explicit=True, scaled=False)

Access the simulation solution.

Parameters

• explicit (bool) – Computes also the explicit simulation. Default is True

• scaled (bool) – Scales the simulation results. Default is False

save(rec_file)

Pickle the whole Analyzer class.

Parameters

rec_file (str) – Directory path to the file where the Analyzer is serialized
