nastro.types.GenericState

class nastro.types.GenericState(q1, q2, q3, q4, q5, q6, deg=False, wrap=False)

Bases: Generic

Base class for state vectors

Implements operations and basic functionality that is common to all types of state vectors and implements the containers that are used internally to manipulate their components. The elements q1 to q6 are representations of the six components of a state vector as numpy arrays.

This class is not meant to be instantiated directly, but to be subclassed to create specific types of state vectors: cartesian, keplerian, etc.

Attributes:

asarray

Time series of state vectors as a (6, N) numpy array

q1

q2

q3

q4

q5

q6

scalar

True for a single state vector

size

Number of state vectors in time series

Parameters:

• q1 (U) –

• q2 (U) –

• q3 (U) –

• q4 (U) –

• q5 (U) –

• q6 (U) –

• deg (bool) –

• wrap (bool) –

Methods

append(other)	Add state vector to time series
copy()	Return copy of state vector
from_tudat(state_history[, limits])	Generate state vector from Tudat state history
load(path[, relative])	Load state vector from npy file
save(path[, relative])	Save state vector to file
transform()	Transform state to a different reference frame

__init__(q1, q2, q3, q4, q5, q6, deg=False, wrap=False)

Parameters:

• q1 (U) –

• q2 (U) –

• q3 (U) –

• q4 (U) –

• q5 (U) –

• q6 (U) –

• deg (bool) –

• wrap (bool) –

Return type:

None
