Examples

# initial setup
import scarabaeus as scb

get_state(epoch_0, reference_frame: str = 'J2000', origin: str = 'EARTH')#

Retrieves the state of the body relative to a given origin in a specified reference frame.

Parameters:

epoch_0 (EpochArray) – The epoch times for which the state is to be computed.
reference_frame (str) – The reference frame in which the state is desired. Defaults to ‘J2000’.
origin (str) – The origin body relative to which the state is computed. Defaults to 'EARTH'.

Returns:

state_vector – The state vector of the body relative to the origin.

Return type:
