ssapy_toolkit.Accelerations.accel_sun

Functions

accel_point_sun(r, time)

Point-mass solar gravity in GCRF, given raw_time (same input as leapfrog).
ssapy_toolkit.Accelerations.accel_sun.accel_point_sun(r: ndarray, time) → ndarray[source]

Point-mass solar gravity in GCRF, given raw_time (same input as leapfrog).

Parameters:

  • r (array_like, shape (3,)) – Satellite position vector in GCRF (m), Earth-centered.

  • time (float or datetime-like or array_like) – The time array element from leapfrog (same type you passed into leapfrog).

Returns:

a_sun – Acceleration from the Sun (m/s²).

Return type:

ndarray, shape (3,)
