CL_gm_orbit2inertialSph

Description

• Performs a conversion of spherical coordinates from an "orbit" reference frame to an inertial reference frame.

  The "orbit" reference frame is defined as follows:

  - X-axis: Towards the ascending node

  - Z-axis: Parallel to the angular momentum vector

  - Y-axis: Such that the frame is direct.

  

Parameters

inc:

Orbit's inclination [rad] (1xN)

raan:

Orbit's right ascension of ascending node [rad] (1xN)

alpha1:

Right ascension in orbit frame [rad] (1xN)

delta1:

Declination in orbit frame [rad] (1xN)

alpha2:

Right ascension in inertial frame [rad] (1xN)

delta2:

Declination in inertial frame [rad] (1xN)
