compute_ric_basis_vectors(p_ric, v_ric)

Compute the orientation of an RIC coordinate frame relative to the input coordinate frame.

Parameters:
p_ric, v_ricarray_like

Position and velocity in an input coordinate frame

Returns:
u_r, u_i, u_c(3,) ndarray

Radial, in-track, and cross-track unit vectors that specify the RIC frame
