Compute the angular velocities harmonic guidance profile. The spin components are decomposed into Fourier Series and the rotation is computed from the resulting series using the specified integration method and integStep.

The Fourier coefficients are computed between t_ref - T/2 and t_ref + T/2.

Parameters:

attitude - attitude provider

provider - pv coordinates provider (can be a propagator)

frame - frame in which the guidance profile is to be expressed

tref - reference date, usually date of reference raan

period - period of the spin vector components

order - order of development of the components of the spin vector

integType - integration type (Wilcox or Edwards)

integStep - integration step

Returns:

the generated guidance profile

Throws:

OrekitException - if guidance pofile cannot be computed
