Lyddane orbit propagation analytical model (mean elements)
[mean_kep] = CL_ex_meanLyddane(osc_kep [,er,mu,zonals])
Computes the mean Keplerian elements mean_kep from the osculating Keplerian elements osc_kep.
The orbital elements are the following:
Warnings :
- This function does not work for inclinations close to the critical inclinations (63.43494882 deg and 116.5650512 deg)
- This function does not work for eccentricities higher than 0.9
Osculating Keplerian elements [sma;ecc;inc;pom;raan;anm] (6xN)
(optional) Equatorial radius [m] (default is %CL_eqRad)
(optional) Gravitational constant [m^3/s^2] (default value is %CL_mu)
(optional) Vector of zonals coefficients J1 to Jn (troncated to J5) to be used (default is %CL_j1jn(1:5)) (Nz x 1)
