Informations about Eckstein-Hechler orbit propagation analytical model - DEPRECATED
infos = CL_ex_eckHechInfos(mean_cir [,er,mu,j1jn])
This function is deprecated.
Replacement function: CL_ex_getInfo
Computes data related to Eckstein Hechler orbit propagation analytical model.
These data are:
- Eccentricity vector of frozen orbit
- Secular drifts of some angular orbital elements
The output is a structure with the following fields:
- infos.exf: Mean eccentricity vector x-component of frozen orbit
- infos.eyf: Mean eccentricity vector y-component of frozen orbit
- infos.dgomdt: Secular drift of mean right ascension of ascending node [rad/s]
- infos.dpsodt: Secular drift of mean argument of latitude [rad/s]
Note:
The outputs only depend on semi major-axis and inclination.
See CL_ex_eckHech for more details on the propagation model.
Warning :
- The input argument "zonals" is deprecated as of CelestLab v3.0.0. It has been replaced by "j1jn".
Mean orbital elements (6xN)
(optional) Equatorial radius [m] (default is %CL_eqRad)
(optional) Gravitational constant [m^3/s^2] (default value is %CL_mu)
(optional) Vector of zonal coefficients J1 to Jn (troncated to J6) to be used (default is %CL_j1jn(1:6)) (1xNz)
(structure) Data for the given orbital elements (containing (1xN) vectors)
