Orbit properties depending on J2 (mean motion, period, nodal period, ...)
[par] = CL_op_paramsJ2(type_output,sma,ecc,inc [,er,mu,j2,rotr_pla]) [par1,par2] = CL_op_paramsJ2([type_output1,type_output2],sma,ecc,inc [,er,mu,j2,rotr_pla]) [par1,par2,par3] = CL_op_paramsJ2([type_output1,type_output2 type_output3],sma,ecc,inc [,er,mu,j2,rotr_pla])
Computes quantities related to the mean motion taking the effect of J2 into account.
type_output can be :
- 'mm' : mean motion
- 'per' : period (from periapsis to the next one)
- 'nodper' : nodal period (from ascending node to the next one)
- 'lgap' : gap in longitude between 2 consecutive ground tracks
Name(s) of the quantities to be computed. Possible names are: 'mm','per','nodper','lgap' (1 x Noutput)
semi major axis [m] (1xN)
eccentricity (1xN)
inclination [rad] (1xN)
(optional) equatorial radius [m] (default is %CL_eqRad)
(optional) Gravitational constant [m^3/s^2] (default value is %CL_mu)
(optional) zonal coefficient (second zonal harmonic) (default is %CL_j1jn(2))
(optional) rotation rate of the planet [rad/s] (default is %CL_rotrBody)
mean motion, period, nodal period or longitude gap between 2 ground tracks [rad/s,s,s,rad] (1xN)
