Orbit properties depending on J2 (mean motion, period, nodal period, ...)
[par1, par2, ...] = CL_op_paramsJ2(type_output, 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". (1xNoutput)
Semi-major axis. [m] (1xN)
Eccentricity. (1xN)
Inclination. [rad] (1xN)
(optional) Equatorial radius. Default: %CL_eqRad. [m] (1x1)
(optional) Gravitational constant. Default: %CL_mu. [m^3/s^2] (1x1)
(optional) Second zonal harmonic (unnormalized). Default: %CL_j1jn(2). [-] (1x1)
(optional) Body rotation rate. Default: %CL_rotrBody. [rad/s] (1x1)
Mean motion, period, nodal period or longitude gap between 2 ground tracks. [rad/s, s, s, rad] (1xN)
