CL_op_equatorialSwath

Intersection of swath with equator (circular orbit and field of view)

Calling Sequence

ang2 = CL_op_equatorialSwath(cmd, sma, inc, ang1 [[, er, mu, j2, rotr_pla]])

Description

Parameters

cmd :

(string) Action required: "cen2dlon" or "dlon2cen"

sma :

Semi major axis [m] (1xN or 1x1)

inc :

Inclination [rad] (1xN or 1x1)

ang1 :

Input angle: center angle or half longitude span [rad] (1xN or 1x1)

er :

(optional) Equatorial radius [m] (default is %CL_eqRad)

mu :

(optional) Gravitational constant [m^3/s^2] (default value is %CL_mu)

j2 :

(optional) Second zonal harmonic (default is %CL_j1jn(2))

rotr_pla:

(optional) Body rotation rate. Default: %CL_rotrBody. [rad/s] (1x1)
