CL_fo_albedoAcc

Description

• Acceleration due to constant albedo (reflected solar pressure).

• Notes:

  - The coordinates frame can be any frame.

  - The origin of the frame must be the central body, which is also the reflecting body.

  - The spacecraft is assumed spherical. Consequently, the acceleration vector lies in the plane formed by the central body, the perturbing body and the Sun.

  - The function uses pre-computed data present in the file "acc_albedo.dat" located in the CL_home()/data/force_models directory.

• See Force models for more details.

Parameters

pos:

Position vector [m]. (3xN or 3x1)

pos_sun:

Sun position vector (same frame as pos) [m]. (3xN or 3x1)

coefp:

SRP coefficient (cp*area/mass) [m^2/kg]. (1x1 or 1xN)

albedo:

(optional) Albedo coefficient. Default value is %CL_albedo. (1x1 or 1xN)

er:

(optional) Equatorial radius of reflecting body. Default is %CL_eqRad. [m] (1x1)

ersun:

(optional) Sun radius. Default is [] (internal value is used). [m] (1x1)

p0:

(optional) Solar radiation pressure at 1 AU. Default is [] (internal value is used). [N/m^2] (1x1)

acc:

Acceleration [m/s^2]. (3xN)

Examples

pos = [7000.e3; 0; 0]; // ECI pos_sun = CL_eph_sun(CL_dat_cal2cjd(2000,3,21)); // ECI coefp = 1.5 * 10 / 1000; CL_fo_albedoAcc(pos, pos_sun, coefp)
