CL_cw_diffDrag

Description

• This function is deprecated.

• Computes the differential acceleration of a chaser relative to a target due to atmospheric drag.

  The atmospheric density model used is an exponential model.

Parameters

altitude:

Target altitude [m] (1xN)

ballistic_coef_target:

Target ballistic coefficient S*cx/m S=equivalent drag surface, cx = drag coefficient, m = mass [m^2/kg] (1xN)

ballistic_coef_chaser:

Chaser ballistic coefficient S*cx/m S=equivalent drag surface, cx = drag coefficient, m = mass [m^2/kg] (1xN)

er:

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

mu:

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

acc_diff:

Differential acceleration (chaser relative to target) [m/s^2] (1xN)
