This block allows for calculation of the solar drag force acting upon the illuminated sacecraft.
This block calculates the solar drag force acting on the spacecraft using simple drag model. Block can accept herited events.
Input 1: Postion vector of the illuminated spacecraft (inertial reference frame) [m]. (3x1)
Input 2: Postion vector of the Sun (inertial reference frame) [m]. (3x1)
Input 3: Reflectivity coefficient (property of the spacecrafts surface) described by 1x1 vector (Only Cp, does not include mass or surface area)
Input 4: Surface area (cross-section facing the sun) [m^2]. (1x1)
Output 1: Drag force vector (in the same reference frame as the position vectors) [N]. (3x1)
Accept herited events (0/1) - If 1 the block will accept herited events, if 0 it will have its own event input.
Accept herited events (0/1)= 0
