I'm creating a program that models the flight path of a satellite in low earth orbit, where the changing densities is necessary to compute the drag forces. My function for calculating the drag forces is as follows:
function function [ax,ay] = LEO_drag_acceleration(x,y,vx,vy,g)
C_d = 2.2; h = y; A = .3; vel = sqrt(vx.^2 + vy.^2); rho = LEO_density_range(h); ax = -((rho*C_d*A)/2)*vel*vx; ay = -g-((rho*C_d*A)/2)*vel*vy; return end
and the LEO_density_range function is as follows: function rho = LEO_density_range(h) if h < 25000 rho = 1.225; elseif h >= 25000 && h < 30000; rho = 3.899*10^-2; elseif h >= 30000 && h < 40000; rho = 1.744*10^-2; elseif h >= 40000 && h < 50000; rho = 3.972*10^-3; elseif h >= 50000 && h < 60000; rho = 1.057*10^-3; elseif h >= 60000 && h < 70000; rho = 3.206*10^-4; elseif h >= 70000 && h < 80000; rho = 8.770*10^-5; elseif h >= 80000 && h < 90000; rho = 1.905*10^-5; elseif h >= 90000 && h < 100000; rho = 3.396*10^-6; elseif h >= 100000 && h < 110000; rho = 5.297*10^-7; elseif h >= 110000 && h < 120000; rho = 9.661*10^-8; elseif h >= 120000 && h < 130000; rho = 2.438*10^-8; elseif h >= 130000 && h < 140000; rho = 8.484*10^-9; elseif h >= 140000 && h < 150000; rho = 3.845*10^-9; elseif h >= 150000 && h < 180000; rho = 2.070*10^-9; elseif h >= 180000 && h < 200000; rho = 5.465*10^-10; elseif h >= 200000 && h < 250000; rho = 2.789*10^-10; elseif h >= 250000 && h < 300000; rho = 7.248*10^-11; return end
Any ideas on how to solve this issue?
