Using elevation and azimuth data (which are in degrees), how to plot the location of the satellite marked with a cross? The human in the middle of the plot marks the receiver.

Just use built-in function sph2cart
[X,Y,Z] = sph2cart(az,el,r);
plot3(0,0,0,'^r') % human
hold on
plot3(X,Y,Z,'xb') % blue cross
hold off

Some examples
t = linspace(0,2*pi,40);
r = linspace(0,1,10);
[T,R] = meshgrid(t,r);
[X,Y] = pol2cart(T,R);
h = surf(X,Y,X*0); % flat surface
hold on
set(h,'FaceColor','g')
set(h,'EdgeColor',[1 1 1]/2)
p = linspace(0,pi/2,20);
[T,P] = meshgrid(t,p);
[X,Y,Z] = sph2cart(T,P,1);
h = surf(X,Y,Z); % half of a sphere
set(h,'FaceColor','none')
set(h,'EdgeColor',[1 1 1]/1.2)
text(1.2,0,'N') % north?
text(0,-1.2,'E') % easth?
hold off
axis equal
xlim([-1 1]*1.5)
ylim([-1 1]*1.5)
You can draw arc using plot3()
