B=earth_station_longitude-s_s_latitude

s_s_latitude is not defined

b=acosd(cosd(Earth_station_latitude)*cosd(B))

Earth_station_latitude with a capital E is not defined. Variable names are case sensitive.

Hello!

I understand that you are facing issues while running the code, where the user is prompted to enter latitude and longitude values and calculate the angles based on the input arguments.

I have tried to execute the code and found that there are some lexical/syntactical errors in the code, like “s_s_latitude” is undefined and variables name are case sensitive.

Please find the excutable code below:

clc 
clear all 
close all 
earth_station_longitude=input('prompt'); 
earth_station_latitude=input('prompt'); 
sub_satellite_latitude=input('get longitude'); 
B=earth_station_longitude-sub_satellite_latitude 
b=acosd(cosd(earth_station_latitude)*cosd(B)) 
a=42164 
R=6371 
range=sqrt(R^2+a^2-2*R*a*cosd(b)) 
elevation_angle=acosd((a*sind(b))/range) 
A=asind(sind(abs(B))/sind(b)) 
if(earth_station_latitude<0)&&(B<0) 
    AZ=A 
elseif(earth_station_latitude>0)&&(B<0) 
    AZ=180-A 
elseif(earth_station_latitude>0)&&(B>0) 
    AZ=180+A 
else 
    AZ=360-A 
end
