 pointing calculator used to calculate the pointing angle of satellite by using local location
+
+by cloning or downloading the zip file you can see the app code in android studio by importing the project 
+
+the apk file of this project is available in the folder and zipped file from the 'pointingCalc-mukee' folder
+The application is calculate the azimuth and elevations angle of the satellite by using the site latitude and longitude and satellite longtude
+# Azimuth and Elevations calculator
+Azimuth angle means the angle between North, measured clockwise around the observer's horizon, and a celestial body (sun, moon). It can measured using a compass 
+
+Elevation angle is the vertical angle formed between the direction of travel of electromagnetic wave radiated from an earth station antenna pointing directly towards a satellite and horizontal plane.
+
+Inverted elevation is an elevation angle when the dish is inverted in upward direction.
+
+This app is developed by considering a Circular polarized antennas it may be left-hand (LHCP) or right-hand (RHCP). so the polarization angle is considered not important.
+
+Finally, if your satellite are in the west direction you can use the minus sign ex. if the satellite is at 18°W you can use '-18°' or 360-18=342.
