You must select the satellite first and then click on the map. If you change satellite, click the map again nearby the original point till the satellite pointing angles calculate again.
Choose the satellite you want to point at using the pull down menu box at the lower left under the map. Put your mouse cursor near your location and then double click the left hand button, or hold down and drag the map.
The map image will move so that the chosen point is in the centre. The latitude and longitude of the dot at the centre of the map is then displayed below the map, together with your satellite dish pointing angles: azimuth, elevation and polarisation. To get close to your site, click on the plus sign + in the array of navigation boxes at the top left side of the map. The map scale will change so that you can home in accurately on your location. Repeat. Choose the Map, Satellite or Hybrid version to see roads, small town names and photo images of the ground. Not everywhere is yet available at the highest resolution.
Satellite dish pointing (Azimuth and elevation i.e. up/down and sideways adjustment mount): Set the dish elevation (up/down) angle first. There may be a scale on the bracket at the back. An inclinometer may be of use if you know the dish elevation offset angle. Set the feed rotation polarisation angle also. There may be polarisation rotation scale on the LNBF feed horn throat. Facing the satellite, clockwise polarisation is positive, negative is anticlockwise. For the azimuth angle (sideways) use a magnetic compass and swing the dish boldly sideways to find the satellite on the first swing. Then spend half an hour peaking up. Peaking up is really important for long term service quality and minimum outage time during rain fades.
Dish pointing (Polar mount):
Only your latitude matters. Set the main motor axis angle and the small downward tilt of the dish and with the motor central align the dish towards the due south satellite. Motor rotation angles to the east are positive, to the west negative.
The Afghanistan map above comes with the following cities and towns marked: Herat, Meymaneh, Kandahar, Mazar-e Sharif and Kabul. Expressions like "helmund province" will work in the geocoder box. As you expand the scale to look more closely, you will need to identify your town and roads yourself from local knowledge. The starting satellite position shown is Eutelsat AM22 at 53 east. Choose your required satellite.
Safety Warning: The dish pointing angle results of this page may be wrong. The latitude and longitude and accuracy are not intended for military purposes, or the navigation of aircraft, ship or other vehicle purposes. Magnetic azimuth bearings are approximate and based on my earth's magnetic field model. Use is therefore entirely at your own risk. Use your common sense. Take care with satellite dish pointing to not injure others by dropping tools or hurting yourself by falling down.
