Imagine you are out in space, looking down on the Earth.     There are many clusters of satellites in "geostationary orbit". Each cluster contains satellites which are so close to each other (usually less than 100 km apart) that their signals appear to arrive on earth from a single point in space. This point is usually specified by its angular position relative to the prime meridian which passes through Greenwich, UK. The yellow blobs represent three of the satellite clusters which transmit TV programmes back down to earth. The Hot Bird satellites are 13 degrees east of the Prime Meridian, Astra-1 satellites at 19.2 degrees and Astra-2 satellites at 28.2 degrees (plus Eurobird at 28.5) for Sky Digital and other English language programmes. They are 22300 miles above the African equator. See map below. The numbers refer to the angles measured from the centre of the Earth between a line passing through 0 degrees on the Prime Meridian (off the African coast) and another line from the centre of the Earth and passing through each satellite. Here are the satellites sitting 22300 miles above the equator (on the latitude line of 0 degrees). The azimuth angle is NOT the compass angle, although, as the UK is very close to the Prime Meridian longitude line of 0 degrees, the compass angle is often a reasonable approximation if you are in the UK. Elsewhere it's not true, as you can see from the map. Look at Vatican City in Italy. Hot Bird (at 13 degrees) is actually directly south of the Vatican so pointing your dish 13 degrees east of south on your compass will miss the satellite by thousands of miles! Read about longitude and latitude here: http://www.nationalatlas.gov/articles/mapping/a_latlong.html and http://www.socialstudiesforkids.com/articles/geography/equatorprimemeridian.htm What is Elevation? The elevation angle of a satellite is the angle measured between the horizon as you see it and a line drawn between you and the satellite. Because the Earth is round, the angles in the UK are typically 20 to 26 degrees. In Europe 26 to 36 degrees and, of course, if you are standing on the Equator in Africa, the satellites are almost directly above you at 90 degrees. Use an az/el calculator to determine the satellite location relative to your lat/long position. You can get your lat/longitude by typing in your postcode here: http://www.multimap.com Use it in this elevation calculator for Astra 2A Now go to the next page ©2004-2011 SatCure  Send this page address - CLICK HERE - to a friend !
