What To Know About Satellite Footprint Maps

If you happen to be a consumer looking to get a satellite dish, or a communications network or provider setting up a system, then satellite footprint maps may be of much interest to you.  It is this sort of map which determines the area of coverage for a system, as well as the actual diameter of a satellite dish, which is necessary to figure out what is needed to receive a transponder signal.  A satellite footprint measures the coverage of a transponder’s ground area.  There actually are often varying maps, one for each different transponder.  Such maps will provide a measurement of area signal strength or an estimate of the required minimal dish diameter for the given area.

When defining the coverage area on a satellite footprint map, it is a key thing to know that coverage maps generally indicate areas of service and reception for radio stations which transmit signals.  Such maps can be useful not only for radio purposes, but for cell phone tower coverage, for satellite companies, and for television stations.  It is for satellite purposes that the maps are referred to as footprints.  Whenever proper equipment is performing under generally expected conditions, coverage maps can tell you the area in which people should be receiving good reception of the satellite signal.  Also, you can tell alternative places where you can get stronger reception or at least usable production out of the service.

Among the limitations for these maps is the fact that there can be parts of the reception area that are poorer in reception quality.  With these maps, no one should take the boundary lines on the coverage area to mean that the coverage is flat limited to that area, because these maps merely present a general coverage area, particularly in the case of large regions.  For example, just because a particular map ends roughly at the border of, say, California doesn’t mean you might not get sparse coverage in Arizona or something.  Despite the fact that broadcasters and carriers make it a goal to avoid dead zones in their networks, it is very difficult to accomplish – therefore you’ll likely see cracks in coverage at some points within a coverage network.

There is a vast array of satellite footprint maps available, as there are a tremendous number of footprints in existence.  Some of these mapping areas include (in Australia) the Western Satellite footprint – which involves areas such as Perth and Sydney; the Telestat network involving Canada; and various areas in the United States and Canada, covering places like Florida and Alaska.

There are obvious advantages to having knowledge of satellite footprint maps.  For instance, the very thought that signals could spill over into areas you thought might not be previously covered by the particular footprint.  This sort of thing is especially helpful to those who have issues with coverage in their own area by a provider.  In some cases, it may be possible to be located in an area where a signal spills over to your location.  Be advised, of course, that it’s always wise to check the legality of anything you might take interest in – you don’t want to be watching Cops and have them actually busting your door down, after all.
