UPDATE: Feb 7, 2013 To Add KU45 @45W Footprints
UPDATE: Nov 23, 2013 To Change D5 Footprint from CONUS to Puerto Rico
This thread replaces the original Beam Footprints provided in August, 2009. The original Beam Footprint postings were provided as static JPG files. This new generation of Beam Footprints is presented as Google Earth media, allowing the viewer an unlimited ability to modify the data display. Thanks to Doug Brott for his help in providing a repository for the data.
Viewing this data requires the Google Earth application. The free application is available at
The Satellite Beam Footprint Library provided is the creation of dbstalk user spear61. His initiative and creativity have culminated with these Beam Footprint Maps.
The beam contour maps reflect the satellite operating at full power. Reception in this case is probably good out to the isobars in the low 50’s dBw. See Post #27 in this thread for more detail.
some comments from spear61 August, 2009
The FCC started publishing a web data base in the late summer of 2003. Any original license application filed before that date only has a "marker" in the file system and does not have any online data of any kind. If one of the "old" satellites is moved to a new location after mid 2003, the modification to the original license will include the new footprint data.
The Directv satellites that have zero beam data fall into the pre 2003 group of original licenses.
Quantity of beam footprints
- The Spaceway satellites are very unique and can essentially generate an infinite number of spots. DIRECTV applied and received an exemption allowing them to provide a couple of "examples" in digital form and sketches in their license that show how they can blanket the country with spots.
- Some of the other newer satellites generated so many beams that it overwhelmed the FCC filing system. Again, DIRECTV applied for and received an exemption to only show some examples in those cases.
- Beginning in 2009, a new database was implemented, allowing submission of more data. DIRECTV12 used that format; that is the reason we have a great deal of data for DIRECTV12. In the case of DIRECTV14, it appears the data for all proposed beams is available.
