[QUOTE="hvdh, post: 1005396, member: 187415"] Well popovp, as [USER=408043]@Orbitalzone_Delta[/USER] and [USER=404726]@MCelliotG[/USER] pointed out, there is something wrong at Satbeams with the beam numbering. Or at least, it's different... hence all the confusion. Surely that will be fixed in due time. Meanwhile, on my search for these beams, I found a list at fcc.gov with lots of infos about IS-33e: [URL='http://licensing.fcc.gov/cgi-bin/ws.exe/prod/ib/forms/attachment_menu.hts?id_app_num=105895&acct=783256&id_form_num=12&filing_key=-272376']Notify going to PDF Form[/URL] See the Engineering Statement, page 12, that lists all beams and the coordinates that the beams are pointed to (bore-sight). I was wondering what all these GXT files were about. GXT files seem to be a special format for projecting gain contours onto a map. A program (freeware, I think) for reading GXT files called GIMS is available at ITU: [URL='http://www.itu.int/en/ITU-R/software/Pages/gims.aspx']PAGE TITLE GOES HERE[/URL] In this software, a selected GXT beam shape can be "squinted" to any direction on earth. I tried to get spot beam # 34 as [USER=404726]@MCelliotG[/USER] posted above, it looks quite similar! Contours: -2, -4, -6, -8, -10, -15 and -20 dB [ATTACH]103731[/ATTACH] [/QUOTE]
