UHF Satellite Frequency Plan


The Downlink frequency is in the 240 to 270 MHz range with the associated uplink at +33.6, 41, 73.1, 53.6 or 41 MHz above the down link.
Sometimes the uplink is in the 7.9 to 8.4 GHz band.  This places the uplinks somewhere in the 292 to 317 MHz range.

Note that the 225 to 400 MHz frequency range is for military use, not just for satellites.
 

The actual Satellite DL frequencies rounded to the nearest whole MHz are:

UHF Follow On

MIL-STD-188-181 may be a recerence document.
There are 10 Geostationary Satellites located at:
F1 - 40 W, Altantic Rim, ustable and not used
F2 = 65 E,  Europe, Russia, China, some of Austraila
F3 = 15 W,  Eastern US
F4 = 157 W,  all of U.S.
F5 = 73 E, Eorope, Russia, China, all of Austraila
F6 = 107 W, all of U.S.
F7 = 100 W, all of U.S.
F8 = 175E, Pacific Rim
F9 = 145 W, Western side of Pacific Rim
F10 = Europe

Fleet Satellite Communications (FLTSATCOM)

FM 24-11 is a reference document.
There are 5 Geostationary Satellites located at:
FLTSATCOM 1  = 52 E, Europe
FLTSATCOM 4 = 170 E, Pacific Rim
FLTSATCOM 5 = 95 W, Americas
FLTSATCOM 7 = 114W, Americas (centered on the US)
FLTSATCOM 8 = 25 W, Atlantic Rim
 

Defense Satellite Communications System (DSCS) (Say "Disk-us")

I worked for TRW Microwave in Sunnyvale, CA and we made components for TRW Rendondo Beach, CA who built the birds.

The 290 to 310 band has some intercepts from the MILCOM mailing list that may be sats rather than aircraft.
Maybe the aircraft band is 311 to 389?
