Shuttle Frequencies
The Space Shuttle transmits on three frequency bands: UHF, S-Band, and Ku-
Band. The UHF frequencies are simple AM voice and are very easy to copy. These
frequencies are used for launch and landing operations, EVA operations, and as
an additional voice downlink when other channels are in use for the current
ground station has no S-Band capability.
The frequencies in use are:
296.800 Mhz: Air-to-ground, or Orbiter to suit
259.700 Mhz: Air-to-ground, or suit to Orbiter
279.000 Mhz: Suit-to-Orbiter, or suit-to-suit
243.000 MHz: Standard military aircraft emergency frequency
The S-Band system is one of the primary Orbiter downlink bands. The voice
channels are digital slope delta modulated and are multiplexed in with the
rest of the Orbiter telemetry and is very difficult to copy. Much of the
downlink TV is on S-Band also, but is wideband FM and should be easy to copy.
The frequencies are:
2287.500 Mhz:
Primary digital downlink
2250.000 Mhz:
Wideband FM with either main engine analog telemetry during launch, or TV
during orbit operations.
The Ku-Band system is used in conjunction with the tracking and data relay
satellites and is used much more heavily in Spacelab flights than in others.
The data rate is very high (50 Mbit/s). These transmissions are directed to
TDRS satellites in geostationary orbit on a frequency of 15.003 GHz.
