tracking hubble

Hi. A group of us are building a sattelite tracking gizmo for a radio
amateur project and someone in the group. (Me) suggested it would arouse
interest if it we could use it to track hubble. We've got the downlink
frequency of hubble but we don't know what the doppler shift is or what
format theinformation downloaded from hubble would come in. Can anyone fill
in these gaps?

Thanks?

You can't receive from Hubble directly -- it does not transmit to Earth, but uses
the TDRSS satellites to relay its signals. If you want to listen in to Hubble's
data-stream, you'll have to get it from TDRSS.

Do you know any software thst trsckd them? We have used orbitron, satscape
and Ham radio deluxe, all of which track sattelites but it didn't see any
TDRSS sattelites in thier sat lists.

Thanks.

TDRSS are geostationary satellites; their locations can be found he

Thank you. Any idea how you get the info from hubble off them?
