[Sis-csi] High-rate uplinks

[Ernst, Darrell E.]

That is generally correct in  most space systems.  The DOD uses SGLS
(Space Ground Link System).  The SGLS uplink channels are on the order
of 1 MHz wide.  They are in the S-band (1755-1850 MHz).  It has been
awhile, but I seem to recall there were a standard low and high data
rate.  The low was 9.6 Kbps.  The high might have been 1 Mbps, but I
could be wrong.  Should be able to find the SGLS info on the Web or
have someone at Aerospace send you the Aerospace SGLS manual.

I checked with my DoD contract.  He has only heard requirements for
low-rate uplinks.   Nothing in the order of 10 Mbps.  Note, however,
the
applications this groups is involved in is generally space-based
sensors.  So commands go up and large volumes come down.
