Data Storage and Transmission
Up to 700 Mbits of data (scientific, attitude, and housekeeping
data from both the XRT and WFC) can be stored on the two on
board tape recorders,
and transmitted to the ground during ground station contacts.
All necessary telecommands
for S/C operations for one day must
be loaded during the five or six consecutive GSOC contact orbits.
At any given time, at most 
pointing positions can be stored
by the system. Thus a large number of very short duration observations
cannot be performed.
