    DESCRIPTION       "Tracking Data Relay Satellite (TDRS) needs and coverage 
                       data is stored here.  This is for the currently unused 
                       operational concept where the TDRS Network Control
                       Center (NCC) would send the STScI TDRS availability 
                       information and there would be a negotiation for 
                       TDRS resources.  This has been occurring between PASS
                       and the NCC after SMSes have been generated.  

                       ICD-11 details the interface and mechanism for 
                       transferring this data.

                       PASSFile/Receive TDRS process the TDRS Needs Coverage
                       Reports from PASS and stores the data in this relation.
                       Orbifile/Update uses data in this relation to set
                       TDRS windows in the orbit file."
