**             ****2.  Original TDRS H/I/J plan was to co-locate/activate a new generation TDRS in east and West; stored spare at 150 West.**
**            **** ****3.  TDRS-I (F9) launched 3/8/02, arrived 150 West 9/30/02.  On-orbit tests completed 2/14//03, NASA accepted 7/03/03.**
**             ****4.  Collocation at 174 West; F5/F8.  Synchronized drift patterns at 171.4/174.3 West. TDRS-8 (F8) to storage at 062 West after TDRS-6 (F6) arrival at 174 West; date TBD.**** **
**             ****5.  F8/F9/F10 add SMA (upgraded MA) and Ka-band (time shared with Ku-band SA-1 or SA-2) services. **
**             ****6.  KSA service remains restricted to RCP on F1, F3 KSA-1 and F4 per NASA.**
**             ****7.  No normal user support available via White Sands Alternate Resource Terminal (WART).**
**             ****8.  Dates are based on GMT when events occur near change of day.**
**             ****9.  F5, F6 and F7 polarization change during an active event requires WSC authorization and GCMR/command.**
**          **** ****10.  TDRS-J (F10) launched 12/5/02; arrived 150.764 West 12/16/02; on-orbit tests completed 5/09/03, NASA accepted 5/29/03; drift 150.7 to 040.9  West 7/08/04 to 11/17/04.**
**           ****11.  Reconfiguration: TDRS-I (F9) 150 to 171 West 12/15/03 to 1/17/04; TDRS-G (F7) 171 to 150 West 12/18/03 to 1/08/04; TDRS-E (F5) 174 to 173.6 West 4/6/04 to 4/29/04; to 171 West 9/03/04 to 9/09/04.**
**           ****12.  TDRS-I (F9) operational as TD-171 3/29/04.  Drift to 174.3 West completed 4/21/04; operational as TDW for KSA/SSA/SMA 4/23/04; leave 171 9/23/04 to storage 9/24/04 arrive 062.4 2/23/05.**
