  1. What is GOES DCS Current Use and Capacity?

  2. Outline Basic GOES DCS System Definitions Number of Users and Assigned DCP PDTs Communications Use Channel Division ST on East and West (300/1200) RR on East and West (Data Rate) CS1 and CS2 Special Channels Usage By Occupancy (By Channel Seconds ) Assigned Actual Possible

  3. Raw Usage: # Messages Processed Day 120 2014: All Messages 742,106 day / 30,917 hour (May 2009 469,000 per day) Messages Labeled G: 712,539 day / 29,689 hour Error Messages all types: 29,477 day / 1228 hour

  4. User Assignments Total # PDTs: 38,284 # Active: 25,269 # Unactive: 6,107 # Deactivated: 6,052 # Blank: 855 # Users May 2014 : 788 (May 2009: 552)

  5. Channel Assignments Total # Assigned: 239 # ST 300 / Auto: 169 # RR 300 / Auto: 20 # Test: 6 # Pilot: 2 # ST / I 1200: 20 # CS2 1200: 1 # Dedicated: 4 # 100 International: 14

  6. DCP Assignments by TX Interval and BAUD GOES R Imagery Intervals: 5 Min and 1 Min

  7. Assignments by User

  8. Assignments by User 2 CANADA USERS Break Down

  9. GOES DCS Message Length by Channel Type and % Channel Occupancy May 2009 and 2014

  10. Possible Capacity Channel Seconds Assumptions: All channels are 300 BPS 239 assigned / defined channels > 200 CS1 AND > 200 CS2 For Each Hour Capacity in Channel Seconds: 1,440,000 ST Msgs per hour at 10 seconds: 144,000 ST Msgs per hour at 5 seconds: 288,000 ST Msgs per hour at 2 seconds: 720,000

  11. Current Assigned Capacity Channel Seconds Assigned Capacity By Active and Unactive: 31,366 X 10> 313,660 Channel Seconds/Hour. 10 seconds per hour assumed to be assigned per DCP 22% of Capacity committed by assignment for a full 10 second window By Actual Message traffic at 4 seconds per message > 29689 X 4=118,756 Channel Seconds 8% of Capacity by actual use
