WHAT IS DCS?

• Data Relay System Used for Transmission from
  Ground-Based Sensors through Satellite to
  Receiving Station.
• Carried on board NOAA Geostationary satellites
  since 1970s.

• Resource Management
• National, State, and Local Water Resource
  Managers
• Meteorological Users
• U.S. National Weather Service
• International Weather Service facilities
• Central America, South America, Pacific Islands,
  Mexico, Canada

7
SYSTEM USAGE ELIGIBILITY

• GOVERNMENT USER
• FEDERAL, STATE, LOCAL INTERNATIONAL.
• ENVIRONMENTAL MEASUREMENT DATA
• DATA OF INTEREST TO GOVERNMENT ENTITIES
• DATA SHARED WITH OTHER GOVERNMENT USERS.

8
BENEFITS

• Low-Cost
• Low-Maintenance
• Emergency Event-Driven Capability
• Ideal for Remote Locations
• Data Easily Shared Among Government Users

9
DRAWBACKS

• Finite Capacity (Approximately 133 Domestic
  Self-Timed Channels)
• Scheduled Transmissions based on Channel/Time
  Availability
• Interference Detection Difficult
• Troubleshooting capabilities Minimal

10
DATA DISSEMINATION METHODS

• DCS AUTOMATED PROCESSING (DAPS)
• Telnet or Dial-up Modem
• DOMSAT (Commercial Communications Satellite)
• DRGS (Direct Readout Ground System)
• GTS (Global Telecommunications System) Network

11
ENHANCEMENTS

• High Data Rate Transmitters (300 or 1200 bps,
  compared to 100 bps)
• GPS Clocks
• Better Timing
• Smaller Windows
• Result More Assignments

12
ENHANCEMENTS

• MORE EFFICIENT SYSTEM USE AGREEMENT
• LESS PAPERWORK MEANS FASTER PROCESSING
• SUA VERSUS MOA MAY MEAN LOWER USER APPROVAL
  LEVELS (I.E. FASTER PROCESSING)

13
ENHANCEMENTS

• MORE INFORMATION AVAILABLE ON WEB PAGES
• APPLICATION FOR SYSTEM USE AGREEMENT
• REPORTS
• GENERAL AND TECHNICAL INFORMATION
• TROUBLE REPORT AND ASSIGNMENT REQUEST TEMPLATES

14
CONCLUSION

• DCS IS A FINITE RESOURCE, BUT MORE EFFECTIVE
  MANAGEMENT TOOLS, IMPROVED TECHNOLOGIES CAN
  STRETCH THE CAPACITY IMMEASURABLY.
