  1. DCP COMMAND …bringing two-way communications to your DCPs

  2. Before its too late!

  3. DCP COMMAND

  4. How does it work? • The DCP COMMAND operates through the existing satellites on the old DCP I channels. The uplink originates at Wallops Island. • A gateway at Wallops provides a way for users to send commands to their DCPs. The gateway performs authentication and security to control and regulate what commands are given to DCPs. • In the field, a DCP COMMAND receiver connects to your DCP. The receiver listens for COMMANDS and communicates to the DCP using a standard protocol/interface. • The command format allows for individual and group addresses. This allows a single command to affect all the DCPs in a group. • The protocol supports predefined commands for common operational and maintenance functions. All manufacturer DCPs can support the same commands. A file transfer command allows for vendor specific data to be sent to a DCP. • Replies are made on DCP channels set aside for DCP COMMAND or on normal DCP Channels

  5. How much can you save with two-way? • One customer with a 2 way system estimates they send 1 command a week for every 50 sites. • If each command eliminates the need to visit the site and it costs $250 on average to visit a site, remote commands in a system of 200 stations, save $1,000/week, $52K/yr. • Scale this to the entire GOES DCS with 20,000 active sites, the system is likely to have 400 commands a week for a saving of $100,000/wk -- $5,200,000/yr.

  6. DCP COMMAND makes the impossible possible… • DCS is currently trying to free up 100 bps channels for their reassignment as 300 baud channels. • Currently it takes months even years to get a channel reassigned. • Imagine doing the entire system in a day. • DCP COMMAND makes it possible! • DCS may already be too big to manage without DCP COMMAND and it is only getting larger!

  7. What would You Do with 2-way communications to your DCPs? • Request missing data? • Request additional data? • Adjust transmission settings? • Change alarm thresholds? • Adjust data collection settings? • Perform Remote Diagnostics? • Request special transmissions?

  8. Other possible uses … • Want more timely data during floods and other extreme events? With DCP COMMAND you can get current data from DCPS when you want it. • Need to communicate with a technician in the field? DCP COMMAND let’s you do it. • Want a digital picture from a DCP? DCP COMMAND can give it to you.

  9. Is it safe and reliable? • The communications protocol is designed to insure the DCP receives error free messages. • The system will never pass to the DCP a command that has not been checked for errors and authenticated. • Error checking includes error detection codes with an undetected error rate of less than 1 error in 10^10 bits. That’s less than 1 error in the lifetime of the system. • The communication link is designed to operate with low gain antenna and use a minimum of power.

  10. How is DCP COMMAND different from DCPI? • More throughput -- 300 baud vs 100 baud • More data – up to 64K bytes vs 12 bits • More reliability – 10-10 error rate vs high error rates • More security – message authentication • Predefined and standard functions • We could live without DCPI – we can’t live without DCP COMMAND!

  11. Schedule • Jan 2007 – Complete specifications for DCP COMMAND Receivers. • Jun 2007 – Complete specifications for gateway system. • Jan 2008 – Complete Prototype Receiver/DCP and Gateway development. • Jun 2008 – Complete demonstrations, verification and validation tests. • Jan 2009 – Complete Beta Receiver/DCP and Gateway development. • Jun 2009 – Complete verification and validation tests.

  12. What can you do? • Complete the questionnaire • Talk with us about your own needs and concerns. • Get behind the effort • Realize that this is our last chance to get two-way because of NTIA
