GOES DCS History / Evolutionary Development



The GOES Data Collection System (DCS) began operating in the early 1970's, but it origin's trace back to the mid/late 1960s with the Application Technology Satellite (ATS) that will celebrate its 50th anniversary on December 7, 2016. The ATS was the forerunner of the GOES program.

Many of the people involved in the evolution are retired or planning to retire, so to document the progress we've made and to provide a roadmap for future development efforts, we decided to capture the significant steps the program has made. It turned out to be quite a task! We recognize that a lot of the progress has been made by you, the users, so enjoy this walk down memory lane with us, and give yourselves a big pat on the back. But don't get complacent, keep up the good work!

We enjoyed doing this project but if we missed something please notify us of the event so it too can be captured for the record.
