Front End Data System (FEDS) Version 10.0

In traditional missions at NASA, ground systems were normally custom-built for each project. Additionally, there would be separate ground systems for each part of the spacecraft as well as a totally separate ground system for mission operations. Each of these generally interfaced through non-standard...
