One checkbox implementation in web interface.
One checkbox implementation in mission control web interface - real-time data for orientation vectors for ground station antenna. == Same xml file used for visualization of a CubeSat trajectory, also used to feed antenna control. TRA application now can accept data in XML format from a remote, dynamically created "initial" position, and post results of trajectory calculations back to the same or even different server. That future allows to calculate trajectory and engines firing time in parallel via distributed calculations network. Probably the same mechanism can be used in screen saver app. details on http://www.adobri.com/SatCtrlR.aspx
