 Introduction and key terms  Background information  Design  Implementation  Challenges  Final Results

 Stabilized  High accuracy  Optical  Tracking  System ◦ A NAVSEA (Naval Sea Systems Command) telescope used to track satellites, missiles, and other celestial objects.

 User Datagram Packets  Connectionless Protocol ◦ instead of phone call  No error checking ◦ Faster data transmission ◦ Less bandwidth needed

 G – Graphical  U –User  I - Interface An interface that allows the user to interact with the computer using a mouse.

 Tool Command Language ◦ Easy string based scripting language  Toolkit ◦ Used with TCL to create the Graphical part of the user interface.  Platform independent. ◦ Build in Unix used in Windows

 Build the GUI to given specifications.  Connect all the devices together correctly and test each component.  Use the serial device server to reach video control switch.  Send commands to the video control switch over network using UDP and confirm results. Implementation Design

SHOTS TELESCOPE SYSTEM Video Control Switch Serial Device Servers Outputs Network

 Design Specifics: ◦ One input may have many outputs (Not vice versa). ◦ Load in configuration and labels files ◦ Save current configuration to a file. ◦ Communicate with a Serial Device Server over Ethernet. ◦ Display the current configuration in real time. ◦ Simplicity

 Unfamiliar with TCL/TK language in Linux environment. ◦ Normally used csh in windows  Networking ◦ Incorporating a networking feature into a program ◦ Working with UDP

 Sent out: “**Y, !!”  Receives:

 Hardware Problems ◦ Faulty cables ◦ Serial Device Servers  Can only be fully configured using Internet Explorer (IE).  Configurations have a tendency to change.  Reboot about every 6 hours. (Loss of Connection)

SHOTS TELESCOPE SYSTEM Video Control Switch Serial Device Servers Inputs/ Outputs Network

 Was able to successfully communicate with the server and switch.  Create the GUI with a few add-ons but still meets the specifications.  Documentation for testing and setting up the devices.  Serial Device Servers changed over to static IP.
