1 A Problem of Time and Telescopes By: Tyler Yoshiyama Home Institution: UH Hilo Mentor: Ross Matoi

2 Just the Wrong Time? AEOS pointed at Jupiter last week. Yesterday it failed to point at Jupiter. Today it points at Jupiter again.

3 The Current Hardware GUI (OBJECT) GPS (TIME) IMAGE MOUNT CONTROL (COMPUTES LOCATION OF OBJECTS) TELESCOPE (LOOKS AT OBJECTS)

4 My Project Design a system to input any time into the Image Mount Control (IMC) Independent of the IMC Doesn’t change code in IMC Tricks telescope

5 GPS The Time Setting System Linux PC Timer Card C Code TCL/TK GUI Networking Feature IMC GUI IMC TELESCOPE MY SYSTEM OTHER COMPUTERS

6 The Coding Language Tool Command Language ToolKit

7 Network Uses User Datagram Packets (UDP) to send data UDP is fast but doesn’t check for errors

8

9 The Roadblocks Had to learn to program in new environment Had to learn TCL/TK Driver didn’t compile initially Managed to debug problem by adding one line of code

10 Results C program communicates with GUI and timer card Time can be changed via GUI Able to send and receive information from another computer
