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

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

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 GUIIMC
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

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
