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.
IMAGE MOUNT CONTROL (COMPUTES LOCATION OF OBJECTS) GUI (OBJECT) GPS (TIME) The Current Hardware TELESCOPE (LOOKS AT OBJECTS)
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
IMC GUI MY SYSTEM IMC GPS The Time Setting System • Linux PC • Timer Card • C Code • TCL/TK GUI • Networking Feature TELESCOPE OTHER COMPUTERS
The Coding Language • Tool Command Language • ToolKit
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
Results • C program communicates with GUI and timer card • Time can be changed via GUI • Able to send and receive information from another computer
