  1. Taiwan Automated Telescope (TAT) at Maidanak Wang, Li-Han National Tsing Hua University, Taiwan

  2. Outline • Taiwan Automated Telescope Network • Issues from TAT Experience at Maidanak • Suggestions

  3. Taiwan Automated Telescope Network • It will consist of several fully-automated telescopes at appropriate longitudes around the world. • Current sites Hsinchu, Taiwan (test site) Teide Observatory, Tenerife, Canary Is. ,Spain Maidanak Observatory, Uzbekistan • Future sites Mauna Loa Observatory, Hawaii Yunnan Observatory, China …….

  4. TAT at Teide, Spain

  5. TAT at Maidanak

  6. Instrumentation • Fully automated system • 3.5 inch Telescope (Questar, Maksutov Type) • German Type Equatorial Mount (Takahashi NJP ) • 1024 * 1024 CCD (Apogee U6) • No any filters • Linux-based Computer

  7. Observer Linux-base Computer Internet WebCam CCD Electrical Box Equatorial Mount Enclosure Weather Station & GPS Procedure control control control control control control control eg1eg2eg3

  8. Outline • Taiwan Automated Telescope Network • Issues from TAT Experience at Maidanak • Suggestions

  9. Major Issues from TAT Experience at Maidanak (2007.07 – 2010.06) • Electric Power Stability • Internet

  10. TAT Power System • Stabilizer • Transformer(220V→110V) • UPS Total power consumption : < 2KW c s

  11. Power Stability Problems 1. Voltage Fluctuation 2. Power interruption (frequent, long, unexpected) Result in 1. More problems in electronic devices 2. UPS battery depletion (shortens battery life time) 3. Heater OFF → Low temperture → Battery Death

  12. Power Stability Problems 1. Voltage Fluctuation 2. Power interruption (frequently, long, unexpected) Result in 1. More problems in electronic devices 2. UPS battery depletion (shortens battery life time) 3. Heater OFF → Low temperture → Battery Death

  13. p Voltage Data from UPS (after stabilizer )

  15. Weather Data • Indication of power interruption

  16. Power Stability Problems 1. Voltage Fluctuation 2. Power interruption (frequently, long, unexpected) Result in 1. More problems in electronic devices 2. UPS battery depletion (shortens battery life time) 3. Heater OFF → Low temperature → Battery Death

  17. Major Issues from TAT Experience at Maidanak (2007.07 – 2010.06) • Electric Power Stability • Internet

  18. Internet Current status • Remote control • TAT web page • Webcam image (single frame) • Incapable of image transfer shell eg1eg2eg3 speed eg1, eg2 ,eg3

  19. Suggestions Infrastructure needs to be improved. • Power 1. Monitoring power stability 2. Solving problems of power instability • Internet 1. Capable of image transfer
