Construction under LAPAN (National Space and Aeronautics Institute)  BRIN

9. Mount Timau Observatory under construction

10.  Will be the biggest optical telecope
in South East Asia and in near
Equator
 Altitude : 1300 m ASL
 Coordinates : 09o35’ South and 123o
56’ East
 Working wavelength : optical and
infrared
 Planned First Light : 2023

11. It is important to build our own
radio telescopes:
 Capacity Building
 Doing Science
o Astronomy
o Astrophysics
o Geodesy
o Atmospheric
o Geodynamics
Astronomy Education and Research in ITB
Motivation with radio astronomy; interdisciplinary fields
 Skill enhancement/ Technology /
Experiences, and so on
o Construct Radio Telescope
o Design/Produce receivers
o RFI Technology
o Cryogenics
o Time & Freq. stability
o ADC processing

12.  Global cooperation (Not only with Asia,
but also with Europe, Australia, North
America, Africa, and Latin America) to
make VLBI network
VLBI (Very Long Baseline Interferometry)
is a network of many radio telescope all
over the world to create a comparable
resolution with Earth size radio telescope.
Most spectacular result of VLBI is the
historical first picture of Black Hole
Astronomy Education and Research in ITB
Motivation with radio astronomy; interdisciplinary fields

13.  Considering conversion of
telecommunication antenna
 Multidisciplinary research with
astronomy (with FITB, STEI and FTMD)
 Radio Instrumentation
 Accurate time keeping
 Geodynamics, EOP
 Astrometry/astronomy (imaging)
 Software engineering
 etc
Astronomy Education and Research in ITB
Development of VLBI Radio Telescope with Indosat Ooredoo, Jatiluhur

14. There are many radio
telescopes in East Asia
mostly in nothern
hemisphere and some in
Australia and New
Zealand
There are no VLBI
telescope near the
Equator

15. In cooperation with Shanghai Astronomical Observatory
(Chinese Academy of Sciences), ITB will join the IVS
(International VLBI Service for Astrometry and Geodesy)
