Jakarta - Teleskop Radio Very Long Baseline Interferometry (VLBI) Global Observing System, or VGOS, is being built at Observatorium Bosscha by Institut Teknologi Bandung (ITB).
This is referred to as the first teleskop construction in Indonesia. ITB has partnered with Shanghai Astronomical Observatory-Chinese Academy of Sciences (SHAO-CAS) to support this effort.


Drawn from the ITB, VGOS can be used for astronomical research, geodesic mapping, scientific data analysis, lunar surface exploration, telecommunication, and many other applications. In addition, VGOS has the potential to create new, high-quality risets on both a national and international scale.

Telkomsel nantinya beroperasi di jaringan yang tergabung dengan beragam teleskop radio global, as per Kepala Biro Kemitraan ITB, Taufiq Hidayat. Even still, as of right now, VLBI is only present in the upper right corner.

In the equatorial zone and neighboring countries, this VLBI is still in the early stages of development. The only place where VLBI near Indonesia may be found is Brazil.


The VGOS Telescope's Features

VGOS is a telescope designed to observe high precision cosmic radio emissions. VGOS operates by aggregating data from multiple global telescopes.

From there, exact measurements of the separation between two telescope points will show up. Additionally, global movements can be tracked via VGOS.

VGOS is able to track movements over time or changes in distance from continents. Bosscha ITB's creation of VGOS will make Indonesia a baseline bridge connecting the northern and southern hemispheres.

Indonesia can make more contributions to the global network of radio telescopes in the future. Indonesia has yet another excellent opportunity to work with new partners.

"Thus, we can determine whether an area has dangerous potential or not," Taufiq said.

Regarding the environment, it is anticipated that VGOS will have the capability to observe the possibility of climate change. The earth's surface movement of points will be measured by VGOS, enabling it to be used as an extremely precise parameter.


Taufiq believes that VGOS will be a significant, long-term investment for Indonesia. He believes that Indonesia's research and standing in the astronomical community will be enhanced by the telescope.

 The Operation of Radio Telescopes

A radio telescope is an optical device used to examine naturally occurring radio radiation from stars, galaxies, black holes, and other celestial phenomena, according to the National Radio Astronomy Observatory website.

This telescope functions by first gathering visible light and then focusing it. After that, the light will be examined with a variety of tools.

Depending on the kind of radio waves they can detect, radio telescopes come in a variety of sizes and forms. Radio telescopes are larger than other types of telescopes, though.

 Light with wavelengths ranging from one millimeter to more than ten meters can be observed using radio telescopes. Every radio telescope has a receiver to pick up signals and an antenna mounted on the mount.

Radio Telescopes in Foreign lands

There's another radio telescope in Guizhou, China. Five-hundred-meter Aperture Spherical Telescope (FAST) is the name of the telescope.

According to the Space site, the FAST telescope's huge optical aperture extends up to 500 meters. FAST, which was founded in 2020, is sometimes referred to as the world's largest telescope.

Moreover, the SKA radio telescope is situated in South Africa and Australia. The dimensions of this telescope are 512 x 15 meters.

Even though none of these telescopes are as big as some of the earlier ones, a far larger building scale is planned. There are currently 200 stations in South Africa and 512 in Australia for the telescope.

ALMA is the name of another radio telescope located in Chile. The diameter of this telescope is 12 meters, or 39.4 feet.

The most remote oxygen in space was one of ALMA's significant findings. The telescope has already broken this record multiple times.
