Reviewed by Moharam Gayathond, Head of Space Department at Electronic Industries Company of the Ministry of Defense (Sayran) and the director of the “Tolo 3” satellite project, on the sidelines of a ceremony Simultaneous launch For three Iranian satellites, historical background and development Iranian space industry Over the course of 20 years, he explained the complex challenges the country faced after placing the satellite in orbit, and announced the drive towards systems development as a final step towards space industrialization.

A simultaneous launching ceremony for three Iranian satellites into space was held at the Center for the Development of Intellectual Abilities for Children and Youth, in the presence of His Excellency the Minister of Communications and Information Technology, Mr. Sattar Hashemi, and officials from the Iranian Space Organization. During the ceremony, in which the audience witnessed the launch of satellites via… Video conferencing technology Using a Russian Soyuz rocket, he delivered Muharram Ghiyathund word.

At the beginning of his speech, Gayathund referred to the presence of scholars and students at the ceremony, saying: “We meet today on the occasion of the tripartite launch ofRemote sensing satellites Launched by the Ministry of Communications and Information Technology and the Iranian Space Organization, we are witnessing this event thanks to the support and perseverance of the Iranian Space Organization, under the leadership of Dr. Salarieh.”

Before delving into the technical discussion about satellites, the head of the Iranian space group referred to the historical background ofSpace science In Iran, saying:

“Although the beginning of the space age in the world dates back to 1957, Iranians and Muslims have a deep understanding of this field, specifically astronomy and space.”

He added:

In his book “Al-Masudi’s Law,” which was the result of thousands of years of astronomical data, he refused Al-Biruni The hypothesis of the centrality of the Earth and the rotation of the Sun around it. Upon his return from his trip to India, he calculated the radius of the Earth, and the number he obtained differed from the current accurate calculations by only 37 kilometers.

Stressing that the Iranians and Muslims have a great right in the field of space, Gayathond said: “Although the position we occupy today is valuable, we have not yet reached the true position we deserve.”

The director of the “Toulo 3” project continued his talk about the process of building a modern space industry in the country, saying:

“The Iranian space industry was established about 26 years ago, in both the Ministry of Defense and the Ministry of Communications. At that time, the Ministry of Communications began cooperating with foreign parties to develop satellites, and this applied research led to the launch of the first satellite of the Islamic Republic of Iran, the Sina satellite, in 2005.

He added:

Then, with the launch of the “Omid” satellite, the country’s first domestically produced satellite, in 2008, Iran joined the club of the ten space nations, meaning that it is a country that possesses a complete satellite launch cycle, a launch pad, and a ground control platform.

“Zalium, there are between 60 and 100 countries that have satellites, but this cycle is summarized in only 11 countries.”

“Today, we should know that than 35 satellites have been built and launched in our country,” he said.

In another part of his speech, Gayathund referred to the technical challenges following the launch, explaining:

“When a satellite is successfully placed in orbit, contrary to popular belief, the work does not end, the main work begins, and no one should think that the work is over. For a satellite to become operational, several important tasks must be accomplished after it is placed in orbit.”

The group leader continued They’re going to happen Satellite:

“The first stage is control; that is, the satellite must be able to establish a stable connection.

The second stage is evaluation, where all subsystems and the space platform are checked to ensure they are working properly.

The third stage is ensuring the proper performance of the software and algorithms, and in the fourth stage we enter the launch stage.”

He pointed out that this process usually takes between one and two months for satellites. From the moment the commissioning phase begins, thousands of systems and equipment must operate with complete efficiency, and if just one system malfunctions, while all of them are working at 99.9%, it becomes pointless and the mission fails, even with quality research, because the industrial work was not perfect.

Gayathund stated that working in space is very complex, and that technical teams face difficult days and nights, and said:

“During these two months, each of these steps must be carried out meticulously.”

The director of the “Toulo 3” project stated:

“Today there are various platforms in the world, including nanosatellite platforms, which are small cubesats weighing between 10 and 20 kilograms, used in research fields. Microsatellite platforms, which weigh between 10 and 100 kilograms, and mini-satellite platforms, which weigh between 100 and 500 kilograms:.

He continued:

“We achieved great successes last year; the Shamran 1 satellite was one of the small satellites that successfully passed the four stages and completed its space mission. This work was done with the support of the Iranian Space Organization, our brothers in the Revolutionary Guards Space Organization, and the Scientific Viceroy, who provided great support to knowledge-based companies.

This satellite has now been operating for 16 months, and for the first time we were able to carry out an orbital rendezvous maneuver, that is, bringing two objects in orbit closer together, which is a very important achievement that only four countries have been able to achieve.”

Regarding the current launches, Gayathund said:

“We are currently launching the “Zafar” and “Tolo 3” satellites on the third platform, which is the small satellite platform.”

Regarding launch pads, he said:

“We started with the Safir and Qasim missiles, and today we reached the Simorgh and Qaim 100 missiles. Installing the Simorgh missile, which has a payload of 250 kilograms in an orbit at an altitude of 500 kilometers, and the Qaim 100 missile, which orbits at an altitude of 100 kilometers, is the basis for activating and developing the country’s space sector.”

When asked what path to follow, he identified three basic steps for the future, adding:

“The first task is to stabilize the operating platform to ensure that the satellites are placed in space and stabilized. A

The second step is to carry out multiple space missions, even if that requires studying thermal effects, to increase reliability.”

The head of the Sayarian Space Group considered that the most important step is developing an integrated system, and he explained, saying:

“The third point is the necessity of developing an integrated system.” It would take three months to image the entire Persian Gulf with a single satellite, but a satellite constellation capable of doing this every three days would be needed. This requires operational and industrial efforts.”

And he announced:

“We have already started the constellation construction phase for this purpose, and we hope to start working on it by the end of this year.”

Regarding the “Toulo 3” satellite, Gayathond said:

“These satellites are equipped with telescope technology, and are considered advanced imaging satellites. We have wide-ranging activities in the country that are not affiliated with me or a specific company, but rather large sectors of knowledge and government companies participated in and supported them.”

He confirmed, saying:

“Most of the equipment on these satellites is home-made, sometimes this is the first time they have been launched into space, and the first use is always accompanied by some uncertainty.

In the world, these tests are usually conducted independently first, and then the results are announced after receiving them, but we, in coordination with… Dr. Salaré “And the Ministry of Communications, we accepted this challenge and the risks of transparency before full operation began.”

Concluding his speech, the director of the “Toulo 3” project said minutes before the launch:

“The truth is that we are facing difficult and anxious days. I ask you for your prayers, not as a scholar or an elite, but as a soldier.”
