“Simorgh and Qaim” satellite launchers stabilize Iran’s heavy satellites in Leo orbit – rahnam

According to the Space and Astronomy Correspondent of rahnam News Agency, one of the space developments of our country in recent years is the launch of lightweight satellites into the Leo orbit, which we have been able to stabilize in this Earth orbit with the help of the three Noor satellites and the Khayyam satellite.

After stabilizing Iran in this orbit by means of satellites less than 50 kg, based on the 10-year space document, it seeks to stabilize in this orbit by means of satellites heavier than 50 kg. It seems that like the Qaim satellite carrier, which was the main player of Iran in the field of stabilization in the Leo orbit, the launching of heavy satellites and the stabilization of these satellites will also be the responsibility of the Simorgh and Qaim 100 satellite carriers.

Simorgh satellite carrier, a multi-stage satellite carrier built by the Aerospace Organization of the Ministry of Defense, which was unveiled on 14th of Bahman 1388, on the National Space Technology Day and the first anniversary of the launch of the Omid satellite. This satellite carrier was launched for the first time on April 31, 2015 from the Semnan space base for a suborbital research flight.

Simorgh satellite carrier uses both liquid and solid fuels. The total duration of Simorgh’s flight to reach the near-Earth orbit is about 490 seconds, and it has the ability to place a 250-350 kilo satellite in a 500-kilometer orbit. This satellite carrier is assembled vertically on the launch pad.

The moment of the successful launch of Simorgh

A successful mission to inject the satellite with Simorgh requires 490 seconds of successful operation of engines, turbopumps and other subsystems. In the second launch of Simorgh, only 120 seconds had passed since the failure in the second stage caused the failure of the launch, but in the third launch, out of the required 490 seconds of performance, the satellite carrier operated for 450 seconds without a fault, and in the third launch, this number even increased to 475 seconds. It arrived and the satellite carrier suffered a malfunction only in the last 15 seconds of its operation.

These numbers give the launches a success rate of 25, 92, and 97 percent, respectively, which is a clear sign of the increasing reliability of the Simorgh’s performance.

In relation to this matter, Seyyed Ahmed Hossein Mons; Spokesperson of the Air and Space Department of the Ministry of Defense He told rahnam: “The Simorgh satellite has completed most of its research stages and the data from the research launches have been collected.” Hopefully, in the rest of the year, we will have the final launches of this satellite carrier. With this satellite carrier, we will be able to launch 250 kg objects at a distance of 500 km, which can be in the form of one satellite or several satellites. If we consider the dimensions and size of the satellites that were launched with Safir or Qased, we can launch 10 of these satellites with Simorgh.

In addition to Simorgh, Qaem 100 is another satellite carrier designed to launch heavy satellites. Ghaem 100 is the country’s first three-stage solid fuel satellite, which was built by IRGC Aerospace Force scientists. This satellite carrier with three stages of solid fuel will be able to place satellites weighing less than 100 kg in the orbit of 400 to 500 km from the earth.

Launching Qaem 100 satellite

The sub-orbital launch of Qaim 100 satellite carrier of IRGC Aerospace Force was successfully carried out. Also, this satellite carrier is supposed to launch Nahid 1 satellite as well. Earlier, the Minister of Communications had announced Nahid Yak is a telecommunication satellite built by the Iran Space Research Institute and of micro class with the ability to send and receive data and voice in the ku band and three-axis control and some other space mechanisms. Such a satellite will be injected into the orbit for the first time, God willing.

Of course, in addition to these 2 satellite carriers, the construction and development of other satellite carriers such as “Sirir and Zul-Janah” that can inject heavier satellites is on the agenda of the Iranian Space Organization, the Air and Space Department of the IRGC, as well as the Air and Space Department of the Ministry of Defense.

It seems that in the cooperation of these 3 groups and based on the detailed roadmap of the country’s space industry, the stabilization of Iran in the Leo strategic orbit by means of heavy satellites similar to what happened in the field of light satellites will happen in the near future.
