Space systems to Iran for "Fajr" and "Ambassador" + photo

The defense and security of the East, as officials have announced that it will launch several satellites Fajr machinery. In line with the peaceful use of space and take advantage of experts in various fields of satellite data to build and launch its space program and operate Mahvrah has a different agenda. Obviously, the actual testing experience and technologies necessary to ensure performance of the user satellite systems that are used to reach large and heavy that it utilizes a small satellite and perform the lower circuits be.

Sina satellite was Iran's first satellite launched by Russia. Cena made jointly by scientists and experts from Russia and shared experience between the two countries to enhance local expertise and familiarity with the achievements of the leading countries in space. Iranian satellite Sina was in row 44 countries have placed a satellite in space.

Part of the Iranian space program given the expertise available in Iran Electronics Industries (Saayran) were set upon the first study, design and build the country's first indigenous satellite, called Omid, satellite after Fajr, in step The next morning the four satellites and satellites in the next important step Sepehr bark as a satellite altitude is higher and heavier than previous models. It hopes to launch satellites and satellite launch Fajr is also ready.

The country's space program with a realistic approach and relying on domestic power, it was necessary to be taken from other parts of the country also means that the most important task of the study and develop various technology and design and build space satellites Students were responsible for them in any of several technology and professional achievement and testing will be utilized. One of these families mate satellites satellite observations of Malek Ashtar University, the University of Science and Technology pointed out promising and Zafar. -1 In the observations of satellites launched this year and successfully completed its mission well, and some other satellites, such promises are ready to launch a satellite, according to the Festival will launch the satellite in turn.

The announcement is near the time of Fajr launch satellites in the report introduces and explains some of the achievements and a comparison between it and hope and observation satellites have been launched so far, we have -1.
Although these satellites may not have high accuracy but their individual rings of a chain and the acquisition of mature technology and systems that are integrated into Windows and is managed in a clear technology roadmap and product acquisition.

The hope was to lead the Fajr

Fajr TV satellite with professional design and is of hope emerged from the satellite. Omid satellite close to 90 days (three months) in space and about 1200 times the Earth's rotation. National Memorial as the first indigenous satellite, satellite and the mission defined for the part of key technologies in an operational satellites found. These technologies for the first time in its native form was used to include the production of electronic equipment such as satellite, radio production space flight simulation technology, satellites, space systems engineering completely native, the existence of satellites in orbit, specified time period and the rise of high-precision satellite, telecommunications (telemetry), remote command (Kamnd traps) were satellites.

A scientific research and telecommunications satellite Omid national satellite was that it defined the mission profile of the separation of the satellite orbit satellites, communication satellites and ground station double to store and send data, telemetry and tele Kamnd, send the command satellite ground stations and some other items were defined.

Fajr satellite

With a very valuable experience and break the bounds of hope very much that satellite, satellite in the next step with new features alongside the promotion of satellite capabilities were considered promising. The outcome of this process, satellite TV Festival that features a professional needs.
The main differences and improvements compared to the Festival of Hope, to benefit from solar cells to recharge batteries and power production, taking place in higher orbits, much greater longevity, with a cargo of imaging and the ability to increase the height of land through the transfer orbit is.

Fajr on the satellite body and solar cells has been used to charge batteries that supply power from the sun and its role in increasing the working life has been a year and a half. The GPS satellite system is a satellite positioning system to determine at any moment in space and positioning can have various applications and operational staff. The satellite also has the capabilities and imaging Manvrmdary.

Fajr satellite features and achievements

According to the East, the satellite in less than a year to different parts of the country and in collaboration with the aerospace industry was built and then enter operational testing procedures.
Mission intended for satellite orbit transfer Fajr, photography for mapping and meteorological research and has some shipments. Fajr tested and verified using satellite technology used in satellites and the next may Zyrsamanh improve processing and increase the height and the orbital lifetime of satellites Fajr duties will be.
New technologies such as satellite orbital transfer technology to help extruder cold gas, the technology of satellite monitoring of the stability of the active drive, imaging technology, space technology and electric power distribution is determined.
Including satellite Fajr gains can be achieved thorough the process required of all Zyrsamanh in space technology, reducing launch costs by achieving orbit transfer process in Mahvrah, making the first indigenous satellite orbital transfer capabilities noted.

Orbital transfer

Given the limitations of current rocket satellite carrier in the country, only to put down the orbits of satellites available. Also in the mountains close to the ground because of satellite collisions with air molecules have kinetic energy loss and loss of height over the fall and it inevitably ends the mission. The remaining operating satellites in orbit Khrrj force from the center of gravity is shifting speed of the earth are in balance. Drop rapidly with the opposition force of gravity and thus also declined to be drawn toward the Earth satellite.

Working to increase the life time of the satellite in orbit, a low-cost solution, transfer orbit satellites to deliver higher altitudes (the ratio of capital to upgrade the satellite to reach this height). In this method, after the initial placement of satellites in orbit using the built-in propulsion force generated by the satellite's orbit begins to increase at higher altitudes and can be deployed.

Space propulsion systems for general electrical and chemical propulsion systems are divided into two general categories. The chemical propulsion systems, energy to produce thrust force (thrust) stored in the extruder, which forces the release of chemical interactions, and then passing it to the extruder by the high speed of the exhaust gas (nozzle) acceleration takes.
Conventional chemical propulsion systems, including systems of cold gas and hot gas systems are satellite cold gas propulsion system design and construction projects have been carried out at the Aerospace Research Fajr used in satellites and satellite systems in orbit to move helps.
Cold gas systems such as nitrogen gas or compressed gas inlet Ranshgrhayy such high pressure hydrocarbon gas such as propane works. The compressed gas is stored in the tank on the satellite.
After the Fajr satellites in orbit around 350-375 km and a perigee height of the oval with 55 degrees of tilt of about 250-275 and beginning propulsion, orbit satellites in circular orbit 375 to 400 kilometers, reached a peak and the satellite With the departure of former elliptical orbit and the non-reducing and increasing the height of alternate, less prone to loss of energy and air resistance forces are dealing with. This action causes the upper atmosphere of ballistic space that was very thin and very low levels of air molecules that reduce the drag forces on the satellite velocity is significantly lower. Thus, increased shelf space satellites and from about 3 months of a one and a half years to come.
In addition to increasing the lifetime of the satellite, data, knowledge about the performance at higher altitudes to the satellite and its Zyrsamanh these heights will also be added to smooth the way for next experiments.
In addition to the cold gas propulsion Zyrsamanh, satellite Fajr of an extruder extruder pulsed plasma electric shock is very high, especially as a secondary cargo that utilizes satellite around the center of mass will cause the new extruder.
The rotational motion of the satellite rpm Fajr six satellites are used for stabilization. This balanced approach to sustainable building satellites advantages including simplicity, resisting disturbing forces and disturbances during the gyroscopic effect and input to the system with the operation of the satellite orientation is simply to keep the rest. Fajr once every 10 seconds around the satellite and rotates 36 degrees per second.
The consolidation of the three methods are also used in satellite Fajr.

Satellite Camera Festival

According to the East, one other important feature of this new Iranian satellite, advanced camera that images can be used in different centers will receive a response. For various imaging applications such as studying the situation, including meteorological applications, the camera images.
Design, fabrication, assembly and programming of electronic parts, mechanical parts manufacturing standards, spatial coverage of mechanical parts, optical parts using spatial coverage, and coating (Coating) lens with anti-glare glass, optics assembly parts and assembly commissioning of the camera, taking pictures using the camera and the optical experiments performed on different parts of the main activities for the construction of the new Iranian satellite is the camera.
This camera has a resolution capability of up to 500 meters.However, according to CEO Saayran camera resolution of 20 meters is also available for Tolo TV has been considered. Images taken by cameras mounted on satellite meteorology and mapping activities can be used for Fajr.
The Fajr satellite capabilities using a combination approach that includes two methods for positioning using ground stations and global positioning systems (GPS) satellite is inside. Iran Electronics Industries researchers to design, build and test spatial GPS receiver for positioning in LEO orbits (LEO) satellites have been in this type of system is used. Thus, in addition to the satellite to test various systems, such as positioning in space also carry out professional work.

Festival of satellite geometry 49 cm and width 35 cm height hexagonal face lift and has a mass between 50 and 60 kg. Festival of Hope twice and three to four times heavier than -1 is observed. Satellite observations of 15.3 kg -1, although the country's first satellite equipped with solar cells and also supplies imaging resolution is 150 meters, but given the short life of less than 1 and the two-month observation and experimental research satellite from its launch with Fajr Minimum life of one to one and half years as the country's first satellite into account the practical machinery.

Hope satellites and satellite-based observations of the Ambassador throw -1 and 250 km elliptical orbit with a perigee height of 350 and was named ambassador to the Festival with improved portability of about 50 kg of cargo which the ambassador -1 without the I will have the same circuit. Also increases with height through the orbital maneuvering in orbit 400 km circular Fajr (almost constant distance to the ground) will be.
So Fajr -1 satellite to observe professional and will be operational. Both satellites orbit the ability to generate power with solar cells are enjoying.
Festival of the satellite thermal insulation layer and a coating layer is used. The internal heat transfer and thermodynamics in the satellites with respect to extreme temperature differences between the various funds back into the sunlight and are therefore very complex satellite motion also another factor in addition to increasing the complexity is for the establishment of It is also equipped with advanced sensors, satellites in orbit long and too heavy for efficient scientific work of satellite thermal conditions have been carried out by the country's elite young professionals.

Fajr satellites now all tests before launch, including compliance with policies and to perform satellite launch is located on the first turn.
Although satellite Fajr in the category of small satellites is classified, but the style and look to approach leading countries in this field indicates that the interest of large and heavy due to advances in satellite manufacturing and less Zyrsamanh small and lightweight A large number of small satellite constellation to a few hundred kilometers altitude, but for many applications they use. In Iran, according to satellite development problems with portability Brhayy very heavy shipments to the high altitudes of the solar system now in light of high altitude satellites located at the dawn of the satellite are designed in the same direction. Given that satellite Fajr and before sunrise is the beginning of the third eye on Iran would be at high altitudes.

TV on the ambassador Fajr

The east, satellite TV transmissions from ground level to the Picture Gallery and the desired orbit with high accuracy and the optimal angle to deliver. With the development of missile technology in the country and enjoying the experience obtained in the two-stage Safir rocket carrying an experimental design and the necessary reforms as a type of rocket Safir Omid satellite base board the satellite entered service, and hope to 27 kg speed was more than 8100 meters per second in orbit.
The necessary steps for developing the space program needs to move heavier satellites into higher altitudes, there is most prudent to work on improvements to the existing satellite capacity is needed to achieve.
It also states the space satellite completed its new board based on their availability are examples of improvements that this method of reducing costs, reducing design time and testing, and the operational reliability and reduce the risks is desirable.
In this regard, various improvements have been named Ambassador Ambassador A and Ambassador -1 -1 -1 B were developed as a satellite on the ambassador observed that the ambassador was also observed Nanvmahvarh 15.3 kg -1 and at a height a little more hope Another showed its high efficiency and reliability. So get with satellite observations and the desired orbit, this category of countries that Mahvarhbrhay made by the aerospace industry, as well as stabilization and Reproducibility was tested.

Also, being a two-stage Safir satellite also features family board is superior to that country with little experience in the field space is very significant. Both of these types of liquid fuel and propulsion technology thrust vectoring control (TVC) are. During the first stage rocket Ambassador approximately 4.5 times length of second stage (excluding the holder of the satellite) is. Blades mounted at the end of the fixed body and the stability of the rocket with the help of aerodynamic forces are responsible.

The two-stage missile, satellite, Ambassador

The first stage propulsion thrust at the base of almost 9.5 times the thrust produced Safir second stage engine performance at the first stage is almost 2.1 times. With finishing the first stage propulsion, the engine along with all relevant sections of the hull structure and a large part of the rockets and missiles being lighter, it will continue escalating to the desired position. The first stage nozzle control system of fixed and moving blades in the second stage nozzle (gas engine) will change the angle. Any system for more accurate placement of satellites in orbit high precision and advanced technology with the backing of the scientific and technical knowledge in the field of dynamics and control is very high.
With improvements to engine satellite Safir Omid satellite on top of that row is the best engine, the engine of the second stage of the Safir Omid satellite Anrzhyky index has been higher. The index of characteristics of the motor control of the satellite is high.
The optimization of the engine while maintaining the strengths of the second stage engine has been trying to reduce fuel consumption engine ambassador hope, the satellite payload to be increased. Mobility during the engine combustion chamber, far above the capabilities of the outstanding pumps that engine optimized generation of phase two of its ambassador, and there is hope.
The thrust engine increased from 32 to 37 tonnes (increase of 50 percent in weight and 25% in height) to carry satellites weighing 50 kg to 250-400 km elliptical orbit for this satellite also has a diameter of 22 meters 1.25 meters has occurred.

For more explanation about the difficulties of designing and building a completely new engine will be the need to implement all phases of the study design, all kinds of tests should be performed on new propulsion to ensure the desired result. For example, given that the output speed of the rocket motor compressible gases (Compressible) they have the ability to vibrate. Unfavorable to the nature of vibrational modes in the gas entering the nozzle (Rocket exhaust), fuel-containing tubes, valves, fittings and structural vibration and missiles have also emerged in the case of resonance (Resonance) satellite, the rocket will be lost. So all the complex calculations of fluid dynamics, heat, most states must also be implemented for specific structures which in turn was very time consuming, and then build a prototype to be tested.

Given the need to perform detailed and thorough examination that some of them have cost over a million dollars, various countries, especially developing countries to achieve the improvement and development of a suitable propellant such as cluster and ways to (using There are a number of propulsion together), they can upgrade their board satellites such an approach in our space program is also on the agenda.

Our space program so far has been a good process and the process moves forward faster than many countries in world space. It is hoped that with the increasing development of satellite technology in the country to build up a sufficient number of samples required of them leads to better and stronger board the satellite were also available (eg satellite Brhayy satellites with the The launch of space in each) and in our space program from the operating results are more favorable rate.

不是的

这个发射率有超过日本的趋势

伊朗航天局局长哈米德·法则利(Hamid Fazeli)在电视节目介绍『黎明号』卫星发射任务。

Now in a talk show head of Space Organization said we planned to put both Navid and Fajr in "Ten Days of Dawn" (Dahe-ye-Fajr, 1 to 11 Feb) , Navid was ready and we launched it into space on predetermined schedule, but time of launching "Fajr" isnt clear yet, Maybe launch it before the end of this year (Iranian year which starts at March) or Maybe launch it after end of this year. We should accomplish all needed preflight tests of Fajr to be sure it is ready for launch.

He said weight of Fajr is around 60 kg and will be launched by Safir-1B too.

不错，伊朗还是有两下子的。

伊朗这样搞有前途,还是要自己掌握核心技术才行。

可惜都是很小的卫星，几十千克，没撒高性能的功能，象征意义大，火箭还是太小了。。

会不会太疯狂了，比印度还”有声有色“

France.  All four Diamond-A.

Iran to Send Heavy Satellites into Orbit


（图片来源：http://media.farsnews.com/Media/9003/Images/jpg/A0108/A1086962.jpg）

TEHRAN (FNA)- Iran plans to send heavy satellites into orbit and is setting up a new launch base for this purpose, Iranian Defense Minister Brigadier General Ahmad Vahidi said.

Vahidi said Thursday that the base will be used to launch one-ton satellites into an orbit of 1,000 kilometers.

He said that among Iran's next year plans was the launch of Tolou (Rise) and Fajr (Dawn) satellites into orbit.

Vahidi also said that Iran is planning to launch satellites into orbits of up to 36,000 kilometers next year.

Last Friday, Iran successfully sent Navid-e Elm-o Sana'at (Promise of Science and Industry) satellite into orbit.

The 50-kilogram orbiter lifted off into space with an orbital angle of 55 degrees on the Iranian-made Safir satellite-carrier.

The Islamic republic, which first put a satellite into orbit in 2009, has outlined an ambitious space program and has, thus far, made giant progress in the field despite western sanctions and pressures against its advancement.

Didn't M-ATF say that they mentioned on TV that it was delayed due to bad weather? Right now it's extremely cold and freezing/snowing in most of Iran.

Iran to launch home-made satellite in 3 months

ISNA - Tehran
Service: Foreign Policy


TEHRAN (ISNA)-Iranian Defense Minister Brigadier General Ahmad Vahidi said Wednesday Fajr (Dawn) satellite would be sent into space by the next three months.

Also regarding the return of the second Iranian flotilla from the Mediterranean Sea, he said, "The mission was conducted in high seas and everything was done well. This activity would continue."

Iran has always resisted against what enemies have tried to impose, he told reporters on the sidelines of the cabinet meeting.

The Islamic Republic of Iran has always declared that it defends itself against any threats, he said adding the Islamic Republic of Iran has never sought war, but it would always support its positions.

Fajr is a measurement and imaging satellite that will examine subsystems used in previous satellites. The manufacturing work of the satellite is still underway and nearly complete. The national Fajr satellite will be placed in elliptical orbit of 400 km in radius and will remain in space for a year and a half.

On November 12, 2011, Vahidi said that Fajr would blast into space with the thrusting power of "Safir-e-Fajr" satellite carrier.

Iran launched its first domestically-developed satellite, Omid (Hope), in 2009, an effort that made the Islamic Republic the ninth nation with the capability to launch satellites.

Iran is one of the 24 founding members of the UN Committee on the Peaceful Uses of the Outer Space, which was established in 1959.
