Dousti / Dushanbe - Earth Observation
Dousti satellite, is another homegrown production, which passed the pre-launch tests and is ready for launch. Literally means ‘friendship’, Dousti satellite is manufactured at the Sharif University of Technology. Over 150 experts in different fields of electronics, aerospace, computer science, mechanics and industry from five faculties manufactured the satellite.
The satellite takes images with better than 30 meter resolution, investigate of vegetation and monitors water resources. Dousti will be placed into the orbit 500 kilometers above the earth’s surface. Iran has launched several short-lived satellites into orbit over the past decade, including the Simorgh and the Pajouhesh.
While the secondary purpose of these two Iranian satellites is imaging, the satellite also has a telecommunication mission message that needs to store a message and transmit it to Earth; in addition, the message satellite has a space-measuring radiation cargo. So the satellite of a mission and mission satellite has three missions.
The satellite Dushanbe was designed and developed by Sharif University of Technology as one of the country's largest satellite technology development satellites and the employer of the Space Organization of Iran. Technology development projects are defined and implemented to provide technical knowledge and experience in areas related to spatial technology, as well as the entry of universities into this field with the training of specialist personnel.
In this regard, the Friendship Satellite is specially designed and developed to develop and access technologies that were first installed and used on indigenous satellites. These technologies include three-axis control, an OBDH-resistive fault, a semi-active heat control system, and solar-powered solar cells that can be exploited in space.
The maximum lifetime of this satellite is one year and its ballistic life will be proportional to its orbit. The satellite has a mass of 52kg and is considered a microsatellite due to the massive classification of satellites. The orbit of this elliptical orbit, in the category of low-level circuits (LEO), with peak altitudes and perients, is 310 and 250, respectively, and orbit will be 55 degrees.
The satellite is almost cubic and dimensionally in the range of half a meter and does not have the propulsion force to perform orbital maneuvers and change circuit; therefore, after deploying in a predetermined circuit, the missions carried out during the lifetime After expiration of operational life, it enters the atmosphere with the loss of kinetic energy and descends to lower circuits and ends with life. The energy required for this satellite comes from the use of batteries and solar panels.
On the space technology day, three major achievements in the field of space were unveiled at the presence of the president. According to the October report, three important achievements of the space industry of the country were unveiled at the same time as the Space Technology Day and the third day of the decade of Mubarak Fajr. Hojatoleslam Hassan Rouhani attended the summit of the "Dusati" satellite satellite .
At the ceremony, Ali Akbar Salehi, head of the Atomic Energy Organization, Minister of Communications Mahmoud Vaezi, Mohammad Nahavandian, President of the Office, Vice President of Technology, Sorena Sattari, and the President met with senior officials. In the beginning of the ceremony, in spite of the technology day of space, a clip was broadcast on the activities of the Ministry of Communications in the development of Internet and mobile communications. This year's Space Technology Day was marked with the slogan "Balanced Development, A Future Forward".
Also, with the presence of the president of the Iranian Space Agency's Remote Sensing Laboratory and the Center for Satellite Assimilation and Testing, the Iranian Space Research Institute opened and launched. The Remote Sensing Laboratory had been designed and implemented at the National Space Center of Alborz and includes services such as spectroscopy, radiometry, calibration of space sensors and equipment.
The satellite in the class of micro-satellites with 50kg of weight is to be planted in the elliptical orbit. This satellite was built by the Iranian Space Agency. The satellite testing center was also designed and built to support small satellite services and space services development, and includes 9 laboratories and a space workshop in the field of construction and support. According to the Iranian Space Agency, more than 80 percent of the equipment of this center is designed by specialists in the spatial technology of the country.
