Omid Satellite
Omid (, meaning "Hope") was Iran's first domestically made satellite. Omid was a data-processing satellite for research and telecommunications; Iran's state television reported that it was successfully launched on 2 February 2009. After being launched by an Iranian-made carrier rocket, Safir 1, the satellite was placed into a low Earth orbit. President Mahmoud Ahmadinejad supervised the launch, which coincided with the 30th anniversary of the Iranian Revolution; NASA verified the launch's success the following day. Its Satellite Catalog Number or USSPACECOM object number is 33506. Ahmadinejad said the satellite was launched to spread "monotheism, peace and justice" in the world. The ''Tehran Times'' reported that "Iran has said it wants to put its own satellites into orbit to monitor natural disasters in the earthquake-prone nation and improve its telecommunications." Foreign minister Manouchehr Mottaki said that Iran launched the satellite to "meet the needs of the country" and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iranian Space Agency
The Iranian Space Agency (ISA, Persian language, Persian: ''Sāzmān-e Fazāi-ye Irān'') is Iran's Government of Iran, governmental space agency. The Iranian Space Research Center and Iranian Space Agency are the main organizations carrying space research and operations in Iran. Iran became an Timeline of first orbital launches by country, orbital-launch-capable nation in 2009. Iran is one of the 24 founding members of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), which was set up on 13 December 1958. History The history of the space industry in Iran dates back to the late 1940s and early 1950s. Iran first joined the ranks of space technology users in 1960 by becoming a member of the International Satellite Communications Organization and installing and using a standard A antenna in Asadabad, Hamedan. In 1974, following the launch of the first US Earth Resources Survey satellite, which was later renamed the Landsat series, the Satellite Data Co ...

Tawhid
''Tawhid'' () is the concept of monotheism in Islam, it is the religion's central and single most important concept upon which a Muslim's entire religious adherence rests. It unequivocally holds that God is indivisibly one (''ahad'') and single (''wahid''). Tawhid constitutes the foremost article of the Muslim profession of submission.D. Gimaret, ''Tawhid'', Encyclopedia of Islam. The first part of the Islamic declaration of faith ('' shahada'') is the declaration of belief in the oneness of God. To attribute divinity to anything or anyone else, is considered '' shirk'', which is an unpardonable sin unless repented afterwards, according to the Qur'an. Muslims believe that the entirety of the Islamic teaching rests on the principle of ''tawhid''.Tariq Ramadan (2005), p. 203. From an Islamic standpoint, there is an uncompromising nondualism at the heart of the Islamic beliefs ('' aqida'') that is seen as distinguishing Islam from other major religions. The Quran teaches ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khayyam Satellite
The Khayyam satellite () is an Iranian high-resolution imaging satellite that was successfully sent into low Earth orbit on 9 August 2022. It was launched from the Baikonur space base in Kazakhstan, on a Russian Soyuz rocket. The satellite was designed by the Iranian Space Agency and built by Russian companies VNIIEM and NPK Barl in a contract that included technology transfer and providing technological assistance in future Khayyam satellite family designs by Iran. It is named after Iranian polymath Omar Khayyam. Specifications Khayyam is a satellite situated in an orbit above the Earth's surface. Its main purpose is to collect information and images from the Earth's surface with a resolution of 1 metre (3.3 feet). It is designed to monitor and investigate the Earth's surface, both for government and civilian purposes. According to the Iranian Space Agency, the life of this satellite is expected to be five years, the first four months of which will be spent undergoing t ...

List Of Orbits
This is a list of types of gravitational orbit classified by various characteristics. Common abbreviations List of abbreviations of common Earth orbits List of abbreviations of other orbits Classifications The following is a list of types of orbits: Centric classifications * Galactic Center, Galactocentric orbit: An orbit about the center of a galaxy. The Sun follows this type of orbit about the Galactic Center of the Milky Way. * Heliocentric orbit: An orbit around the Sun. In the Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris. Moons#Moons of the Solar system, Moons by contrast are not in a heliocentric orbit but rather orbit their parent object. * Geocentric orbit: An orbit around the planet Earth, such as that of the Moon or of artificial satellites. * Selenocentric orbit (named after Selene): An orbit around Earth's Moon. * Areocentric orbit (named after Ares): An orbit around the pl ...

Rasad 1
Rasad-1 (, meaning ''Observation'') was an Iranian satellite which was launched in 2011. Satellite The third Iranian satellite, and the second to be launched successfully using an indigenous rocket, Rasad-1 was Iran's first imaging satellite. Launched aboard a Safir-B carrier rocket, it was successfully placed into a low Earth orbit A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial object ... at an altitude of , inclined at 55.7 degrees. It made approximately fifteen orbits per day. Rasad-1 was launched on the maiden flight of the Safir-B rocket, designated Safir-B1, from a launch site in Semnan province, Iran. The launch occurred at approximately 09:14 UTC on 15 June 2011 with the spacecraft reaching orbit several minutes later. The satellite had a mass of and returned images with a ...

Telemetry
Telemetry is the in situ collection of measurements or other data at remote points and their automatic transmission to receiving equipment (telecommunication) for monitoring. The word is derived from the Greek roots ''tele'', 'far off', and ''metron'', 'measure'. Systems that need external instructions and data to operate require the counterpart of telemetry: telecommand. Although the term commonly refers to wireless data transfer mechanisms (e.g., using radio, ultrasonic, or infrared systems), it also encompasses data transferred over other media such as a telephone or computer network, optical link or other wired communications like power line carriers. Many modern telemetry systems take advantage of the low cost and ubiquity of GSM networks by using SMS to receive and transmit telemetry data. A ''telemeter'' is a physical device used in telemetry. It consists of a sensor, a transmission path, and a display, recording, or control device. Electronic devices are widely u ...

AFSK
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is encoded on a carrier signal by periodically shifting the frequency of the carrier between several discrete frequencies. The technology is used for communication systems such as telemetry, weather balloon radiosondes, caller ID, garage door openers, and low frequency radio transmission in the very low frequency, VLF and extremely low frequency, ELF bands. The simplest FSK is Binary numeral system, binary FSK (BFSK, which is also commonly referred to as 2FSK or 2-FSK), in which the carrier is shifted between two discrete frequencies to transmit binary (0s and 1s) information. Modulating and demodulating Reference implementations of FSK modems exist and are documented in detail. The demodulation of a binary FSK signal can be done using the Goertzel algorithm very efficiently, even on low-power microcontrollers.
