Iran to build two new satellites

Iran's Aerospace Organization plans to build two satellites namely Pars 2 and Qaem, the caretaker director of the organization Hamid Fazeli announced on Sunday, the Mehr News Agency reported.

"Remote-sensing Pars 2 satellite and ...telecommunications Qaem satellite will be launched into space (in the future)," Fazeli said.

Pars 2 satellite will be designed for a period of three years in use and can take pictures with 5-meter resolution, he noted.

Pars 2 and Qaem satellites will orbit at an altitude of 600 and 3,600 kilometers above the Earth's surface respectively, he explained.

Fazeli said Iran has difficulties obtaining satellite images and these images are provided by other countries.

Using Pars 2 satellite, Iran can have its own satellite images, he added.

He went on to say that the manufacture of Pars 2 satellite will be completed by the next 4 years.

He said that Amir Kabir, Navid or Zafar are also remote-sensing satellites but the images taken by them are low resolution and are not efficient.

There are four types of resolution when discussing satellite imagery in remote sensing: spatial, spectral, temporal, and radiometric.

Spatial resolution is defined as the pixel size of an image representing the size of the surface area being measured on the ground and it is determined by the sensors' instantaneous field of view (IFOV). Spectral resolution is defined by the wavelength interval size and the number of intervals the sensor is measuring. Temporal resolution is defined by the amount of time that passes between imagery collection periods and radiometric resolution is defined as the ability of an imaging system to record many levels of brightness.
