History of Indian space research:

Indian space research is the concept of Dr. Vikram Sarabhai, who has been called the father of the Indian space program. He became known as a scientific visionary and a national hero. After the launch of Sputnik in 1957, he realized the utility of artificial satellites. India's first Prime Minister Jawaharlal Nehru, who considered scientific development to be an important part of India's future, placed space research in 1961 under the supervision of the Department of Atomic Energy.

In 1962, 'Indian National Committee for Space Research' (INCOSPAR) was formed, in which Dr. Sarabhai was appointed as the chairman. After which, in 2003, Dr. Sarabhai participated in a preliminary study with NASA regarding the feasibility of artificial satellites to be used for multiple applications such as live broadcasting of television and it was found from the study that, This is the cheapest and easiest way to do it.

From the outset, realizing the benefits of bringing satellites to India, Sarabhai and ISRO worked together to develop an independent launch vehicle, which would be necessary to put artificial satellites into orbit, and build them into larger launch vehicles in the future. Was able to provide practice.

Types of Satellites in India

  • Biological Satellites: They are satellites which are generally used to carry living organisms for scientific experiments.
  • Astronomical Satellites: They are satellites used for observing distant planets, galaxies and other outer space objects.
  • Communication Satellites: They are satellites which are deployed in space for the purpose of telecommunication. Modern communications satellites typically use geosynchronous orbits, Molniya orbits, or low Earth orbits.
  • Observation satellites: Earth observation satellites or communications satellites are deployed for military or intelligence purposes. Little is known about the full power of these satellites; the government that operates them usually keeps the information related to their observation satellites classified.
  • Earth observation satellites: There are satellites which are used for non-military purposes like environmental monitoring, meteorology, map making etc.
  • Small Satellites: There are satellites of unusually low weight and small size. New classifications are used to classify these satellites: minisatellite (500–200 kg), microsatellite (below 200 kg), nanosatellite (below 10 kg).
  • Space stations: are human-designed structures for human beings living in and outside of outer space. A space station is distinguished by its lack of major propulsion or landing features to a spacecraft—rather, the other vehicles used as transport to or from the station. Space stations are designed to remain in orbit for intermediate periods, for periods of weeks, months, or even years.
  • Navigation satellites: are satellites that use radio time transmitted signals, which enable mobile receivers on the ground to determine their exact location. Relatively clear line of sight between satellites and receivers on the ground, Satellite navigation systems, combined with improvements in electronics, allows to measure the location of accuracy in real time, on the order of a few meters.
  • Test satellites: Several small satellites, mainly for experimental purposes. These tests include remote sensing, atmospheric studies, payload development, orbit control, recovery technology, etc.
  • Tether Satellites: They are satellites which are connected to another satellite by a thin wire called tether.
  • Weather Satellites: Mainly used to monitor the Earth's weather and climate.
  • Navigational Satellites: Satellites for navigation service to meet the emerging demands of civil aviation needs and user needs of location, navigation and navigation based on independent satellite navigation system.
