ISRO Indian Satellites List
ssc preparation, important competetion questions, current affairs of india, latest question asked in competetion papers,
before we look into the list of Indian Satellites, let’s quickly learn few trivia about Satellites.
#1. What is a Satellite?
Anything that orbits something else like the moon orbits the earth, is known as a satellite. They are used for diverse purposes such as weather forecasting, television broadcast, radio communications, internet communications, GPS, etc.
Generally, there are two types of satellites
- Natural (Moon orbiting the Earth)
- Artificial (International Space Station orbiting the Earth)
There are many natural and artificial satellites, out there in space, performing their functions and making our lives back on earth easy in some or the other way. The artificial satellites as the name suggests are man made satellites from different countries.
Let us look at the year – wise list of Indian Satellites with their purposes and also learn about the organisation responsible for the Indian Space programmes.
