Some Basic Info About Isro

INTRODUCTION:

Pace activities in the country started during early 1960s with the scientific investigation of upper atmosphere and ionosphere over the magnetic equator that passes over Thumba near Thiruvananthapuram using small sounding rockets Realising the immense potential of space technology for national development, Dr. Vikram Sarabhai, the visionary leader envisioned that this powerful technology could play a meaningful role in national development and solving the problems of common man.

Thus, Indian Space programme born in the church beginning, space activities in the country, concentrated on achieving self reliance and developing capability to build and launch communication satellites for television broadcast, telecommunications and meteorological applications; remote sensing satellites for management of natural resources.

The objective of ISRO is to develop space technology and its application to various national tasks. Accordingly, Indian Space Research Organisation (ISRO) has successfully operationalised two major satellite systems namely Indian National Satellites (INSAT) for communication services and Indian Remote Sensing (IRS) satellites for management of natural resources; also, Polar Satellite Launch Vehicle (PSLV) for launching IRS type of satellites and Geostationary Satellite Launch Vehicle (GSLV) for launching INSAT type of satellites.

CURRENT PROGRAMMES:

From the beginning, space activities in the country, concentrated on achieving self reliance and developing capability to build and launch communication satellites for television broadcast, telecommunications and meteorological applications; remote sensing satellites for management of natural resources.
Accordingly, Indian Space Research Organisation (ISRO) has successfully operationalised two major satellite systems namely Indian National Satellites (INSAT) for communication services and Indian Remote Sensing (IRS) satellites for management of natural resources; also, Polar Satellite Launch Vehicle (PSLV) for launching IRS type of satellites and Geostationary Satellite Launch Vehicle (GSLV) for launching INSAT type of satellites.

Indian National Satellite (INSAT) System

The INSAT series, commissioned in 1983, has today become one of the largest domestic satellites systems in the Asia-Pacific region comprising ten satellites in service.

 

                                        Indian Remote Sensing (IRS) Satellite System

The Indian Remote Sensing (IRS) satellite system is one of the largest constellations of remote sensing satellites in operation in the world today. The IRS programme commissioned with the launch of IRS-1A in 1988 presently includes twelve satellites that continue to provide imageries in a variety of spatial resolutions from better than one metre ranging upto 500 metres.

 

                                                                  Launch Vehicles

Today, Indian space programme has become self-reliant with the operationalisation of two satellite launch vehicles, Polar Satellite Launch Vehicle (PSLV), mainly for launching IRS class of satellites in polar orbits and Geosynchronous Satellite Launch Vehicle (GSLV) for launching communication satellites into geo-synchronous transfer orbit. GSLV can carry 2- 2.5 tonne satellite in to 36,000 Kilometer range for geo stationery transfer orbit and India was the sixth country in the world to have this capability.
So far ;

• PSLV has twenty one consecutively successful flights out of twenty two launches
• GSLV has four successful flights of seven launches
