ISRO satellites

Kalpana-1 was the first dedicated meteorological satellite launched by the Indian Space Research Organisation using Polar Satellite Launch Vehicle on 12 September 2002. The satellite is three-axis stabilized and is powered by solar panels, getting up to of power. The METSAT bus was used as the basis for the Chandrayaan lunar orbiter mission of 2008.

The GSAT (Geosynchronous Satellite) series is a family of Indian communications satellites, indigenously developed and operated by the ISRO. The prorgamme was initiated in the early 2000s to create indigenous, multi-purpose, geostationary spacecrafts capable of supporting India's growing needs in telecommunications, broadcasting, broadband, emergency management, reconnaissance and navigation. The programme was supported by the development of Geosynchronous Satellite Launch Vehicle.

Oceansat-2 is the second Indian satellite built primarily for ocean applications. It was a part of the Indian Remote Sensing Programme satellite series. Oceansat-2 is an Indian satellite designed to provide service continuity for operational users of the Ocean Colour Monitor (OCM) instrument on Oceansat-1. It will also enhance the potential of applications in other areas. The OceanSat-2 mission was approved by the government of India on 16 July 2005.

Oceansat-1 or IRS-P4 was the first Indian satellite built primarily for ocean applications. It was a part of the Indian Remote Sensing Programme satellite series. The satellite carried an Ocean Colour Monitor (OCM) and a Multi-frequency Scanning Microwave Radiometer (MSMR) for oceanographic studies. Oceansat-1 thus vastly augment the IRS satellite system of Indian Space Research Organisation (ISRO) comprising four satellites, IRS-1B, IRS-1C, IRS-P3 and IRS-1D and extend remote sensing applications to several newer areas.
