RISAT-2, or Radar Imaging Satellite-2 was an Indian radar imaging reconnaissance satellite that was part of India's RISAT programme. It was procured from Israel Aerospace Industries (IAI) [5] [6] and successfully launched aboard a PSLV-CA launch vehicle at 01:15:00 UTC on 20 April 2009 from the Second Launch Pad at the Satish Dhawan Space Centre. [7]
It is designed to monitor India's borders and as part of anti-infiltration and anti-terrorist operations. [8] The satellite has a mass of 300 kg (660 lb).
RISAT-2 was procured following the 2008 Mumbai attacks, due to delay with the indigenously developed C-band for RISAT-1. It is India's first dedicated radar reconnaissance satellite. [9] RISAT-2 was procured at the cost of USD 200 million from Israel. In terms of configuration and capability it is identical to TecSAR-1 launched in 2008 by ISRO's PSLV which marked the beginning of India-Israel space cooperation. [5] [6] [10]
RISAT-2 was India's first satellite with a synthetic-aperture radar (SAR). It possess day-night as well as all-weather monitoring capability. Potential applications include tracking hostile ships at sea that are deemed a military threat to India. [11]
Though ISRO sought to underplay the satellite's defence applications in its announcements, a substantial number of articles concerning RISAT-2 in the Indian media continue to refer to it as a "spy satellite". [12] This is also supported by the fact that its Israeli sensor is clearly pronounced a military grade sensor by its manufacturer Israel Aerospace Industries (IAI). [5] [6]
ISRO scientists spent tense hours on 19 April 2009 prior to launch as one of the umbilical cords holding the PSLV-CA launch vehicle to the launch pad fell off, damaging nearly six connectors. [13]
The ANUSAT student microsatellite (40 kg) was launched aboard the same launch vehicle as a secondary payload.
RISAT-2 was used to search for and eventually locate wreckage of the helicopter crash that claimed the life of Y. S. Rajasekhara Reddy, chief minister of the state of Andhra Pradesh, as well as the lives of his fellow passengers, while traveling over dense jungles in southern India on 2 September 2009. [14] The satellite reentered over Sumatra on 30 October 2022 at 00:06 UTC [4] [3] after providing payload data for 13 years. [15] [16]
The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
TecSAR-1, also known as TechSAR, Polaris and Ofeq-8, is an Israeli reconnaissance satellite, equipped with a synthetic-aperture radar (SAR) developed by Elta Systems. It was successfully launched at 03:45 UTC on 21 January 2008, by PSLV C-10 launch vehicle, from the Satish Dhawan Space Centre in India.
The Integrated Space Cell was the nodal agency within the Government of India with oversight of the security of its space based military and civilian hardware systems. It was to be jointly operated by all the three services of the Indian Armed Forces, the civilian Defence Research and Development Organisation and the Indian Space Research Organisation (ISRO). This agency was superseded by Defence Space Agency in 2019.

Resourcesat-2 is a follow on mission to Resourcesat-1 and the eighteenth Indian remote sensing satellite built by Indian Space Research Organisation (ISRO). The new satellite provides the same services as the original Resourcesat-1, but was also designed to "provide data with enhanced multispectral and spatial coverage". Compared to Resourcesat-1, LISS-4 multispectral swath has been enhanced from 23 km to 70 km based on user needs. Suitable changes including miniaturization in payload electronics have been incorporated in Resourcesat-2.
Radar Imaging Satellite 1 or RISAT-1, was an Indian remote sensing satellite built and operated by the Indian Space Research Organisation (ISRO). The second RISAT satellite to be launched, it used a C-band 5.35 GHz synthetic-aperture radar (SAR) for Earth observation.

It is one among the seven of the IRNSS constellation of satellites launched to provide navigational services to the region. The satellite was placed in geosynchronous orbit. IRNSS-1E has been successfully launched into orbit on 20 January 2016
EOS-04 or Earth Observation Satellite - 04 is an Indian Space Research Organisation Radar Imaging Satellite designed to provide high-quality images under all weather conditions for applications such as Agriculture, Forestry & Plantations, Soil Moisture & Hydrology and Flood mapping. It is a follow on to RISAT-1 satellite with similar configuration. The satellite is developed by the ISRO and it is the sixth in a series of RISAT satellites.
PSLV-C37 was the 39th mission of the Indian Polar Satellite Launch Vehicle (PSLV) program and its 16th mission in the XL configuration undertaken by the Indian Space Research Organisation (ISRO). Launched on 15 February 2017 from the Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh, the rocket successfully carried and deployed a record number of 104 satellites in Sun-synchronous orbits in a single mission, breaking the earlier record of launching 37 satellites by a Russian Dnepr rocket on 19 June 2014. This record was held until the launch of the Transporter-1 mission by SpaceX on 24 January 2021 which launched 143 satellites.
The Small Satellite Launch Vehicle (SSLV) is a small-lift launch vehicle developed by ISRO to deliver 500 kg (1,100 lb) payload to low Earth orbit or 300 kg (660 lb) payload to Sun-synchronous orbit. The rocket supports multi-orbital drop-offs capability for small satellites.
EMISAT, launched on 1 April 2019, is an Indian reconnaissance satellite under Defence Research and Development Organisation (DRDO) project Kautilya which is a package that provides space-based electronic signal intelligence or ELINT.
