The 1250 kg IRS-1D is an Indian remote sensing Sun-synchronous orbiter that was launched by the PSLV-C1 (Polar Satellite Launch Vehicle) launch vehicle from Sriharikota (in southeast India) at 04:47 UTC. The 44.4 metres, four-stage, 494-ton PSLV-1C is now an operational vehicle, after earlier test launches, it is the fourth launch vehicle PSLV.

IRS – 1D, a follow on satellite to IRS – 1C belongs to the second generation of IRS series of Satellites. It has 3 payloads viz., PAN, LISS 3 & WiFS.

IRS 1D Sensors Linear Imaging Self Scanning Sensor - 3 (LISS-3) This sensor is configured to provide imageries in three visible bands as well as in short-wave infrared band. The resolution and swath for visible bands are 23.5 m and 142 km, respectively. The detector is a 6000 element CCD based linear array with a pixel

India's remote sensing programme under the Indian Space Research Organization (ISRO) started off in 1988 with the IRS-1A, the first of the series of indigenous state-of-art operating remote sensing satellites, which was successfully launched into a polar Sun-synchronous orbit on March 17, 1988, from the Soviet Cosmodrome at Baikonur.

IRS-1C and IRS-1D were identical Earth-imaging satellites launched two years apart: IRS-1C was launched in 1995 and ceased operations in 2007; IRS-1D was launched in 1997 and ceased operations in 2010

Jun 1, 2012 · IRS-1C and IRS-1D are three-axis body-stabilized spacecraft (identical twins). The attitude is sensed by star sensors, Earth sensors and gyros. Actuators: four reaction wheels, two magnetic torquers, 16 one Newton hydrazine trusters; one 11 Newton thruster.

IRS-1C/ID, the identical twin satellites, used LISS-III, PAN (Panchromatic camera) and WiFS (Wide Field Sensor) camera sensors operating in pushbroom scanning mode using solid state charge-coupled-device detectors.

India has joined an elite space club with the successful launch of IRS-1D, a 1,200 kg. remote sensing satellite from the Indian soil on September 29, 1997. Only a handful of countries the US, Russia, Japan, China and France can boast of both satellite-building and …

May 1, 2015 · IRS-1D is an Indian remote sensing Sun-synchronous orbiter that was launched by a PSLV-1C (Polar Satellite Launch Vehicle) rocket from Shriharikota (in southeast India) at 04:47 UT. (The 44.4 meter, four-stage, 468 ton PSLV-1C complex is now an operational vehicle, after earlier test launches.)

IRS-1D was an Earth-imaging satellite from the Indian Space Research Organisation (ISRO) which launched on 29 September 1997 and ceased operations in 2010. The IRS (Indian Remote Sensing) satellites form a large family of Earth observation satellites operated by ISRO.
