Indian X-ray Astronomy Experiment (IXAE)
Wide-Field Sensor (WiFS)
IRS-P3 was the sixth satellite in Indian Remote Sensing satellite series, an Earth observation mission launched under the National Natural Resources Management System programme (NNRMS) undertaken by Indian Space Research Organisation (ISRO). The objectives of the mission were processing and interpretation of data generated by its two instruments, the Wide-Field Sensor (WiFS) and Modular Opto-electric Sensor (MOS), developed by the German Aerospace Center (DLR).
IRS-P3 was a remote sensing satellite launched by ISRO on board of Polar Satellite Launch Vehicle (PSLV) launch vehicle for remote sensing of Earth's natural resources. It also hosted a scientific instrument, the Indian X-ray Astronomy Experiment (IXAE), for the study of X-ray astronomy. The IRS-P3 satellite contained an X-ray astronomy instrument, a C-band transponder and two remote sensing instruments. IRS-P3 was one of the satellite in the Indian Remote Sensing Programme of Earth Observation satellites, assembled, launched and maintained by Indian Space Research Organisation. There was no data recording device on board of the IRS-P3 and data was transmitted in real-time to the ground stations in Hyderabad, India and Neustrelitz, Germany.
IRS-P3 carried two remote sensing instruments and one X-ray astronomy experiment:
IRS-P3 was launched by the PSLV-D3 launch vehicle on 21 March 1996, at 04:53 UTC, from Satish Dhawan Space Centre, Sriharikota, India. Periodic calibration of Polar Satellite Launch Vehicle tracking radar was located at tracking stations.
The mission was completed on 15 October 2004 after serving for 8.5 years. With the consecutive successful launches of the PSLV, it was decided not to plan any more Augmented Satellite Launch Vehicle (ASLV) missions.
