Data processing system of IRS-1C and data quality evaluation

The Department of Space, Government of India, recognized the need for harnessing space technology for various applications and acquired state-of-art capabilities in the development and establishment of operational remote sensing satellites, Considering the success of IRS series so far, the Department of Space took up the development of IRS-1C satellite. The IRS-1C satellite is an improved version of the earlier IRS missions, both in terms of sensor and re-visit capabilities. The National Remote Sensing Agency at Hyderabad, India, receives and processes data from remote sensing satellites, including IRS-1C, In this article we give details on the entire gamut of data processing facilities including filming, photo processing and quality control facilities, and also give detailed account of the various systems-both hardware and software, As great emphasis is placed by DOS on ensuring quality of the sensors as well as data acquisition and processing systems, therefore, data quality evaluation is also dealt with separately in this article.
