IRS-1B was successor to the remote sensing mission called IRS-1A both undertaken by the Indian Space Research Organisation. It was an operational and experimental mission to develop indigenous expertise in satellite imagery.
IRS-1B was the first remote sensing mission undertaken by ISRO using imagery generated by remote sensing technology for land-based applications. The long term objective of the mission was to develop the indigenous capability in the field of remote sensing.
IRS-1B carried 3 solid state Linear Imaging Self-Scanning System cameras:
- LISS-1 (72.5 meter each band ground resolution)
- LlSS-2A & 2B (36.25 meter each band ground resolution)
IRS-1B successfully completed its mission after operating for 12 years and 4 months in December 2003.
