IRS-1C

Launch Date:28.12.1995

irs1c

IRS-1C was the second generation remote sensing satellite developed by ISRO. The satellite carried three distinct and mutually complementing payloads. The payloads enhanced capabilities of IRC-1C as compared to IRS-1A/1B in terms of spatial resolution, provision of additional spectral band, improved repetitivity, ability to acquire stereoscopic image and inclusion of Wide Field Sensor (WiFS) for improved temporal resolution. The Mission was completed on September 21, 2007 after serving for 11 years and 8 months.  
The major objectives of IRS-1C:

1.Design, develop, launch and operate a 3-axis stablised satellite for providing continued space based remote sensing services to the user community with enhance features  

2.Develop new areas of applications to take full advantages of increase spatial, spectral, radiometric and temporal resolution.
