* Two LISS II cameras combined swath
IRS-1B
- Launched in: August 29, 1991
- Out of service since: 1996
- Repeat Cycle: 22 Days
- Orbit Height: 904 Km
- Orbit Type: Sun Synchronous
(For technical specification see Table 1 and 2)
IRS-1C and IRS-1D
IRS-1C and IRS-1D are identical and were launched in December 1995 and September 1997, respectively, the latter by India's Polar Satellite Launch Vehicle (PSLV). They carry three cameras, Panchromatic Camera (PAN), Linear Imaging Self Scanner (LISS-III) and Wide Field Sensor (WiFS).
