IRS-1B is the second satellite in the Indian remote sensing series. It was launched from Baikanur cosmodrome, Kazakhstan. IRS-1B is identical to IRS-1A in all respects. The payload and orbital parameters of IRS-1B are the same as that of IRS-1A.
The satellite provided excellent data during the period 1991-2001, outliving its designed life. Many nation level mapping projects were carried out using the data.
