The Indian Remote Sensing Satellite-1A (IRS-1A) was launched on March 17, 1988. IRS-1A is the first of a series of semi-operational/ operational remote sensing satellites developed by Indian Space ... Research Organisation (ISRO) for land-based applications such as agriculture,forestry, geology, and hydrology. The three-axis-stabilized sun-synchronous satellite carries two linear imaging self-scanned sensors (LISS). LISS-1 and LISS-II perform "pushbroom" scanning in visible and near IR bands to acquire images of the earth. Both push-broom scanning sensors operate in the four spectral bands: 0.45-0.52, 0.52-0.59, 0.62-0.68, and 0.77-0.86 micrometer. Local equatorial crossing time is fixed at around 10 a.m. The spacecraft platform, measuring 1.56 m x 1.66 m x 1.10 m, has the payload module attached on the top and a deployable solar array stowed on either side. Attitude control is provided by four momentum wheels, two magnetic torques, and a thruster system. Together these mechanisms provide an estimated accuracy of plus or minus 0.10 deg in all three axes.
