, RESOURCESAT-1 is intended to not only continue the remote sensing data services provided by IRS-1C and IRS-1D, both of which have far outlived their designed mission lives, but also vastly enhance the data quality. The 1360 kg RESOURCESAT-1 was launched into an 817 km high polar sun synchronous orbit by the eighth flight of India's Polar Satellite Launch Vehicle

Polar Satellite Launch Vehicle

The Polar Satellite Launch Vehicle , commonly known by its abbreviation PSLV, is an expendable launch system developed and operated by the Indian Space Research Organisation . It was developed to allow India to launch its Indian Remote Sensing satellites into sun synchronous orbits, a service that...

RESOURCESAT-1 carries three cameras similar to those of IRS-1C and IRS-1D but with vastly improved spatial resolutions - a high resolution Linear Imaging Self Scanner (LISS-4) operating in three spectral bands in the visible

Visible spectrum

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 750 nm. In terms of...
