 This dual purpose remote-sensing and the weather satellite program is known as the PRS program, and in January 2007, a feasibility and system definition study was concluded by SUPARCO, which recommended the launch of an optical and Synthetic Aperture Radar (SAR) satellite to ensure that the domestic and international user requirements are competitively met.In July 2007, the development of the first prototype optical satellite in this PRS program was launched, the manufacturing of the satellite was planned in the third quarter of year 2008.Initially, SUPARCO plans to launch an optical satellite with payload of 2.5-meter PAN in 700 km sun-synchronous orbit, which will be followed by a series of optical and SAR satellites in the future.
