India s polar satellite launch vehicle pslv stacking assembly successful launch pslv c6

PSLV-C6 was the sixth operational launch and overall ninth mission of the PSLV program. This launch was also the fifty-fourth launch by Indian Space Research Organisation since its first mission on 1 January 1962. The vehicle carried and injected India's two satellites; Cartosat-1 (a.k.a. IRS-P5) and HAMSAT into the Sun-synchronous orbit. PSLV-C6 was launched at 04:44 hours Coordinated Universal Time (10:14 hours Indian Standard Time) on 5 May 2005 from the second launch pad of the Satish Dhawan Space Centre.

Payload

PSLV-C6 carried and deployed two Indian satellites, Cartosat-1 (a.k.a. IRS-P5) and HAMSAT into the Sun-synchronous orbit. Built by ISRO, Cartosat-1 was a stereoscopic remote sensing satellite and first of the Cartosat series of satellites. HAMSAT was a microsatellite, built for providing satellite based amateur radio satellite to the national as well as the international community of amateur radio operators (HAM).

Launch & planned flight profile

PSLV-C6 was launched at 04:44 hours Coordinated Universal Time (10:14 hours Indian Standard Time) on 5 May 2005 from the second launch pad of the Satish Dhawan Space Centre. The mission was planned with pre-flight prediction of covering overall distance of 622 kilometres (386 mi). Following was the flight profile.
