PSLV-C3 was the third operational launch and overall sixth mission of the PSLV program. This launch was also the forty-sixth launch by Indian Space Research Organisation since its first mission on 1 January 1962. The vehicle carried three satellites which were deployed in the Sun-synchronous Low Earth orbit. The vehicle carried Technology Experiment Satellite (Indian experimental earth observation satellite), BIRD (German earth observation satellite) and PROBA (experimental satellite from Belgium). This was India's and ISRO's second commercial spaceflight. PSLV-C3 was launched at 10:23 a.m. IST on 22 October 2001 from Satish Dhawan Space Centre (then called "Sriharikota Launching Range").
