The vehicle carried IRS-1D satellite which was deployed in the Sun-synchronous Low Earth orbit.[1][2][3][4] This was India's first launch vehicle built without Russian assistance and PSLV's first operational flight placed IRS-1D into a polar orbit. However, it could not place the satellite in the desired circular orbit but in an elliptical orbit due to a leak of helium gas from one of the components. The mission was termed partial failure since the satellite could not be placed at the desired altitude.[5][6] Mission parameters
LaunchPSLV-C1 was launched at 10:20 a.m. IST on 29 September 1997 from Satish Dhawan Space Centre (then called "Sriharikota Launching Range"). The vehicle placed the IRS-1D satellite in the sun-synchronous orbit.[1][2][3][5] See also
