The Indian Space Research Organisation (ISRO) today launched the IRNSS-1I navigation satellite, the eighth such satellite to be a part of a constellation, from Sriharikota in Andhra Pradesh.

PSLV-C41/IRNSS-1I Mission blasted off at 4.04am from the first launch pad at the Sathish Dhawan Space Centre. It absolutely was an ordinary lift-off, ISRO officials said.

IRNSS-1I is expected to restore IRNSS-1A, the first of the seven navigation satellites, that has been rendered ineffective following its three rubidium atomic clocks failed. The seven satellites are the element of the NavICnavigation satellite constellation.

The launch is ISRO’s second attempt at sending an upgraded satellite.

The last mission of a PSLV carrying IRNSS-1H in August this past year failed after the heat shield covering the satellite failed to separate.

The IRNSS-1I mission occurs a couple of weeks after the space agency launched GSAT-6A on board GSLV Mk-II. Although rocket placed GSAT-6A in orbit, the ISRO lost communication with the satellite within two days.
