Success brings India closer to select group of nations with their own satellite navigation system

Sriharikota: India successfully put its fourth navigation satellite into orbit in copy book style on Saturday, bringing the country a step closer to having its own satellite navigation system. The rocket — the Polar Satellite Launch Vehicle (PSLV-C27) — tore into the clear blue evening sky with fierce orange flames at its tail. The expendable rocket had a single but important luggage, the 1,425 kg IRNSS-1D.
