India to launch fifth navigational satellite Wednesday

India will launch its fifth navigation satellite from the southern spaceport of Sriharikota Wednesday, sources said Tuesday.

"The Indian Regional Navigation Satellite System (IRNSS-1E) will be launched at 9.31 a.m. local time on board the country's indigenous Polar Satellite Launch Vehicle (PSLV-31)," the sources said.

The satellite is part of a constellation of satellites, which together will form what's claimed to be India's equivalent of U.S.' global positioning system.

Four satellites have already been launched by the state-owned Indian Space Research Agency and at least three are pending.

Once put into orbit, all the satellites provide accurate position information service encompassing an area of 1,500 km.
