The supersonic cruise missile BrahMos missed the target at the Army’s range at Pokhran in Rajasthan because its global positioning system (GPS) blanked out, said DRDO officials. The American satellites that run the GPS had been switched off on the day Barack Obama was sworn in the United States President, they said. The missile, therefore, travelled for 112 seconds instead of the slated 84 seconds and fell 7 km away from the target.
The officials could not say whether the Americans had deliberately switched off the GPS satellites to test whether India’s missile mission would be a success without them. They conceded that it was possible to switch off GPS-linked satellites selectively. The failure of the mission, therefore, has underlined the need for India to have its own GPS-linked satellites instead of depending on American or Russian constellations, said an official.
There something fishy about the reasoning here..Wouldn't the scientists know the GPS has been switched off before they launched the missile? or did the switching off happened after the missile was launched? Somehow I don't buy this reasoning.
edit: sorry didn't see this : "he GPS data did not come in time, so the INS data with its uncorrected error was taken as the reference and we missed the target.”
