BERLIN: Two US companies have developed an airline tracking system that they say would prevent planes disappearing in the manner of the Malaysia Airlines MH370. 

Instead of sending tracking signals to ground stations – which means planes' locations can be lost over oceans or remote areas – the new system would beam them to satellites.
