A satellite system completed this month will be able to track all planes in the future, its makers have said.
The newly deployed network would allow all planes to be tracked in real time and give air traffic controllers visualisations of where they are at all times.
The system, once live, could put an end to tragic aviation mysteries like the missing flight MH370, which vanished in March 2014 with 239 people on board.
The latest project, known as Iridium NEXT, launched the last 10 of its satellites into space last Friday using a Space X Falcon 9 rocket.
A web of 75 satellites are now orbiting around the Earth and could be tracking all planes in real time by 2020.
The system will a give air traffic controllers and airlines real-time visibility of aircraft around the entire planet for the first time ever.
The US company Iridium has called the network ‘the only communications network with pole-to-pole coverage of the entire planet’.
The official statement from Iridium described it as ‘six polar orbiting planes, each containing 11 crosslinked satellites totaling 66 in the operational constellation, creating a web of coverage around the Earth’.
