It will fill in the spots radar can't reach

After a recent missing Malaysian Airlines flight, the Federal Aviation Administration (FAA) has decided to mandate GPS-based aircraft tracking on planes. 

According to 9 News, the FAA will require that all planes have a GPS tracking system called Automatic Dependent Surveillance Broadcast (ADS-B) radio network by 2020. 

ADS-B allows controllers to monitor an aircraft using GPS satellite tracking instead of current ground-based radar. The problem with radar is that it doesn't cover some spots around the world, and ADS-B will make sure those particular spots are accounted for (as well as everywhere else around the globe). 

 
Currently, only 100 of the 230 air traffic facilities across the country use ADS-B. But by 2020, all will be onboard. The U.S. already has the ground stations in place for their use, so now it's just a matter of equipping planes with the system. 

In addition to tracking planes, the new system will also provide pilots with more accurate, real time information, like weather, when in flight.

Would this have actually worked for flight 370 though? I guess there would have been more data on where their heading was, but in the middle of the ocean there would have been no transponders.

It says it will broadcast to other aircraft to retransmit the signal like an ad-hoc network/mesh topology. As long as another plane is within few dozen or hundred miles it probably is able to to receive it and retransmit it regardless.

Flight MH370 was already equipped with ADS-B. However, it relied on grounds stations to relay data. Once beyond line of sight, no data (or transmitter is off).
