Attention, there are a lot of "will" in the article regarding the online tracking, with a resolution of 1 minute, of Malaysian planes. The text just says the country will be the first to implement such a revolutionary system, not that it has already tested it. The Aireon group of satellites it not yet operational. It will be in 2018.
KUALA LUMPUR and LONDON, April 18 2017 – SITAONAIR, Aireon and FlightAware today announced that Malaysia Airlines will be the first SITAONAIR airline customer to benefit from a revolutionary flight-tracking partnership. Under the agreement, all Malaysia Airlines aircraft will have access to minute-by-minute, 100% global, flight-tracking data, delivered by SITAONAIR’s AIRCOM® FlightTracker. ...
The Aireon service will be operational in 2018, shortly after the completion of the Iridium NEXT satellite constellation.

We have to wait and see.
We still do not know if such a tracking facility really works.
Even if Malaysia, which has a maximum of a few dozens planes in the air at a given time, will get the online position on the map for all their aircrafts, question still remain if the Aireon can be scaled up and became of real use for all the few thousands planes flying in the world at each moment.
