You really do have a short attention span. Australia has been using ADS-B for more than a decade, only possible with ground stations. same with Europe and SE Asia. Nav Canada has been doing the same. Several states either side of the North Atlantic saw the benefit of ADS-B surveillance across the ocean and established the consortium to develop space based surveillance. The report you posted identifies the need for extensive testing before being used operationally. Eventually, if the satellites provide coverage over this end of the world we might benefit - if operators are prepared to pay. There are no free lunches.
