Much closer than 10 years. The idea is to use existing or soon to be deployed infrastructure from the US ADS-B installation to also perform multilateration. > Yes, yes...

Multilateration can be performed with existing radios being deployed, deriving time synchronization from GPS. Future revision of radio specifications are possible, but are more likely to be incremental changes of existing design rather than more significant architectural changes.
