I assume by "commercial" airspace they mean areas like Class A-B or A-C.

And by "GPS" they appear to mean not just GPS but ADS-B.

The article doesn't say which private aircraft will be expected to install
this equipment, but the deadline is 2020.

I hope the government will not use this as an excuse to decommission VORs..
VORs are the only back-up for a satellite system that is easily jammed or
spoofed (unless you have an INS, but there aren't too many small single-engine
aircraft so equipped).

I carry my waterproof, handheld Lowrance as a
backup. Good for the boat or plane and works
perfectly with independent battery. However, I
haven't taken it underwater and hope not to.

Decommissioning a redundancy system has to
be weighed against the benefit/loss of doing so.
