Drift of /what/? I've wasted many hours explaining why NTSC is, overall,
better than PAL.

The US video distribution system never had much trouble with phase errors.
European systems did.

Note quite. The GPS system did have the higher resolution data encrypted.
There were several systems to improve accuracy without the keys, such as
broadcasting it on FM radio subcarriers, differential units (multiple
antennas) and so on.

During operation Desert Storm (aka the First Gulf War), there were not enough
millitary GPS units to go around so President Clinton ordered the encryption
turned off.

It has stayed off except in a few limited areas, such as a small portion of
the area between Cuba and the US.

That's why there have been proposed replacement systems by Russia and the EU,
there is always the real possibility that the US will turn on encryption
again and everyone's "SatNav" will be useless. As in "about 100 meters,
maybe two hundred, maybe 100 meters ago, turn in some direction and go for
a while".

Sigh. The NTSC was created for B&W television.

You can't fix stupid. You can't even put a Band-Aid� on it, because it's

Acronyms are always changing, for example:

GSM (French for mobile system group) -> Global System for Mobiles.
DVD (Digital Video Disk) -> Digital Versatile Disk

But they traded color drift for high-brightness ficker; not necessarily
a good choice, since the early color drift of NTSC, being due to
equipment instabilities, was soon fixed by better gear, while PAL's
flicker problem, having been designed in, persisted.

I have a PAL TV set that displays very bright white as black. Someday I'll
replace it. :-)
