No, but you need GPS to use WAAS, which enhances GPS accuracy in most,

part, albeit a newer part, of the GPS system.

WAAS is not part of the GPS.

It is all in how you view it, and define it.

Saying it is not part of GPS, is like saying a catalytic converter is not part
of a car. It enhances the car. It is used with the car. Not all cars have
them, especially old ones.

I would say it is part of the car. It certainly can not be put on a sewing
machine.
