WAAS is to create a signal enhancer, signal correction data - not a GPS signal. There are 38 ground based WAAS stations in the US, Canada, Mexico, HI. They don’t send a GPS signal out, just instructions to correct the existing GPS signal. That signal goes up to the geo sync satellite, which is what our GPS units talk to to get the correction signal.Isn't WAAS stand alone? Then no "approved backup" is required, and anything is better than nothing.
So if GPS is jammed, the WAAS isn’t able to help.
