My first inclination, if I were building a timing receiver, would be to make
the PPS output a nice, symmetrical square wave. But pretty much all GPS
timing receivers output an anorexic, dinky little heroin addicted supermodel
sized pulse (from 1 to 150uS wide is typical).

NAVMAN Jupitr-T 26 ms
ONCORE VP ~200ms
UT+ 200ms
M12T 1PPS 200ms 100Hz 2-3ms
these are all timing receivers and the signals will trip serial
receivers without pulse stretching..
So the picture is not that gloomy.
