Or use the sawtooth compensation value to control an external variable delay
line circuit to move around the PPS signal from the receiver. This can get
interesting to implement if the receiver can output negative values for the
sawtooth compensation (hint: add a bias to the sawtooth value to make the
compensation values always positive and adjust the antenna cable delay command
to remove the bias value that you add. Oh, and for some receivers you have to
reverse the meaning of positive and negative sawtooth corrections and/or cable
delay values). It is even more interesting if the receiver outputs the
sawtooth correction after the pulse it just generated... hint: get a different
GPS receiver).
