Have you considered using the UBX-TIM-TP qErr correction (the receivers own estimate of the quantisation error for the TIMEPULSE output) instead of sawtooth filtering? I have played with it a little on a u-blox M8, and it sure seemed to smooth things out, but I haven’t made any real measurements on the result. Anders, Thanks for sharing your results! I am a but surprised that you have so large variations, I wonder how much the antenna placement affects the results. Just for fun - can you tell us more about how your antenna is place now?
