If it wasn't free running, it would be a GPSDO. There is an adjustment for antenna cable length. If you tweak the antenna length adjustment, you can make the sawtooth offset be 0 at any particular sample. But then the osc will drift and the sawtooth will tell you how much it has drifted. > Or is an external delay line or TIC plus software the only way? If it was as simple as you would like, the uBlox guys would have done it already. -- These are my opinions.
