Poul, i appreciate your comments always a lot! But dynamical methods are especially usefull when the input parameters are subject of change, aren't they? I have seen algorithms that use a a-priori knowledge of the LO's ADEV properties to estimate the GPS's jitter and to adjust the loop time constant according to that. Ok, if you are referring to something like that. But how would you solve the system of equations with TWO unknowns (LO and GPS jitter) if you have only ONE information?
